## VTC Apps Catalog (484 Public Apps)
- [2D Fluid Flow Simulator](https://vtc.com/apps/fluidflow) ([Launch](https://fluidflow.apps.vtc.com)) [Education]: Place obstacles in a flow and watch a real incompressible-fluid solver produce genuine vortex shedding downstream — a real, live von-Kármán-style wake pattern, not a canned animation. Turn up the flow speed or turn down the viscosity and watch the wake transition from smooth and steady to periodically shedding vortices. This app's solver becomes the shared engine for two other fluid apps later in the collection, so what you see here is the real computational core, not a simplified preview.
- [3D Airfoil Flow Visualizer](https://vtc.com/apps/airfoilflow) ([Launch](https://airfoilflow.apps.vtc.com)) [Education]: Adjust angle of attack on a 3D wing cross-section and watch streamlines speed up over the top surface and slow down underneath, generating real lift computed from the Kutta-Joukowski relationship. The drag reading stays at exactly zero the whole time — not a bug, but d'Alembert's paradox, a genuine and famous result of this idealized, frictionless flow model, explained right alongside the number. A clear, honest way to see how lift emerges from pure potential-flow theory, and exactly where that theory's assumptions leave real-world drag out of the picture.
- [3D Gravitational Lensing Visualizer](https://vtc.com/apps/gravitational) ([Launch](https://gravitational.apps.vtc.com)) [Education]: Fire parallel light rays past a massive object and watch them bend — gently for rays passing far away, matching the standard weak-field formula almost exactly, and dramatically for rays passing close to a black-hole preset, where that same simple formula breaks down completely. Both regimes are computed from real geodesic integration, not a single formula stretched past where it's valid. A rare chance to see, concretely, exactly where a textbook approximation stops working and why.
- [3D Hydrogen Atom Orbital Viewer](https://vtc.com/apps/hydrogenatom) ([Launch](https://hydrogenatom.apps.vtc.com)) [Education]: Select quantum numbers and watch the real hydrogen wavefunction render as a 3D probability cloud — the familiar spherical 1s ground state, the dumbbell-shaped 2p orbitals, and beyond. A radial probability plot alongside the 3D view peaks right around the distance the simple Bohr model predicts, and the node count in every orbital matches the exact quantum-mechanical formula. The closest thing to actually seeing an electron's probability cloud rather than just being told it exists.
- [3D Ripple Tank](https://vtc.com/apps/rippletank) ([Launch](https://rippletank.apps.vtc.com)) [Education]: A classic ripple tank, but rendered as a real deforming 3D water surface instead of a flat top-down heatmap. Place obstacles for reflection, slits for diffraction, and depth zones for refraction — the wave visibly bends when crossing from a deep zone into a shallow one, just like light bending through a different medium. Built on a genuine wave-equation solver, so unusual setups produce real, correct wave behavior rather than a canned animation.
- [3D Spacetime Curvature Visualizer](https://vtc.com/apps/spacetime) ([Launch](https://spacetime.apps.vtc.com)) [Education]: The classic "rubber sheet" analogy, done properly: the depression's shape comes from the real Flamm's paraboloid formula, not an arbitrary bowl. A test particle orbits on top of it — but its path comes from genuine orbital mechanics, not from rolling down the sheet's slope, since that popular shortcut is famously inexact and this app deliberately avoids it. A second mass can be added to see an (honestly labeled) approximate superposition of two curved regions.
- [Accounting Practice](https://vtc.com/apps/practice) ([Launch](https://practice.apps.vtc.com)) [Finance]: Run your accounting firm in your Space: client companies, recurring compliance tasks with deadlines and a calendar, staff assignments and workload, time logs, and fee notes built from logged time, with read-only links to your VTC Invoicing invoices.
- [Ad Maker](https://vtc.com/apps/screenmo) ([Launch](https://screenmo.apps.vtc.com)) [Business]: Make video ads for your Space in minutes — brand kit, AI script and voiceover, 16:9, 1:1 or 9:16, then send straight to your Space Ads.
- [Admissions](https://vtc.com/apps/eduadmit) ([Launch](https://eduadmit.apps.vtc.com)) [Education]: Simplifies the complete student admission process from application to acceptance. Applicants can submit forms and required documents online. Admission teams can review applications, communicate with families, and manage selection workflows. Status updates keep applicants informed throughout the process. The app creates a faster and more transparent admission experience.

- [AutoHub](https://vtc.com/apps/autohub) ([Launch](https://autohub.apps.vtc.com)) [Productivity]: AutoHub is a comprehensive vehicle management application that allows users to: Search for vehicles from a worldwide vehicle catalogue. View detailed specifications for cars, motorcycles, trucks, and other supported vehicle types. Add vehicles to their personal garage. Maintain service history. Track fuel usage. Store RC, insurance, PUC and other documents. Track vehicle expenses. Manage maintenance schedules. Receive reminders for insurance, PUC, service, tyres and other vehicle-related events.
- [Autotrader](https://vtc.com/apps/autotrader) ([Launch](https://autotrader.apps.vtc.com)) [Lifestyle]: Buy and sell new and used vehicles, cars, motorcycles and trucks
- [Band Structure Explorer](https://vtc.com/apps/bandstructure) ([Launch](https://bandstructure.apps.vtc.com)) [Education]: A real Kronig-Penney model calculation shows exactly how a periodic potential splits a continuous energy spectrum into allowed bands separated by forbidden gaps. Preset conductor, semiconductor, and insulator configurations sit side by side, distinguished purely by gap size and where the Fermi level lands — with silicon's real, cited band gap used as the semiconductor reference point. A genuine, if simplified, look at the actual physics behind why some materials conduct electricity and others don't.
- [Barter](https://vtc.com/apps/barter) ([Launch](https://barter.apps.vtc.com)) [Shopping]: Trade goods and services directly with other members. List what you have, say what you need, and make swaps without using cash.

- [Beat Frequency](https://vtc.com/apps/beatfrequency) ([Launch](https://beatfrequency.apps.vtc.com)) [Education]: Combine two close-frequency tones and watch — and hear — the classic "wah-wah-wah" beat pattern emerge. The beat frequency is measured two independent ways: from the simple formula and from actually timing the envelope's peaks in the simulated waveform, and they always agree. Play with amplitude and frequency sliders while listening to the real synthesized audio, so the abstract idea of "interference in time" becomes something you can literally hear.
- [Behavior](https://vtc.com/apps/edubehavior) ([Launch](https://edubehavior.apps.vtc.com)) [Education]: Tracks student behavior, achievements, and classroom conduct in one place. Teachers can record positive actions, incidents, and observations quickly. Students and parents receive clear insights into behavior patterns. Reports help identify areas for improvement and celebrate progress. It encourages accountability and positive classroom culture.
- [Bernoulli's Principle Pipe Flow Lab](https://vtc.com/apps/bernoullis) ([Launch](https://bernoullis.apps.vtc.com)) [Education]: Build a pipe with a Venturi-style constriction and watch flow speed up through the narrow section while pressure visibly drops, exactly as Bernoulli's equation predicts — with particles animated at the correct local speed throughout. Add an elevation change and watch the pressure respond to that separately from the velocity effect, isolating each contribution. A fast, lightweight, purely analytic companion to the heavier full fluid-simulator app elsewhere in the collection.
- [Bifurcation Diagram Lab](https://vtc.com/apps/bifurcationdiagram) ([Launch](https://bifurcationdiagram.apps.vtc.com)) [Education]: The logistic map's full period-doubling road to chaos, rendered as a real bifurcation diagram: one stable value splits into two, then four, then eight, the splits crowding closer together until the system tips into chaos — with a genuine periodic window still visible inside the chaotic region. A live Feigenbaum-constant estimate converges toward its famous universal value as more period-doublings are included, a real and rather beautiful result that shows up across many unrelated chaotic systems. Pick any parameter value and watch its actual iteration sequence alongside the diagram to see exactly what "chaotic" looks like as a plain list of numbers.
- [Binary Star System Simulator](https://vtc.com/apps/binarystar) ([Launch](https://binarystar.apps.vtc.com)) [Education]: Two stars orbiting their shared center of mass — correctly scaled inverse to their masses, so a heavy star traces a tight little loop while its lighter partner swings wide. A radial-velocity curve tracks the wobble a distant observer would actually measure via Doppler spectroscopy, flattening to zero at face-on inclination and peaking at edge-on, exactly as real observational astronomy would find it. The same detection technique used to find real exoplanets and binary stars, laid out step by step.
- [Bitcoin Price](https://vtc.com/apps/bitcoinprice) ([Launch](https://preev.com)) [Finance]: Get latest Bitcoin price from Preev
- [Bite Log](https://vtc.com/apps/bitelog) ([Launch](https://bitelog.apps.vtc.com)) [Food]: Bitelog helps you remember every place you visit by saving what you ate, what you liked, and your personal notes.

- [Black Hole Accretion Disk Visualizer](https://vtc.com/apps/blackhole) ([Launch](https://blackhole.apps.vtc.com)) [Education]: An accretion disk rendered with a real inner-to-outer brightness gradient, viewable from any angle around a black hole whose size scales correctly with mass. Flip on relativistic beaming and watch the side of the disk spinning toward you light up noticeably brighter than the side spinning away — a real, documented effect seen in actual astrophysical images, not an artistic flourish. Toggle beaming off and back on for a direct, satisfying before-and-after comparison.
- [Blackbody Radiation Explorer (3D)](https://vtc.com/apps/blackbody) ([Launch](https://blackbody.apps.vtc.com)) [Education]: Sweep temperature and watch a full Planck spectral-radiance curve reshape live, with the peak wavelength tracking Wien's displacement law exactly. A 3D glowing object updates its color in real time to match the computed blackbody color at that temperature — red-hot, then white-hot, then blue-white as temperature climbs. Preset reference temperatures (an incandescent filament, the Sun's surface) ground the abstract curve in things you actually recognize.
- [Bloch Sphere Qubit Visualizer](https://vtc.com/apps/blochsphere) ([Launch](https://blochsphere.apps.vtc.com)) [Education]: Watch a qubit's state as a literal point on a sphere, and apply real quantum gates — X, Y, Z, Hadamard, phase gates — as geometric rotations you can see happen in 3D. Apply Hadamard twice and watch the state land back exactly where it started, a direct visual proof that H is its own inverse. A gate-sequence log tracks every operation, so you can build up a short quantum circuit and watch its cumulative effect unfold on the sphere step by step.
- [Blogs](https://vtc.com/apps/blog) ([Launch](https://blog.apps.vtc.com)) [Lifestyle]: The Group Blog app lets communities, teams, and organizations publish shared posts, articles, and updates for their members.

- [Buoyancy & Floating Objects Lab](https://vtc.com/apps/buoyancy) ([Launch](https://buoyancy.apps.vtc.com)) [Education]: Push a floating object underwater and let go — watch it bob up and down, the motion damping out over a few oscillations until it settles at exactly the submersion depth Archimedes' principle predicts. Compare a denser object that simply sinks against one that floats, and swap fluids to watch the equilibrium depth shift accordingly. A simplified tipping demo rounds it out with a taste of why a wide, flat block floats more stably than a tall, narrow one.
- [Bursaries](https://vtc.com/apps/edubursary) ([Launch](https://edubursary.apps.vtc.com)) [Education]: Manages bursary applications, eligibility reviews, and financial assistance awards. Students and families can submit supporting documents digitally. Administrators can review applications and track approval status efficiently. Secure records ensure fairness and transparency throughout the process. The app simplifies access to financial support for eligible students.

The app makes school meal management efficient and convenient.
- [Capacitor & Inductor Charge/Discharge Lab](https://vtc.com/apps/capacitor) ([Launch](https://capacitor.apps.vtc.com)) [Education]: A focused explorer for RC, RL, and RLC transient response, built around the idea of a time constant you can actually see on the curve, not just a number in a formula. Watch an RC circuit reach exactly 63% of its final voltage right at t equals RC, marked directly on the plot. Sweep resistance across the critical-damping threshold in RLC mode and watch the response curve visibly shift between oscillatory ringing and smooth, non-oscillatory settling.
- [Care Circle](https://vtc.com/apps/carecircle) ([Launch](https://carecircle.apps.vtc.com)) [Community]: Prayer and care requests for churches and faith-based groups. Any member can send a prayer or care request, kept private or shared on the circle's prayer list (with their name or anonymously), and others can tap I prayed. Pastors and leaders triage requests, set urgency and assign caregivers. Caregivers schedule visits, calls or meals, mark them done and keep private care notes that the requester never sees. Every change is kept in a history, requesters get in-app alerts when a caregiver is assigned or a visit is planned, and leaders see response-time reports with CSV export. Admins choose the leaders and caregivers in Settings.
- [Career planning](https://vtc.com/apps/educareers) ([Launch](https://educareers.apps.vtc.com)) [Education]: Helps students explore career pathways based on their interests and strengths. It provides guidance on courses, skills, certifications, and future opportunities. Students can set goals and track their career development over time. Teachers and counselors can offer personalized advice. The app prepares learners for higher education and professional success.
- [Carnot Cycle Lab](https://vtc.com/apps/thermodynamic) ([Launch](https://thermodynamic.apps.vtc.com)) [Education]: Compare the Carnot, Otto, Diesel, and Brayton thermodynamic cycles side by side on live PV and TS diagrams, each correctly built from its own real sequence of isothermal, adiabatic, isochoric, and isobaric processes. Efficiency is computed directly from the work and heat in each cycle, then cross-checked against the standard closed-form efficiency formulas where they exist — Carnot's famous 1 minus Tcold-over-Thot among them. A great way to see, concretely, why an idealized Otto cycle engine and an idealized Diesel cycle engine at the same compression ratio don't perform the same.
- [Cash Flow Buffer Planner](https://vtc.com/apps/cashflow) ([Launch](https://cashflow.apps.vtc.com)) [Finance]: Plan your money a month ahead and keep a safety-net buffer. Add recurring and one-time bills and income (weekly, every two weeks, monthly, quarterly, yearly), set your current balance and everyday spending, and see a 30, 60 or 90-day day-by-day projected balance with a chart and table. Choose your buffer as a fixed amount or weeks of expenses; the dashboard gauge shows Healthy, Below buffer or Overdraft risk, the next 7 days of bills and income, and totals. When your balance is about to drop below the buffer you get an in-app alert with suggested actions you can apply or dismiss: move money in before the gap, trim everyday spending, or move a non-essential bill after payday. Any currency with local number and date formats, CSV export of items and projection, JSON backup and import, and example data to explore. Everything is private to you and follows you across Spaces and devices. Estimates only, not financial advice.
- [Cell Cycle Simulator](https://vtc.com/apps/cellcycle) ([Launch](https://cellcycle.apps.vtc.com)) [Education]: A cyclin-CDK oscillator drives a cell through G1, S, G2 and M on a live clock, with cyclin building up, triggering mitosis and being destroyed at anaphase to reset the cycle. Switch on DNA damage and a checkpoint holds the cell back; remove it and the cycle resumes. The model is a published, simplified oscillator, labeled as qualitative, and the app compares its proportions with typical human cell timings. Three depth levels take it from a plain-language "molecular timer" view to the full equations and parameter editing.
- [Cellular Respiration & ATP Accounting](https://vtc.com/apps/cellularrespiration) ([Launch](https://cellularrespiration.apps.vtc.com)) [Education]: Trace one glucose molecule through glycolysis, pyruvate oxidation, the Krebs cycle and oxidative phosphorylation, with live counts of NADH, FADH2, CO2 and ATP at every stage. The ATP total comes with its honest range, about 30 to 32 with current P/O ratios, and the shuttle choice and the older 36–38 figure are explained instead of hidden. Cut off the oxygen or block the electron transport chain and the app shows the backup, then switches to fermentation and its yield of just two ATP. A carbon and atom balance keeps every step accountable.
- [Center of Mass & Moment of Inertia Builder](https://vtc.com/apps/centerofmass) ([Launch](https://centerofmass.apps.vtc.com)) [Education]: Drop point masses onto a canvas and watch the center of mass update live as you drag them around. Draw a rotation axis anywhere — not just through the center of mass — and see moment of inertia recalculate instantly, directly demonstrating the parallel axis theorem in action. Built-up shape presets (a rod or ring made of many point masses) let you watch the discrete approximation converge toward the exact textbook formula as you add more points.
- [Central Dogma Simulator](https://vtc.com/apps/centraldogma) ([Launch](https://centraldogma.apps.vtc.com)) [Education]: Follow a gene from DNA to protein: transcribe it into mRNA, process it (cap, tail and splicing in eukaryote mode), and translate it codon by codon with the standard genetic code. The app makes the strand relationships explicit, showing how the mRNA matches the coding strand and complements the template, which is the point people most often mix up. A mutation explorer applies substitutions, insertions and deletions and classifies each as silent, missense, nonsense or frameshift, with the original and mutant proteins side by side. This app handles the sequence logic; the 3D ribosome app handles the machinery.
- [Certificates](https://vtc.com/apps/certificates) ([Launch](https://certificates.apps.vtc.com)) [Community]: Create custom certificate templates, issue PDFs to space members in one flow, and let recipients view, download, and share their credentials. Admins control who can issue, and a searchable directory keeps issued certificates easy to find.
- [Certs](https://vtc.com/apps/certs) ([Launch](https://certs.apps.vtc.com)) [Work]: Track members' training certificates and spot the ones that are expired or expiring in the next 30, 60 or 90 days.
- [Chaperone Shifts](https://vtc.com/apps/chaperone) ([Launch](https://chaperone.apps.vtc.com)) [Education]: Plan chaperones for school events in your Space. Organisers create field trips, dances or sports days with chaperone roles, requirements and a number of slots per role. Parents see open slots, sign up for a role for the whole event or part of it, and give consent with a checkbox and their typed name. Each parent sees and changes only their own sign-ups; other families' names, phone numbers and consent stay private to organisers. Organisers add parents on their behalf, lock the roster when it is final, print it or export it to CSV, and every change is kept in an audit log. English, Spanish and French.
- [Charged Particle Motion Lab](https://vtc.com/apps/chargedparticle) ([Launch](https://chargedparticle.apps.vtc.com)) [Education]: Fire charged particles through electric and magnetic fields and watch three classic experiments play out: cyclotron circular motion, a velocity selector that only lets one exact speed pass through undeflected, and a full mass spectrometer that separates particles by mass-to-charge ratio right in front of you. Every scenario cross-checks its own result — the mass spectrometer literally reads back the mass-to-charge ratio it used to launch each particle. A free-play mode lets you set arbitrary fields and launch a particle to explore effects like E cross B drift on your own.
- [Check In](https://vtc.com/apps/check) ([Launch](https://check.apps.vtc.com)) [Work]: Quick tap to record attendance for meetings, classes, events, or shifts.
- [Chemical Nomenclature Trainer](https://vtc.com/apps/chemicaltrainer) ([Launch](https://chemicaltrainer.apps.vtc.com)) [Education]: A procedurally-generated quiz that drills formula-to-name and name-to-formula translation across simple ionic, variable-charge metal, and polyatomic compounds. Shares its naming engine with the ion builder so the two apps never disagree.
- [Chemistry Calculator](https://vtc.com/apps/chcalculator) ([Launch](https://chcalculator.apps.vtc.com)) [Education]: A single dense page of fast, no-frills versions of the family's most common calculations — molar mass, molarity, dilution, gas law, density, quick pH — for when you just need the number, not the worked steps. Links out to the deeper standalone apps when more detail is needed.
- [Circuit Sandbox](https://vtc.com/apps/circuitsandbox) ([Launch](https://circuitsandbox.apps.vtc.com)) [Education]: A genuine SPICE-lite circuit simulator: drag resistors, capacitors, inductors, and sources onto a grid, wire them together, and watch current flow and voltages update live. Probe any node for a full transient-response plot — an RC circuit charging, an RLC circuit ringing — all solved from a real modified-nodal-analysis engine, not canned formulas. Flip a switch mid-simulation to trigger a transient and watch the circuit actually respond in real time.
- [Classifier Playground](https://vtc.com/apps/classifier) ([Launch](https://classifier.apps.vtc.com)) [Education]: Place your own 2D points and watch a decision boundary form live, including overfitting.
- [Clip Maker](https://vtc.com/apps/clipmaker) ([Launch](https://clipmaker.apps.vtc.com)) [Social]: Clip Maker: make short AI video clips for your Space. Describe a scene or start from a still image, pick a model, aspect ratio (16:9, 9:16 or 1:1), length and resolution, and see the cost in credits before you confirm. Clips are saved to your library with title, tags and a share option, so you can keep them private or share them with your Space. Save presets for looks you use often, start from example presets, download MP4s and export your activity to CSV.
- [Clubs](https://vtc.com/apps/educlubs) ([Launch](https://educlubs.apps.vtc.com)) [Education]: Helps schools manage extracurricular clubs, memberships, and activities efficiently. Students can explore available clubs and register based on their interests. Club leaders can organize meetings, events, and announcements from one place. Participation records help recognize student involvement beyond academics. The app encourages creativity, collaboration, and holistic student development.
- [Code Lab](https://vtc.com/apps/codelab) ([Launch](https://codelab.apps.vtc.com)) [Education]: Learn to build real apps step by step, with interactive coding lessons, explanations, challenges, and AI guidance based on working projects.
- [Coffee Roulette](https://vtc.com/apps/coffeeroulette) ([Launch](https://coffeeroulette.apps.vtc.com)) [Community]: Coffee Roulette: random one-to-one coffee chats for any community Space. Members opt in, add a few interests, their availability and a preferred format (in person, video or either), and get a new match each round with a simple card showing their partner. After meeting they mark We met or Couldn't meet and leave a quick rating. Organisers start rounds with a pairing preview they can shuffle before confirming, avoid repeat pairs, see participants and newcomers, review feedback and met rates, export each round to CSV and check an activity log.
- [Collision Lab](https://vtc.com/apps/collisionlab) ([Launch](https://collisionlab.apps.vtc.com)) [Education]: Two carts on a track, or a full 2D billiard sandbox — either way, an adjustable restitution slider lets you dial collisions anywhere from perfectly elastic to perfectly inelastic. Live bar charts track total momentum and kinetic energy through every collision, so you can watch momentum stay flat while energy visibly drains away as restitution drops. A good hands-on way to see why "conservation of momentum" and "conservation of energy" aren't the same rule.
- [Commission Split](https://vtc.com/apps/commissionsplit) ([Launch](https://commissionsplit.apps.vtc.com)) [Business]: Track real-estate commissions and agent payouts in your Space. Agents log closed deals with sale price, commission rate and referral fee, and see a live split preview; brokers can add a co-agent. Brokers set split rules (percentage, flat fee or tiered), assign them to agents, and approve or return submitted deals. Accountants see approved deals waiting for payout, mark them paid with a reference, and export deals and payouts to CSV for payroll. Every change is kept in a full audit history, and reports show gross commission, agent and brokerage shares per agent and per month.
- [Compliance](https://vtc.com/apps/compliance) ([Launch](https://compliance.apps.vtc.com)) [Work]
- [Concept Maps](https://vtc.com/apps/conceptmap) ([Launch](https://conceptmap.apps.vtc.com)) [Education]: Build concept maps of what you are learning and turn them into flashcards that schedule themselves. Drag nodes on a canvas, link ideas with labelled arrows, add notes, tags, images and formulas, then mark any node as a card. Study due cards with Again, Hard, Good and Easy and the app spaces your reviews (SM-2), or study one branch of a map at a time. Analytics show mastery by branch, review streaks, your weakest cards and a 14-day forecast. Print a map, export cards to CSV and back up maps as JSON. Your maps are private to you.
- [Contact](https://vtc.com/apps/contact) ([Launch](https://contact.apps.vtc.com)) [Business]: Manage all customer communications from one place with AI-powered phone calls, WhatsApp, SMS, voicemail, callbacks, and business messaging
- [Context & Memory](https://vtc.com/apps/contextmemory) ([Launch](https://contextmemory.apps.vtc.com)) [Education]: Visualize the KV cache and why long context windows get expensive fast.
- [Contracts](https://vtc.com/apps/contracts) ([Launch](https://contracts.apps.vtc.com)) [Business]: Manage your Space's contracts from draft to renewal. The team builds a library of reusable clauses and templates, keeps a list of customers and suppliers, drafts contracts with dates and value, sends them for approval, records signatures, and tracks obligations such as payments, milestones and renewals, with a dashboard filtered by expiring soon, pending approval and awaiting signature. Renewal notices, expiry and overdue obligations are set automatically with the Space's scheduled actions, with optional email reminders. Members can submit contract requests, review a shared contract and sign it by typed name, and the team records that signature on the contract. Export to CSV and add example data in one tap. English, Spanish and French.
- [Cosmic Expansion & Redshift Simulator](https://vtc.com/apps/cosmicexpansion) ([Launch](https://cosmicexpansion.apps.vtc.com)) [Education]: An expanding grid of galaxies where every single point recedes from every other point — no special center, a genuinely common misconception this app makes impossible to miss. Hubble's law plays out live as distance and recession speed scale together, and a redshift calculator carefully distinguishes ordinary Doppler-style recession from the more correct "space itself is stretching" cosmological picture. A qualitative expansion-history timeline rounds it out, showing how the universe's growth rate has genuinely changed across different cosmic eras.
- [Coupled Oscillator Normal Modes](https://vtc.com/apps/coupledoscillator) ([Launch](https://coupledoscillator.apps.vtc.com)) [Education]: Build any network of masses and springs — a chain, a ring, a grid, or something entirely custom — and see its true normal modes computed via real eigenvalue decomposition. Click any mode to watch the system oscillate in that pure shape alone, or drag masses into an arbitrary starting position and watch the app decompose it into a mix of modes before it evolves. Unlike a driven, damped oscillator, this app is about the system's own natural vibration patterns, undisturbed by outside forces.
- [Coupled Pendulum Wave Chain](https://vtc.com/apps/coupledpendulum) ([Launch](https://coupledpendulum.apps.vtc.com)) [Education]: A chain of coupled pendulums that behaves like a wave-on-a-string with a twist: because each pendulum has its own gravity-driven restoring force, the chain has a genuine low-frequency cutoff that an ordinary string doesn't. Drive the chain below that cutoff and the disturbance dies out within a few pendulum-lengths instead of traveling; drive it above cutoff and a clean wave propagates down the line. A concrete, hands-on way to see how adding a local restoring force changes wave behavior at a fundamental level.
- [Course catalog](https://vtc.com/apps/educatalog) ([Launch](https://educatalog.apps.vtc.com)) [Education]: Provides a searchable collection of all courses and academic programs offered by the institution. Students can explore course descriptions, prerequisites, credits, schedules, and available options. Filters make it easy to find courses that match academic interests and requirements. Updated information helps students make informed study choices. The catalog serves as a central reference for academic planning.
- [Course registration](https://vtc.com/apps/eduregister) ([Launch](https://eduregister.apps.vtc.com)) [Education]: Allows students to search, select, and register for courses online. Course availability, prerequisites, schedules, and credit information can be displayed before registration. The system can identify conflicts or unmet requirements during enrollment. Students can review and manage their registered courses from one place. The app makes course selection faster, clearer, and more reliable.
- [CoWork](https://vtc.com/apps/cowork) ([Launch](https://cowork.apps.vtc.com)) [Business]: Create and manage your coworking space with ease. Add your location, define pass types, register members, and sell or assign passes directly. Accept free-pass applications, track usage, and publish your space to the global CoPass directory to attract new members and remote teams.
- [CRISPR-Cas9 Guide Design & Editing Simulator](https://vtc.com/apps/crisprcas9) ([Launch](https://crisprcas9.apps.vtc.com)) [Education]: Paste a DNA sequence and the app scans both strands for NGG PAM sites, lists the candidate 20-nucleotide guides and marks where Cas9 would cut. A mismatch table shows why changes near the PAM matter more than distant ones, and a repair simulator compares error-prone insertions and deletions, with in-frame or frameshift outcomes, against precise repair from a donor template. It's an educational tool and says clearly that it is not a real guide-design or off-target predictor.
- [Crystal Lattice](https://vtc.com/apps/crystallattice) ([Launch](https://crystallattice.apps.vtc.com)) [Education]: Renders the classic unit cell types — simple cubic, BCC, FCC, HCP, diamond, rock salt — in interactive 3D with correct atom placement, and computes coordination number, packing efficiency, and theoretical density. Includes a tiled view showing how the cell repeats into a full lattice.
- [Curriculum](https://vtc.com/apps/curriculum) ([Launch](https://curriculum.apps.vtc.com)) [Education]: District curriculum alignment dashboard: standards, courses, assessments and coverage heatmaps.
- [Customers](https://vtc.com/apps/customers) ([Launch](https://customers.apps.vtc.com)) [Business]: The Customers app is the core of your CRM workflow. Create and manage customers and contacts, define custom fields, store notes, attach files, and connect records across your other Posif apps — invoicing, support, projects, sales, and more. It’s a flexible foundation that keeps all customer data organized and available wherever your apps need it.
- [Data Prep](https://vtc.com/apps/dataprep) ([Launch](https://dataprep.apps.vtc.com)) [Work]: Clean, join and validate uploaded or pasted data, schedule refreshes, and turn the results into charts, KPIs and tables you can embed in any VTC app or portal. Step-by-step pipelines with run history, private or shared visibility and editors.
- [Dating](https://vtc.com/apps/dating) ([Launch](https://dating.apps.vtc.com)) [Entertainment]: Datting with swipe and search - identity and messaging are separate to your identity on the network
- [DB Manager](https://vtc.com/apps/dbm) ([Launch](https://dbm.apps.vtc.com)) [Tools]: Manage the data collections in your space
- [Deal Rotation](https://vtc.com/apps/dealrotation) ([Launch](https://dealrotation.apps.vtc.com)) [Work]: Fair, automatic deal rotation for small sales teams in your Space. Managers set rotation policies (round-robin, skill-based or territory-based) with an acceptance window and a follow-up cadence. Each new deal is offered to the next eligible rep, who accepts or rejects it with a reason; rejected or expired offers rotate to the next rep, and deals with no eligible rep are flagged as coverage gaps. Accepted deals get follow-up tasks on the policy's cadence. The pipeline shows every deal's current rep, state, next due date and policy, with filters and CSV export. Managers see workload per rep, override assignments with a reason and every change is kept in a history. Reps see their offers, deals and tasks, with in-app alerts.
- [Dealer Desk](https://vtc.com/apps/dealerdesk) ([Launch](https://dealerdesk.apps.vtc.com)) [Business]: Run your car dealership from one shared desk in your Space. Keep one inventory across branches with VIN, specs, photos, prices, status and days in stock. Book test drives, build deals with offer, discount, trade-in and a documents checklist, and track invoices as Draft, Sent or Paid. The service board takes jobs from Open to Completed with technicians, labour hours, parts and totals. Branch managers see a dashboard and a roll-up across branches, plus reports for inventory aging, sales pipeline, service turnaround and parts usage, with CSV export and print. Staff roles (branch manager, sales rep, service advisor, technician, viewer) control who sees and changes what.
- [Degree audit](https://vtc.com/apps/edudegree) ([Launch](https://edudegree.apps.vtc.com)) [Education]: Helps students understand their progress toward completing a degree or academic program. It compares completed courses and credits against program requirements. Missing requirements and remaining credits are clearly highlighted. Students and advisors can use the information to plan future semesters. The app helps prevent missed requirements and keeps graduation plans on track.
- [DevPilot](https://vtc.com/apps/devpilot) ([Launch](https://devpilot.apps.vtc.com)) [Education]: Your guide from idea to production. The application should ultimately help transform a developer from: "I can write code." into: "I can take a software product from an idea to a reliable production release."
- [Diffraction Grating Simulator](https://vtc.com/apps/diffraction) ([Launch](https://diffraction.apps.vtc.com)) [Education]: Adjust slit width, spacing, and count on a diffraction grating and watch the intensity pattern sharpen from a few blurry interference fringes into crisp, well-resolved spectral lines as you crank up the number of slits. The single-slit diffraction envelope and multi-slit interference pattern are both visible and toggleable separately, so you can see exactly how the envelope suppresses certain interference orders into "missing" lines. A precise, exact-formula simulation of the same effect that splits white light into a rainbow on the back of a CD.
- [Diffusion Mini-Model](https://vtc.com/apps/diffusion) ([Launch](https://diffusion.apps.vtc.com)) [Education]: Train a tiny image diffusion model and watch pure noise resolve into a picture.
- [Digital Assets](https://vtc.com/apps/assets) ([Launch](https://assets.apps.vtc.com)) [Community]: Create, issue and manage unique digital assets on the VTC Ledger, including badges, certificates, collectibles, game items and more.
- [DNA Replication Fork Animator](https://vtc.com/apps/dnareplication) ([Launch](https://dnareplication.apps.vtc.com)) [Education]: Paste in a template sequence and watch a replication fork copy it step by step: helicase unzips the helix, primase lays down primers, and polymerase extends them one base at a time. Because DNA can only be built in one direction, one strand is copied smoothly while the other is made in short Okazaki fragments that are stitched together afterward, and every 5' and 3' end stays labeled so the logic is visible. At the end, the two daughter molecules each show one old and one new strand, the semi-conservative result. Switch between bacterial and eukaryotic enzyme sets and fragment sizes to see what changes.
- [Doc Tracker](https://vtc.com/apps/doctracker) ([Launch](https://doctracker.apps.vtc.com)) [Work]: Track compliance documents with versions, expiry alerts, CSV import/export, and category settings for a VTC space.
- [Docs](https://vtc.com/apps/docs4pcu6q) ([Launch](https://docs4pcu6q.apps.vtc.com)) [Productivity]: A lightweight Markdown editor for creating, editing, and organizing notes or documentation.
- [Donation Drives](https://vtc.com/apps/drives) ([Launch](https://drives.apps.vtc.com)) [Community]: Run fundraising drives for your club, charity, school PTA or community Space. Organisers create drives with a goal and deadline, members pledge online (optionally anonymously) with a message on the donor wall, and organisers mark pledges as received or record offline gifts by cash, bank transfer, cheque or card. Everyone sees live progress towards each goal. Donors get numbered, printable receipts, and organisers get a filterable pledge list with totals, CSV export, an activity log and receipt settings.
- [Doppler Effect Simulator](https://vtc.com/apps/dopplereffect) ([Launch](https://dopplereffect.apps.vtc.com)) [Education]: Watch wavefronts bunch up ahead of a moving source and stretch out behind it, with a live-measured frequency shift at the observer that's derived straight from the animation, not just a formula plugged in separately. Push the source past the wave speed and watch the simulation switch into a proper Mach cone instead of breaking down. Works for both moving sources and moving observers, so you can explore every combination the classic Doppler formula covers.
- [Double Pendulum Chaos Explorer](https://vtc.com/apps/doublependulum) ([Launch](https://doublependulum.apps.vtc.com)) [Education]: A genuinely 3D double pendulum — not constrained to a flat plane like the simpler 2D version elsewhere in this collection — swinging with real out-of-plane freedom. Launch two nearly-identical "twin" pendulums and watch them diverge, with a live-computed Lyapunov exponent putting an actual number on how chaotic the current motion is. Compare a gentle, near-regular low-energy swing against a wildly chaotic high-energy one and watch that number swing from near zero to clearly positive.
- [Double-Slit Quantum Buildup](https://vtc.com/apps/doubleslits) ([Launch](https://doubleslits.apps.vtc.com)) [Education]: Watch individual particles land one at a time on a detection screen, each appearing as a single random point — and watch the same familiar double-slit interference pattern slowly emerge from thousands of those individual dots. A which-path toggle shows the equally famous flip side: if which-slit information becomes available, the interference pattern disappears entirely, replaced by the simple sum of two single-slit patterns. About as close as a browser app gets to actually witnessing wave-particle duality happen in front of you.
- [Dues & Renewals](https://vtc.com/apps/dues) ([Launch](https://dues.apps.vtc.com)) [Community]: Keep track of member dues for your club, society or association Space. Treasurers set membership tiers with a price and renewal period, enrol Space members or name-only members, and see who is paid up, due soon, overdue or lapsed at a glance. Record cash, bank transfer, cheque or card payments, void mistakes, pause or cancel memberships, and print simple receipts. Members see their own membership, renewal date and receipts, and can tell the treasurer they have paid so it can be confirmed or rejected. Includes payment totals, CSV export, an activity log and a grace period setting.
- [Electric Field Line Mapper](https://vtc.com/apps/fieldline) ([Launch](https://fieldline.apps.vtc.com)) [Education]: Drag point charges around a canvas and watch electric field lines and equipotential contours recompute live, always staying perfectly perpendicular to each other everywhere they cross. Switch between field-line view, equipotential view, and a raw vector-arrow grid, or click anywhere to read off the exact field strength and potential at that point. A dipole configuration produces the classic, instantly recognizable field pattern you'd sketch by hand — except this one's exact.
- [Electromagnetic Induction Lab](https://vtc.com/apps/electromagnetic) ([Launch](https://electromagnetic.apps.vtc.com)) [Education]: Drag a bar magnet toward and away from a coil and watch Faraday's law happen in real time: hold the magnet still and the induced EMF reads exactly zero, move it and a genuine EMF appears, computed from the actual rate of change of magnetic flux. The induced current's direction flips correctly depending on whether the magnet approaches or recedes, directly demonstrating Lenz's law. Switch to the rotating-coil generator mode to see where the sinusoidal AC waveform in every wall socket actually comes from.
- [Electromagnetic Wave Visualizer](https://vtc.com/apps/electromagneticwave) ([Launch](https://electromagneticwave.apps.vtc.com)) [Education]: Watch a traveling electromagnetic wave in 3D, with the electric and magnetic field vectors oscillating perpendicular to each other and to the direction of travel, exactly as Maxwell's equations require. Switch between linear, circular, and elliptical polarization, and look straight down the propagation axis to see the polarization state traced out as a line, circle, or ellipse by the field vector's tip. A hands-on way to build real intuition for what "polarization" actually looks like, rather than just a word attached to sunglasses.
- [Electron Config / Orbital Builder](https://vtc.com/apps/orbitalbuilder) ([Launch](https://orbitalbuilder.apps.vtc.com)) [Education]: Builds electron configurations atom-by-atom following the Aufbau principle, Hund's rule, and the known exceptions (chromium, copper, etc.), shown as an interactive orbital box diagram. Includes a "build it yourself" quiz mode and an animated fill sequence.
- [Element Flashcards](https://vtc.com/apps/elementflash) ([Launch](https://elementflash.apps.vtc.com)) [Education]: Procedurally generated flashcards and multiple-choice quizzes on core element facts — symbol, name, atomic number, category, mass — with intelligently plausible wrong answers rather than random filler. A scope filter keeps beginners from being quizzed on obscure superheavy elements.
- [Email Sender](https://vtc.com/apps/emailsender) ([Launch](https://emailsender.apps.vtc.com)) [Business]: Send emails to members, customers, subscribers, employees, or prospects. Create campaigns, manage contact lists, schedule delivery, and track engagement whether you're sending to one person or one million.
- [Embedding Explorer](https://vtc.com/apps/embeddingexplorer) ([Launch](https://embeddingexplorer.apps.vtc.com)) [Education]: Explore a large pre-built word embedding space with analogy math and nearest-neighbor search.
- [Empirical & Molecular Formula Finder](https://vtc.com/apps/empirical) ([Launch](https://empirical.apps.vtc.com)) [Education]: Works backward from percent composition or combustion-analysis data (CO2/H2O masses) to derive empirical and molecular formulas, using a real ratio-search algorithm rather than naive rounding. Hands the result straight to the molar mass calculator for verification.
- [Enrolment](https://vtc.com/apps/eduenrol) ([Launch](https://eduenrol.apps.vtc.com)) [Education]: Manages student enrollment throughout the academic year. Administrators can track applications, approvals, class allocations, and enrollment status. Student records are automatically organized for future academic processes. Digital workflows reduce paperwork and administrative effort. The app ensures a smooth and efficient enrollment experience.
- [Entropy & Microstates Explorer](https://vtc.com/apps/microstates) ([Launch](https://microstates.apps.vtc.com)) [Education]: Count microstates directly for a system of particles split between two boxes, and watch entropy — literally the log of that count — peak sharply at the balanced, half-and-half configuration. Start every particle in one box and let them randomly switch sides one at a time: the system reliably drifts toward and then fluctuates around the balanced state, purely from randomness, no rule forcing it there. Compare small and large particle counts side by side and watch that statistical tendency become dramatically stronger as the numbers grow — a real, hands-on feel for why the second law of thermodynamics holds so reliably at everyday scales.
- [Enzyme Kinetics Lab](https://vtc.com/apps/enzymekinetics) ([Launch](https://enzymekinetics.apps.vtc.com)) [Education]: Explore Michaelis-Menten kinetics with sliders for Vmax and Km and watch the rate curve and its Lineweaver-Burk plot update together, including the telltale line patterns of competitive, noncompetitive and uncompetitive inhibitors. A simulated experiment generates noisy data from hidden values so you can estimate the parameters two ways, by the old double-reciprocal line and by a direct nonlinear fit, and see which does better. An inhibitor-identification exercise lets you work out the mechanism from data, with no scoring or timer. Overview, Standard and Advanced levels adjust how much of the math is shown.
- [Equilibrium Constant Solver](https://vtc.com/apps/equilibrium) ([Launch](https://equilibrium.apps.vtc.com)) [Education]: Solves for K given equilibrium concentrations, or solves for equilibrium amounts given K, complete with a built ICE table and a qualitative Le Chatelier's-principle stress predictor. Handles Kp/Kc conversion too.
- [Equipment](https://vtc.com/apps/equipment) ([Launch](https://equipment.apps.vtc.com)) [Utilities]: Book equipment and assets.
- [Events](https://vtc.com/apps/events) ([Launch](https://events.apps.vtc.com)): Create Events, share them and let users join
- [Exams](https://vtc.com/apps/eduexam) ([Launch](https://eduexam.apps.vtc.com)) [Education]: Streamlines exam scheduling, administration, and result management. Teachers can create assessments and publish exam timetables with ease. Students receive schedules, instructions, and results from one platform. Performance analytics help evaluate learning outcomes after every assessment. The app simplifies the entire examination process.
- [Exoplanet Transit Simulator](https://vtc.com/apps/exoplanet) ([Launch](https://exoplanet.apps.vtc.com)) [Education]: Adjust a planet's size, orbit, and inclination and watch the resulting light curve dip exactly when it should — deeper for a bigger planet, longer for a wider orbit, and not at all once inclination tilts the orbit out of view. A "detect the planet" mode flips the exercise around: given a mystery light curve, adjust sliders until yours matches, then check your recovered parameters against the truth. The same basic technique astronomers actually use to find planets around other stars, made directly interactive.
- [Expense manager](https://vtc.com/apps/expensemanager) ([Launch](https://expensemanager.apps.vtc.com)) [Finance]: Expense Manager is a personal finance application that allows users to track their expenses, income, budgets, accounts, savings, and financial trends in one place. The application also includes a group/event expense management system, allowing multiple users to create an event, add shared expenses, split expenses among participants, track who paid, calculate who owes whom, and settle balances.
- [Expenses](https://vtc.com/apps/expenses) ([Launch](https://expenses.apps.vtc.com)) [Work]: Snap receipts or type them in, submit claims to your Spaces, approve and reimburse with policy flags, and roll up a whole network. AI scan optional.
- [Family Meds Tracker](https://vtc.com/apps/familymeds) ([Launch](https://familymeds.apps.vtc.com)) [Health & Fitness]: Keep every family member's medicines, supplements and health readings in one private place. See today's doses for the whole family, tap Taken or Skip, and get in-app alerts for doses that are due, late or missed. Add each person with allergies, doctor and pharmacy details; set fixed times, every-N-hours or as-needed schedules with stock counts and refill alerts. Simple safety checks flag a shared active ingredient or a possible allergy match. Log blood pressure, glucose, weight, temperature and heart rate, follow adherence on a monthly calendar, and print or export a report for doctor visits. Everything is private to you and follows you across devices. For personal record keeping only; always follow your doctor's or pharmacist's advice.
- [Family Timeline](https://vtc.com/apps/familytimeline) ([Launch](https://familytimeline.apps.vtc.com)) [Lifestyle]: A private timeline of your family's milestones and memories. Add a memory with a title, date, category, place, people, tags, notes and up to six photos, then browse it as a timeline grouped by year and month. Favourite and duplicate memories, search and filter everything, and look back with On this day and upcoming birthdays. Copy a memory as text or print it to share, and export memories to CSV, JSON or a printable PDF. Your timeline is private to you and follows you across Spaces and devices.

- [Linkage & Recombination Mapping Lab](https://vtc.com/apps/linkage) ([Launch](https://linkage.apps.vtc.com)) [Education]: Watch crossovers happen in a simulated meiosis, then use the resulting gamete counts to estimate recombination fractions and convert them to map distances with the Haldane and Kosambi functions. A three-point cross solver walks through finding gene order from the rarest double-crossover class and computing interference, and a LOD score tests whether two genes really are linked. A linkage disequilibrium panel shows how association between loci decays over generations, and three depth levels fit different backgrounds.
- [Lists](https://vtc.com/apps/lists) ([Launch](https://lists.apps.vtc.com)) [Productivity]: Create lists for shopping and...well..whatever else you can think of
- [Live Q&A](https://vtc.com/apps/liveqa) ([Launch](https://liveqa.apps.vtc.com)) [Social]: Let the audience pose questions for you or others to see

Teachers can manage classroom activities and monitor student engagement from one dashboard. The hub supports online, hybrid, and blended learning models. Integration with other educational systems ensures seamless information flow. It creates a connected and efficient digital learning ecosystem.
- [Lorentz Transform Visualizer](https://vtc.com/apps/lorentz) ([Launch](https://lorentz.apps.vtc.com)) [Education]: Place events on a spacetime diagram and watch their coordinates transform between reference frames as you adjust a relative-velocity slider — including the moving frame's own tilted axes, drawn correctly relative to the light cone. The spacetime interval between any two events comes out identical no matter which frame you compute it from, the single defining property of a correct Lorentz transformation, verified live. A light-cone overlay shows which events can causally affect which, and shows how two distant, unconnected events can even swap apparent time-order depending on your frame.
- [Lost & found](https://vtc.com/apps/edulostfound) ([Launch](https://edulostfound.apps.vtc.com)) [Education]: Helps students and staff report, search, and recover lost belongings. Users can upload descriptions and images of found or missing items. Administrators can manage claims and verify ownership before returning items. Search filters make it easy to locate matching records. The app improves recovery rates and keeps the school community informed.

- [Magnetic Field Visualizer](https://vtc.com/apps/magneticfield) ([Launch](https://magneticfield.apps.vtc.com)) [Education]: Explore the magnetic field around a current loop, a solenoid, or a bar magnet in full 3D, with field lines traced directly from the Biot-Savart law rather than approximated. Watch a solenoid's field flatten into the idealized "uniform interior" textbook result as you extend its length, while the field near its ends stays visibly weaker and more spread out — the real end-effect behavior most diagrams skip. A cross-section slice mode gives you a cleaner, more readable 2D map when precision matters more than the full 3D picture.
- [Marketplace](https://vtc.com/apps/classifieds) ([Launch](https://classifieds.apps.vtc.com)) [Shopping]: Marketplace gives every space its own mini-marketplace—fast, simple, and social. Members can instantly post items for sale, offer services, share job openings, or list rentals with just a title, photos, and a price.

- [Members](https://vtc.com/apps/membersdir) ([Launch](https://membersdir.apps.vtc.com)) [Business]: Ai powered Members Directory, can also be used as Employee Directory.
- [Membrane Transport & Membrane Potential Simulator](https://vtc.com/apps/membranetransport) ([Launch](https://membranetransport.apps.vtc.com)) [Education]: Watch particles cross a membrane by simple diffusion, osmosis, carrier-mediated transport and the sodium-potassium pump, with a particle view and a smooth concentration curve side by side so you can see random motion produce predictable averages. Facilitated diffusion saturates while simple diffusion stays linear, and turning the pump off lets the gradients run down. Set the ion concentrations and permeabilities and the app computes Nernst potentials and the resting membrane potential from the Goldman-Hodgkin-Katz equation, showing where a cell's voltage comes from.
- [Mentors](https://vtc.com/apps/mentors) ([Launch](https://mentors.apps.vtc.com)) [Community]: Match members with mentors by shared skills, then track goals and sessions together. Owners run the program, tags and matches.

Members report spam, harassment or other problems, follow their own reports, withdraw them and see messages from moderators. Moderators work a queue with filters, assign reports, add private notes, link related reports and record outcomes. People pages show each member's history, warnings, suspensions and bans with a strike count. Members can appeal sanctions and moderators uphold or overturn them. Every action goes to an audit log with CSV export, and admins set report reasons, strike limits and guidelines.
- [Molar Mass Calculator](https://vtc.com/apps/molarmass) ([Launch](https://molarmass.apps.vtc.com)) [Education]: Type any chemical formula — including nested parentheses and hydrates — and get the molar mass instantly, with a full per-element breakdown and percent composition. Built around a real formula parser rather than pattern matching.
- [Molecular Geometry Visualizer](https://vtc.com/apps/molecular) ([Launch](https://molecular.apps.vtc.com)) [Education]: Predicts and renders 3D molecular shape from electron-domain counting (AXmEn), showing both the idealized electron geometry and the named molecular geometry with correct bond angles. Can take a direct handoff from the Lewis structure drawer.
- [Molecule 3D Viewer](https://vtc.com/apps/molecule3d) ([Launch](https://molecule3d.apps.vtc.com)) [Education]: Renders real molecular structures in 3D from pasted PDB coordinates or SMILES notation, with ball-and-stick and space-filling display styles and a small library of preloaded example molecules. Clearly labels SMILES-derived layouts as approximate rather than a true computed conformer.
- [Movie Ratings](https://vtc.com/apps/movierr2ol) ([Launch](https://movierr2ol.apps.vtc.com)) [Entertainment]: Add ratings for movies you have watched.
- [Mutation Accumulation & Molecular Clock Simulator](https://vtc.com/apps/mutationrate) ([Launch](https://mutationrate.apps.vtc.com)) [Education]: Evolve DNA sequences along two diverging lineages and compare the true number of changes with what you can actually observe, which saturates because of multiple hits at the same site. The Jukes-Cantor and Kimura corrections recover the true distance, and the molecular clock turns that distance into an estimate of when the lineages split. Presets with cited human, bacterial and viral mutation rates ground the numbers, and a calibration tool shows how rate variation across lineages can break a strict clock.
- [My Resto](https://vtc.com/apps/resto) ([Launch](https://resto.apps.vtc.com)) [Food]: Create restaurant menus, share them with customers - Bonus, let users discover your business as well!
- [N-Body Gravity Simulator](https://vtc.com/apps/nbody) ([Launch](https://nbody.apps.vtc.com)) [Education]: Drop bodies onto a canvas, drag to set their velocity, and watch gravity do the rest — including genuinely stable configurations like the famous figure-eight three-body orbit. A leapfrog integrator (not the naive method that makes orbits spiral out over time) keeps energy and angular momentum honest, with live conservation readouts proving it. Try the solar-system-lite preset or build a random cluster and watch it settle into orbits on its own.
- [Nearby](https://vtc.com/apps/nearby) ([Launch](https://nearby.apps.vtc.com)) [Lifestyle]: Find Coupons, rewards, Jobs and other things nearby using your map location

Members can post updates, share resources, start discussions, publish events, and connect with the community. Apps can also share important updates, keeping everything happening in your space organized in one place. Use filters to quickly find the content, people, and activities that matter most.
- [Notes](https://vtc.com/apps/notes) ([Launch](https://notes.apps.vtc.com)) [Productivity]: Create notes, add voice transcripts, make available for the AI to reference for future. Share notes with others. Use as personal or Space app
- [Nuclear Fission Chain Reaction Visualizer](https://vtc.com/apps/nuclearfission) ([Launch](https://nuclearfission.apps.vtc.com)) [Education]: A single slider — the multiplication factor k — controls everything: below 1 the chain reaction visibly dies out, at exactly 1 it settles into the same steady, sustained rate real reactors are actively controlled to maintain, and above 1 it grows explosively. Watch individual fission events branch and cascade across a 2D field of atoms while a live population plot tracks the same trend the particle animation shows. Framed clearly around how control rods keep real nuclear reactors sitting right at that critical k equals 1 point.
- [Observation Journal](https://vtc.com/apps/obsjournal) ([Launch](https://obsjournal.apps.vtc.com)) [Education]: A private journal for classroom observations. Capture a quick note in seconds, by typing or by voice dictation in your browser, and tag it with a student, subject, behavior, strategy and outcome. Pin important notes, mark follow-ups, duplicate and edit notes, and search everything with filters. Reflect shows your week or month at a glance: notes per student, strategies used, outcomes and which strategies worked. Export selected notes to CSV or print them and save as PDF. Customize your subjects, behaviors and strategies in Settings. Your notes are private to you and follow you across Spaces and devices.
- [Offboarding](https://vtc.com/apps/offboarding) ([Launch](https://offboarding.apps.vtc.com)) [Work]: Run every employee exit in one place. HR opens an offboarding case with exit date, manager and interviewer, and a checklist from your templates (return equipment, revoke access, hand-over, documents). The departing employee sees only their own case: they tick off their tasks and book their exit interview from your interview hours, with a calendar file to download. HR and managers track task progress, documents and the interview, keep private feedback and notes the employee never sees, get manager sign-off and close the case. Every change goes in an audit log you can export as CSV, and reports show exits by month, department and reason. Set interview hours, length, lead time and booking window, and give Space members HR, Manager or Viewer roles.
- [Officers & Committees](https://vtc.com/apps/officers) ([Launch](https://officers.apps.vtc.com)) [Community]: Officers & Committees: keep track of who holds which role in your Space. Set up committees and positions such as Chair, Secretary and Treasurer, assign members or named people to terms with start and end dates, and see current, upcoming and past holders on a clear Who's who page. Members see their own roles on My roles with warnings when a term ends soon, and can write handover notes for whoever takes over. Organisers record elections and results and turn them into new terms in one step, end terms early, reorder positions, export terms and activity to CSV and set the welcome message in settings.

- [OneMore](https://vtc.com/apps/onemore) ([Launch](https://onemore.apps.vtc.com)) [Lifestyle]: Things are difficult. You don't have to do everything today. Just take OneMore step. The application should ultimately become a micro-coach for moments of hesitation rather than simply another motivational content library.
- [Optical Fiber Simulator](https://vtc.com/apps/opticalfiber) ([Launch](https://opticalfiber.apps.vtc.com)) [Education]: Launch a light ray into a fiber and watch total internal reflection guide it down the core — or fail to, if the entry angle falls outside the fiber's acceptance cone, in which case the ray visibly leaks out into the cladding instead. The numerical aperture and critical angle are computed live from the core and cladding refractive indices, with the acceptance cone rendered right at the fiber's entrance face so you can see exactly which launch angles will and won't guide. A simplified mode-profile view rounds it out with an illustrative look at what the light's cross-sectional intensity pattern looks like inside.
- [Orbital Mechanics](https://vtc.com/apps/orbitalmechanics) ([Launch](https://orbitalmechanics.apps.vtc.com)) [Education]: Build any Keplerian orbit by dragging its six classical elements — eccentricity, inclination, and the rest — and watch it trace out in full 3D around Earth, Mars, or the Sun. The built-in Hohmann transfer planner computes the delta-v and timing to move a spacecraft between two circular orbits, then animates the burn sequence. A great way to build real intuition for why elliptical orbits speed up near periapsis, without ever touching an equation.
- [Oxidation State Calculator](https://vtc.com/apps/oxidations) ([Launch](https://oxidations.apps.vtc.com)) [Education]: Algorithmically assigns oxidation numbers to every atom in any compound using the real rule hierarchy — including peroxide and OF2 exceptions — rather than a lookup table. Flags compounds where the same element genuinely holds different states at different positions.
- [PaletteShare](https://vtc.com/apps/palette) ([Launch](https://palette.apps.vtc.com)) [Tools]: Create and share color palettes; users can browse, like, and remix palettes made by others.
- [Parent meetings](https://vtc.com/apps/edupta) ([Launch](https://edupta.apps.vtc.com)) [Education]: Makes it easy to schedule and manage parent-teacher meetings. Parents can book available time slots without manual coordination. Teachers can organize appointments and maintain meeting records. Automated reminders reduce missed appointments. The app strengthens communication between schools and families.
- [Parent portal](https://vtc.com/apps/eduparent) ([Launch](https://eduparent.apps.vtc.com)) [Education]: A dedicated platform that keeps parents informed about their child's academic journey. Parents can view attendance, grades, assignments, announcements, and school updates in real time. The portal strengthens communication between families and educators.

- [Parking](https://vtc.com/apps/parking) ([Launch](https://parking.apps.vtc.com)) [Work]: Reserve parking spots by time slot with no double-booking; members check in on arrival, no-shows are released automatically, and admins manage spots and see utilization.
- [Particle Collision Event Simulator](https://vtc.com/apps/particlecollision) ([Launch](https://particlecollision.apps.vtc.com)) [Education]: Set up a particle collision and get a real event-display-style visualization, with total momentum and energy checked and conserved exactly between the "before" and "after" states, computed with genuine relativistic kinematics rather than approximated. An invariant-mass calculator lets you pick a set of outgoing particles and recover the mass of whatever intermediate particle produced them — the same technique real particle physicists use to discover new particles from their decay products. A concrete taste of how collider data is actually read.
- [Pattern Matcher](https://vtc.com/apps/patternmatch) ([Launch](https://patternmatch.apps.vtc.com)) [Education]: Pattern Matcher
- [PCR Amplification Simulator](https://vtc.com/apps/pcramplification) ([Launch](https://pcramplification.apps.vtc.com)) [Education]: Run the thermal cycler and watch DNA double each cycle, tracked strand by strand so you can see when the product of exactly the right length first appears and then takes over. Add a realistic efficiency and a plateau, then switch to a real-time qPCR view and read Ct values from a dilution series, with the slope giving your efficiency. A primer checker reports amplicon length, GC content, melting temperature and common problems like primer dimers.
- [Pedigree Builder & Inheritance Analyzer](https://vtc.com/apps/pedigreebuilder) ([Launch](https://pedigreebuilder.apps.vtc.com)) [Education]: Draw a family pedigree with standard symbols and the app checks it against autosomal dominant and recessive, X-linked, Y-linked and mitochondrial inheritance, listing which patterns remain possible and exactly why the others fail. Mark the affected and unaffected relatives and it works out genotype probabilities for anyone in the chart with the working shown, including the classic result that an unaffected sibling of someone with a recessive condition is a carrier two-thirds of the time. Everything stays in your browser, it uses fictional families, and it is an educational tool, not for clinical use.
- [Peer Reviews](https://vtc.com/apps/peerreviews) ([Launch](https://peerreviews.apps.vtc.com)) [Education]: Run class assignments with a peer-review cycle: rubrics, student submissions, rotating peer reviewers, revisions and instructor grading on a Kanban board.
- [Pendulum Lab](https://vtc.com/apps/pendulumlab) ([Launch](https://pendulumlab.apps.vtc.com)) [Education]: A pendulum simulator covering three modes: a simple pendulum swinging under gravity, a compound pendulum with real moment of inertia, and a full double pendulum for chaos. The simple pendulum uses the actual nonlinear equation, so large swings visibly depart from the "textbook" period formula. The double-pendulum mode includes a side-by-side "twin" comparison, showing two nearly identical starting angles spiraling into totally different motion.
- [Perceptron Playground](https://vtc.com/apps/perceptron) ([Launch](https://perceptron.apps.vtc.com)) [Education]: Trains a tiny neural network from scratch, live, to solve the XOR problem — showing why a single neuron can't do it and why backpropagation was needed.
- [Periodic Table](https://vtc.com/apps/periodictable) ([Launch](https://periodictable.apps.vtc.com)) [Education]: The full 118-element interactive table with search, category/phase filters, and an element detail view featuring a 3D electron-shell and orbital-cloud atom model. The foundation app the rest of the family builds on and links back to.
- [Periodic Trends Visualizer](https://vtc.com/apps/trendsvisualizer) ([Launch](https://trendsvisualizer.apps.vtc.com)) [Education]: The periodic table recolored by a selectable property — electronegativity, atomic radius, ionization energy — so trends across periods and groups become visible at a glance. Includes a comparison mode for putting 2-4 elements side by side.
- [Permits](https://vtc.com/apps/permits) ([Launch](https://permits.apps.vtc.com)) [Work]: Request permits from owner-defined categories, and review, approve or reject them with a permit number and a full status history.
- [pH / Acid-Base Calculator](https://vtc.com/apps/phcalculator) ([Launch](https://phcalculator.apps.vtc.com)) [Education]: Converts instantly between pH, pOH, [H+], and [OH-], and solves weak acid/base equilibrium problems with a full ICE table plus a Henderson-Hasselbalch buffer calculator. Flags when the standard simplifying assumption breaks down and needs the full quadratic.
- [Photo Album](https://vtc.com/apps/album) ([Launch](https://album.apps.vtc.com)) [Social]: Photo Album for pictures and videos
- [Photoelectric Effect Lab](https://vtc.com/apps/photoelectric) ([Launch](https://photoelectric.apps.vtc.com)) [Education]: Shine light of adjustable frequency and intensity on a metal and measure the stopping voltage needed to halt the resulting photocurrent — and discover that intensity changes the current but never the stopping voltage, while frequency does the opposite. Below a threshold frequency, no photoelectrons appear no matter how bright the light gets, the exact result that stumped classical physics. Sweep frequency, record stopping voltage, and fit a line through the data to extract Planck's constant yourself, straight from simulated "experimental" results.
- [Photosynthesis: Light Reactions & Calvin Cycle Simulator](https://vtc.com/apps/photosynthesis) ([Launch](https://photosynthesis.apps.vtc.com)) [Education]: Link the thylakoid reactions to the Calvin cycle in one diagram, with a running ledger of the ATP and NADPH the light reactions make and the amounts the Calvin cycle uses. Slide the light and CO2 controls to see which one limits the rate, and mix cyclic with noncyclic electron flow to change the ATP-to-NADPH balance. A carbon tracker follows three CO2 molecules through one turn of the cycle to a single exported sugar, and the app shows that the released oxygen comes from water.
- [Phylogenetic Tree Builder](https://vtc.com/apps/phylogenetictree) ([Launch](https://phylogenetictree.apps.vtc.com)) [Education]: Build trees from aligned sequences or a distance matrix with UPGMA, Neighbor-Joining and a small exhaustive parsimony search, then test them with bootstrap support. A "known truth" mode evolves sequences along a random tree so you can score each method by how well it recovers the real answer, and a rate-variation demo shows UPGMA failing where Neighbor-Joining holds up. Trees import and export as Newick, and a Robinson-Foulds comparison shows exactly which groupings two trees disagree on.
- [Pickup Scheduler](https://vtc.com/apps/pickup) ([Launch](https://pickup.apps.vtc.com)) [Shopping]: Let customers book a time to collect their order in store. Customers pick a pickup slot from your opening hours (slot length, capacity per slot, lead time and booking window are yours to set), get a pickup code, can reschedule or cancel and tap I'm here when they arrive. Staff work a live pickup queue by day: assign orders, tick items as gathered, mark them ready and hand over with the customer's code or an ID check, with overdue and waiting badges and no-shows after a grace period. Staff can also book walk-in or phone orders. Managers set hours, closed days and capacity changes, give members Staff or Manager roles, and see pickups, no-show rate, wait times, ready-on-time rate, per-staff results, busiest slots and a CSV export. Updates every 15 seconds for everyone in your Space.
- [Pipeline](https://vtc.com/apps/pipeline) ([Launch](https://pipeline.apps.vtc.com)) [Business]: A streamlined sales pipeline app designed to work seamlessly with the Customers CRM module in Posif.

The pipeline automatically links to customer records, giving teams a unified view of every interaction and deal in progress. Ideal for managing sales funnels, improving follow-ups, and keeping the entire team aligned on what needs to happen next.
- [Pitch Deck](https://vtc.com/apps/businessplan) ([Launch](https://businessplan.apps.vtc.com)) [Business]: Pitch Deck is a VTC app that turns a business idea into a Guy Kawasaki 10-slide pitch deck. You describe your idea (plus optional facts), AI drafts all 10 slides in the classic format (problem, solution, magic, team, financials, etc.), then you edit every bullet, add or delete slides, and present the slideshow. Share to public, or as admin in control of your space, share who sees it.
- [Play Partners](https://vtc.com/apps/playpartners) ([Launch](https://playpartners.apps.vtc.com)) [Health & Fitness]: Find racket-sport partners (tennis, padel, pickleball, squash, badminton, table tennis) at your level. Post open games, join or waitlist, record results and attendance with reliability badges, find players by level, venue and time, and embed an open-games widget.
- [Podcasts](https://vtc.com/apps/podcasts) ([Launch](https://podcasts.apps.vtc.com)) [Community]: Community podcast hub for your space: discover, stream, and contribute episodes, save them to your library, and let admins review and feature submissions.
- [Polarization Lab](https://vtc.com/apps/polarizationlab) ([Launch](https://polarizationlab.apps.vtc.com)) [Education]: Stack linear polarizers and watch Malus's law play out live, including the genuinely surprising "three polarizer" trick: two crossed polarizers block all light, but inserting a third one at an angle between them lets some light back through. Add a quarter- or half-wave plate and watch linear polarization transform into circular, or rotate to a new angle, all computed through real Jones-matrix calculus rather than hard-coded special cases. A polarization-ellipse view shows the light's state directly as the shape it traces — a line, a circle, or an ellipse.
- [Policies](https://vtc.com/apps/edupolicy) ([Launch](https://edupolicy.apps.vtc.com)) [Education]: Centralizes school policies, procedures, guidelines, and important institutional documents.

Drag, wind, and spin (the Magnus effect) all bend the trajectory away from the idealized vacuum path, and you can overlay the "no air resistance" version right next to the real one to see exactly how much they diverge. Fire up to four shots at once with different settings to compare range, height, and flight time side by side.
- [Projects](https://vtc.com/apps/projectmanager) ([Launch](https://projectmanager.apps.vtc.com)) [Productivity]: The Project Management app in Posif unifies planning, execution, and collaboration across teams. It connects seamlessly with the CRM suite—Customers, Sales Pipeline, and Tasks—to track deliverables, deadlines, and accountability in one place. In Simple Mode, it offers lightweight tools for startups and freelancers to manage projects efficiently. In Advanced Mode, it unlocks multi-team coordination, milestones, dependencies, Gantt-style views, and time tracking—ideal for larger organizations managing complex workflows.

- [Property](https://vtc.com/apps/propertyspace) ([Launch](https://propertyspace.apps.vtc.com)) [Business]: This is an app spaces to manage their property sales. The app can be forked to modify the UI and functionality while still working with the same data and be able to publish as an option to the Network Property app.
- [Property (Network)](https://vtc.com/apps/property) ([Launch](https://property.apps.vtc.com)) [Lifestyle]: Create your real estate listings, import and export using XML standards. Allow spaces to publish/ubpublish their listings on their own property apps to this network version of Property
- [Protein Folding Simulator (HP Lattice Model)](https://vtc.com/apps/hplattice) ([Launch](https://hplattice.apps.vtc.com)) [Education]: Fold a chain of hydrophobic and polar beads on a grid and watch it collapse into a compact core as a Monte Carlo search hunts for the lowest-energy shape. For short chains the app enumerates every possible fold, so you can see the true best answer and the full landscape of energies, and check the search against it. A folding funnel and a Levinthal's-paradox panel show why a protein doesn't need to try every shape, and a multi-chain mode illustrates misfolding and clumping. It's a deliberately simple toy model, labeled as such, built to teach the ideas behind folding rather than to predict real structures.
- [Purchasing](https://vtc.com/apps/purchasing) ([Launch](https://purchasing.apps.vtc.com)) [Business]: Streamline your procurement process with purchase orders, requisitions, and supplier invoice management. Integrated with Posif CRM, suppliers are managed as customers for unified relationship management.

- [Quantum Tunneling Simulator](https://vtc.com/apps/quantumtunnel) ([Launch](https://quantumtunnel.apps.vtc.com)) [Education]: Watch a wave packet approach a potential barrier and genuinely split — part of it reflects, part of it tunnels straight through, even at energies below the barrier's height where a classical particle simply couldn't pass. The measured transmission probability is checked against the exact closed-form tunneling formula every time, and total probability stays conserved throughout, confirming the simulation is playing by the real rules of quantum mechanics. Widen the barrier and watch transmission drop off sharply — tunneling is famously, exponentially sensitive to exactly how much barrier there is to get through.
- [Quantum Well Solver](https://vtc.com/apps/quantumwell) ([Launch](https://quantumwell.apps.vtc.com)) [Education]: Solve the real time-independent Schrödinger equation for an infinite well, a finite well, or a harmonic oscillator, and watch the resulting energy levels and wavefunctions appear from an actual numerical eigenvalue solve. For the two potentials with exact textbook formulas, the numerically-solved energy levels line up with them almost perfectly — a satisfying, built-in correctness check. Select any level to see its wavefunction, and count its nodes: the ground state has none, the first excited state has exactly one, and so on, exactly as quantum mechanics predicts.
- [Question bank](https://vtc.com/apps/eduquestionbank) ([Launch](https://eduquestionbank.apps.vtc.com)) [Education]: A comprehensive repository of questions categorized by subject, topic, difficulty level, and learning outcomes.

- [Radioactive Decay & Decay Chain Simulator](https://vtc.com/apps/radioactivedecay) ([Launch](https://radioactivedecay.apps.vtc.com)) [Education]: Watch a population of individual atoms decay at genuinely random times, and watch their aggregate survivor count trace out the exact same smooth exponential curve the textbook formula predicts — a direct, visible link between microscopic randomness and macroscopic law. Build a decay chain and watch an intermediate daughter isotope's abundance rise, peak, and fall as it's produced by its parent and destroyed by its own decay in turn. Real decay-chain presets, complete with cited real half-lives, ground the whole thing in actual nuclear physics.

- [Ray Optics Bench](https://vtc.com/apps/rayoptics) ([Launch](https://rayoptics.apps.vtc.com)) [Education]: A classic optical bench, brought to life: drag lenses and mirrors along an axis, place an object, and watch real ray tracing locate the resulting image — real or virtual, upright or inverted, magnified or reduced — using the standard three-ray construction. Chain multiple elements together and watch one lens's image become the next lens's object automatically. A focal-length solver mode works backward too: tell it what image you want, and it tells you what lens you'd need.
- [Reaction Equation Balancer](https://vtc.com/apps/equationbalancer) ([Launch](https://equationbalancer.apps.vtc.com)) [Education]: Paste any unbalanced chemical equation and get it balanced using real linear algebra, not guesswork — handles multi-species combustion and redox equations reliably.

Track contracts with renewal dates, notice deadlines and 30/60/90-day windows, score account health from usage, open tickets and NPS, and run renewal tasks through Owner, Reviewer and Approver hand-offs. The Risk radar ranks open contracts by risk with plain reasons (low usage, open tickets, falling NPS or usage, notice passed), shows a heat map by owner and renewal window, and gives each rep a list of their at-risk accounts. Health history shows trends over time, and reps can log calls, emails, meetings and playbooks with follow-up tasks. In-app alerts flag tasks waiting for you, health warnings and high-risk accounts with no recent outreach; see reports by owner and month and export contracts, tasks and the radar to CSV. Health weights, windows and team lists are set by space admins.

Everyone sees their rides, seats and requests in one place. Organisers can hide or remove posts with a reason, manage the event list, export rides and seat requests to CSV, check stats and an activity log, and set a welcome message and safety note.
- [Rigid Body Rotation](https://vtc.com/apps/rigidbody) ([Launch](https://rigidbody.apps.vtc.com)) [Education]: Spin a box, rod, disc, or asymmetric "book" shape in 3D and watch torque-free rotation do genuinely strange things. The star feature is the tennis racket theorem: spin the asymmetric shape about its intermediate axis and watch stable-looking rotation spontaneously tumble into chaos, a real and famously counterintuitive result. A fixed angular-momentum arrow stays still in space while the object wobbles around it, making the physics visually obvious.
- [Rocket Equation](https://vtc.com/apps/rocketequation) ([Launch](https://rocketequation.apps.vtc.com)) [Education]: Design a multi-stage rocket, budget its delta-v stage by stage using the Tsiolkovsky rocket equation, and then actually launch it in a simulated vertical ascent complete with gravity, thrust, and a simplified atmosphere. Watch staging events happen live as each stage burns out and drops away, with altitude and velocity tracked continuously through the transition. A good way to see why staging matters — and why an underpowered rocket simply won't get off the pad.
- [Rolling vs. Sliding Race](https://vtc.com/apps/rolling) ([Launch](https://rolling.apps.vtc.com)) [Education]: Race a block, a hoop, a solid disc, and both kinds of sphere down the same incline and watch moment of inertia decide the finish order every time. A live "why" panel shows each object's shape factor and resulting acceleration as the race runs, tying the outcome directly back to the underlying formula. Friction only affects the sliding block — rolling objects don't lose energy to kinetic friction, and the race makes that distinction obvious rather than abstract.
- [Room booking](https://vtc.com/apps/edubookings) ([Launch](https://edubookings.apps.vtc.com)) [Education]: Enables staff to reserve classrooms, meeting rooms, laboratories, and shared facilities.

- [StageFlow](https://vtc.com/apps/stageflow) ([Launch](https://stageflow.apps.vtc.com)) [Events]: Run your live shows from one shared cue list in your Space. Stage managers build a run-of-show with timed cues (offsets from show start, durations and dependencies) and assign each cue to a crew role: AV, Lighting, Front of house, Catering, Security or your own roles. During the show everyone sees the cues for their role, with big Ready, Start and Complete buttons, a ticking show clock, late and next-for-you markers and a warning before starting a cue whose dependency isn't done. Updates appear within seconds. Every change is kept in an audit log, and you can print the run-of-show or export it as CSV.
- [Stale Deal Alert](https://vtc.com/apps/staledeal) ([Launch](https://staledeal.apps.vtc.com)) [Work]: Keep your sales pipeline moving. Reps track their deals with a last-activity date, and the app flags every open deal that has gone quiet longer than its stage's limit. Owners get in-app alerts and nudges, deals escalate to managers after a delay, and managers use a Stale deals board to reassign, nudge and comment in bulk. Log calls, emails and meetings to reset the clock, snooze with a reason, mark won or lost, and export open deals to CSV. Stage limits and managers are set by space admins.
- [Stamp Cards](https://vtc.com/apps/stamps) ([Launch](https://stamps.apps.vtc.com)) [Shopping]: Digital stamp cards for cafes, shops and clubs. Members collect stamps by staff QR scan, a daily counter code or a location check-in, then redeem rewards. Analytics and CSV export.
- [Standard Model Particle Explorer](https://vtc.com/apps/standardmodel) ([Launch](https://standardmodel.apps.vtc.com)) [Education]: A browsable, searchable reference chart of every quark, lepton, and boson in the Standard Model, organized by generation and family with real cited mass, charge, and spin values for each.

- [Standing Waves Lab](https://vtc.com/apps/standingwaves) ([Launch](https://standingwaves.apps.vtc.com)) [Education]: See exactly why fixed, free, and mixed boundary conditions on a string produce completely different harmonic patterns — different node counts, different fundamental frequencies, all laid out with labeled nodes and antinodes. Switch to driven mode and sweep a driving frequency across the string's harmonics to watch resonance build up live, with the response peaking sharply right at each harmonic. A direct, visual bridge between the idealized mode-shape diagrams in a textbook and what a driven, damped real string actually does.
- [Status Page](https://vtc.com/apps/statuspage) ([Launch](https://statuspage.apps.vtc.com)) [Work]: Give your Space a status page: list your services as components, report incidents with a timeline of updates, schedule maintenance, and show 90-day history.

- [Stellar Evolution Simulator](https://vtc.com/apps/stellarevolution) ([Launch](https://stellarevolution.apps.vtc.com)) [Education]: Set a star's initial mass and watch it move across the Hertzsprung-Russell diagram through its whole life — protostar, main sequence, red giant, and a final fate determined entirely by that starting mass. Heavier stars burn brighter and die younger, computed from real mass-luminosity and mass-lifetime scaling relations, and every star's ending correctly lands on white dwarf, neutron star, or black hole depending on cited standard mass thresholds. A compact, hands-on way to see why a star's mass is basically its whole destiny.
- [Strange Attractor Viewer](https://vtc.com/apps/strangeattractor) ([Launch](https://strangeattractor.apps.vtc.com)) [Education]: Watch the famous Lorenz butterfly attractor trace itself out in 3D from its classic parameter values, or switch to the Rössler system for its own distinctive spiraling band shape. Launch two trajectories from barely-different starting points and watch them end up in completely different parts of the attractor — deterministic equations producing genuinely unpredictable long-term behavior, the defining signature of chaos. Sweep a key parameter and watch the system visibly cross the line from simple, orderly motion into full chaos.
- [Structured feedback](https://vtc.com/apps/edufeedback) ([Launch](https://edufeedback.apps.vtc.com)) [Education]: Enables teachers to provide clear, organized, and meaningful feedback on student work.

Transcribe with AI, import an .srt or .vtt file, or type the transcript yourself, then fix any word, its timing and emphasis in the word editor. Pick a caption look such as Hormozi Pop or Karaoke Pill, customise font, colours and position, and save brand presets your Space can reuse. Export SRT, VTT, ASS (with karaoke timing) or TXT, or request a captioned MP4. Share projects with your Space so members can view, export or duplicate them.
- [Suggestions](https://vtc.com/apps/suggest) ([Launch](https://suggest.apps.vtc.com)) [Utilities]: Add suggestions, vote or take action on them
- [Superconductivity Demonstrator](https://vtc.com/apps/superconductivity) ([Launch](https://superconductivity.apps.vtc.com)) [Education]: Cool a material down and watch its resistance plummet sharply to zero right at its critical temperature — a real, cited value for an actual superconducting material, not an approximate round number. Below that temperature, the Meissner effect kicks in live: an external magnetic field's lines route around the material instead of penetrating it, flipping the moment the temperature crosses the threshold. A classic magnet-levitation animation caps it off as a visual payoff tied directly to that same field-exclusion effect.
- [Suppliers](https://vtc.com/apps/suppliers) ([Launch](https://suppliers.apps.vtc.com)) [Work]: A shared directory of your space's approved suppliers and vendor contacts, grouped by category, with click-to-call and email links, notes, ratings, pinned favourites and CSV export.

- [Thin Film Interference](https://vtc.com/apps/thinfilm) ([Launch](https://thinfilm.apps.vtc.com)) [Education]: Watch the classic soap-bubble color show up from first principles: sweep film thickness and see the reflected color cycle through the familiar sequence of bands, all computed from actual light interference across the visible spectrum rather than a canned color gradient. Near zero thickness the film correctly goes dark — the same reason a soap film looks black right before it pops. A reflectance-versus-wavelength plot underneath the color patch shows exactly which wavelengths are constructively and destructively interfering to produce what you see.
- [Timeclock](https://vtc.com/apps/timeclock) ([Launch](https://timeclock.apps.vtc.com)) [Work]: Staff clock in and out on their phone with an optional site location check and selfie, take breaks, and submit weekly timesheets.

- [Transformer Simulator](https://vtc.com/apps/transformer) ([Launch](https://transformer.apps.vtc.com)) [Education]: Toggle between an ideal transformer (perfect turns-ratio behavior, zero losses) and a real one where coupling losses, core losses, and winding resistance visibly eat into efficiency. Watch secondary voltage sag below the ideal turns-ratio prediction as you dial up the losses, with a live efficiency readout computed directly from the simulated power flow, not a separate approximated number. A genuinely satisfying way to see exactly where a "real" transformer's output starts to diverge from the textbook ideal case.

Tension and compression members are color-coded so you can see load paths at a glance, with presets for classic Pratt and Warren truss designs. It even checks whether your truss is properly constrained before solving, catching mechanisms and over-constrained structures instead of returning nonsense.
- [Turbulence Visualizer](https://vtc.com/apps/reynoldsnumber) ([Launch](https://reynoldsnumber.apps.vtc.com)) [Education]: A single Reynolds-number slider that sweeps flow around a cylinder through four recognizably distinct regimes — smooth creeping flow, steady separated flow, periodic vortex shedding, and an increasingly irregular wake — each labeled against real, cited reference ranges. Jump straight to a preset example of any regime, or measure the actual vortex-shedding frequency live once it appears. Built on the same fluid solver as the companion flow-simulator app, just with the UI reorganized around the one number that actually determines the flow's character.
- [Turnover Radar](https://vtc.com/apps/turnoverradar) ([Launch](https://turnoverradar.apps.vtc.com)) [Food]: A live table status board for restaurants, cafes and bars.

- [Twin Paradox Simulator](https://vtc.com/apps/twinparadox) ([Launch](https://twinparadox.apps.vtc.com)) [Education]: Watch two twins' worldlines on a spacetime diagram — one straight and inertial, one bent by a turnaround — with each twin's own proper time ticking forward at its own pace as the trip plays out. The traveling twin reliably ages less, and a dedicated explanation panel addresses head-on why this isn't actually a paradox: only the traveling twin's path involves a turnaround, which breaks the naive "it should be symmetric" argument. Adjust travel speed and watch the age gap grow as it approaches the speed of light.
- [Unified portal](https://vtc.com/apps/eduportal) ([Launch](https://eduportal.apps.vtc.com)) [Education]: A single access point that connects all educational tools, services, and resources within the institution.

Managers open a turnover for a unit from a reusable checklist template, with a move-out date and target ready date. Maintenance, Cleaning and Leasing staff see their own tasks in My tasks, start and complete them, skip what isn't needed, add comments and photo links, and log time. Each turnover shows progress and whether it is on track, at risk or overdue, plus a full history. An in-app Inbox tells people when work is assigned, due or ready for the final walkthrough. Manage units and properties, set defaults and roles in Settings, and see average days to ready, on-time rates, bottleneck tasks and staff workload in Reports, with CSV export.
- [Utility Meter Tracker](https://vtc.com/apps/meters) ([Launch](https://meters.apps.vtc.com)) [Business]: Track utility meter readings for a building and bill each unit fairly. Managers set up units, residents and water, gas and electricity meters, open a monthly billing cycle and residents submit their own readings with the previous reading and consumption shown. Unusual readings are flagged against the recent average for review, and lower readings need a meter reset. Managers approve, flag or reject readings, close the cycle, preview the calculation and create per-unit invoices from your tariffs and common charges, then mark them paid. Residents see a due banner, their own invoices and usage charts. CSV export and print. Roles: managers (Space admins plus anyone you add) and residents.

- [Eduslide](https://eduslide.vtc.com) ([VTC Profile](https://vtc.com/networks/eduslide)): Your School. Your Digital Community. Eduslide gives every school its own private social network — a connected digital space for students, teachers, parents and the wider school community. Create a network built around your school, then shape it to fit the way your community works. Bring together classes, clubs, activities, announcements, events, resources, discussions and everyday school life in one secure place. Students can connect and participate. Teachers can communicate, share and manage their communities. Parents can stay informed and involved. Schools remain in control of their own network, membership and experience. More than a school portal Eduslide is designed to become the digital home of your school community. Create spaces for classes, year groups, departments, sports teams, clubs, societies, parent groups and more. Add the apps and tools each community needs, while keeping everything connected under your school's own network. Simple, Usage-Based Pricing Eduslide costs just 1¢ per app, per active hour — regardless of how many students, teachers or parents join, or how many classes, clubs, groups and other spaces your school creates. For example, if your school uses 20 apps for 160 active hours each during a month, your total platform cost would be just $32 for that month. And because Eduslide is usage-based, you don't pay for apps when they're not being used. During school holidays and other quiet periods, unused apps generate no hourly charges — so your costs naturally fall when your school isn't active. No per-user fees. No per-space fees. Just pay for what your school actually uses. One School. One Community. One Network.

## Frequently Asked Questions

### What is the difference between a Space and a Network on VTC?
A Space is a single digital place for a team, community, business, or project with its own website, discussions, and apps. A Network connects multiple Spaces under one umbrella brand and domain.

### How does VTC pricing work?
VTC charges 1¢ ($0.01) per app, per active hour. There are no per-user seats or monthly subscriptions required — you only pay for the hours your apps are actively used.

### Can I use my own custom domain for my Space or Network website?
Yes. Every Space and Network gets a free `<slug>.vtc.com` subdomain and can also connect a custom root domain or subdomain with automatic SSL and full SEO/AIO support (including auto-generated `/sitemap.xml`, `/robots.txt`, and `/llms.txt`).
