If you have ever stared at a maths formula and thought "I understand the symbols but not the idea", MathVis was built for you. MathVis is a free, progressive web app that turns every important maths formula into an interactive, visual experience — no textbook can do that.
What is MathVis?
MathVis is a free maths formula library and learning tool designed specifically for Indian students following CBSE, ICSE, and State Board curricula. It covers formulas from Class 1 basic addition all the way to PhD-level calculus and linear algebra. Every single formula comes with:
- Visual explanation — animated diagrams and sliders that show the formula in action
- Step-by-step derivation — how the formula is derived, not just what it is
- Interactive solver — enter your known values and get a worked solution
- Quiz — test your understanding with targeted questions
- Tricks and shortcuts — mental maths, Vedic maths, and exam shortcuts
- Real-world examples — using Indian contexts (₹, cricket, familiar places)
- Curated videos — handpicked from trusted sources
Why MathVis Is Different from Other Maths Apps
Most maths apps either give you a list of formulas (a digital textbook) or a problem solver (a calculator). MathVis is neither. It sits in between — it explains why a formula works through visuals, then helps you apply it through the solver. This is the gap no other free Indian maths app fills.

Who Is MathVis For?
MathVis is for every student on the Indian education ladder:
- Class 1-5: Basic arithmetic, fractions, measurement, geometry and data handling
- Class 6-8: Algebra, ratio, proportion, speed-distance-time, basic statistics
- Class 9-10: Quadratic equations, Pythagoras, trigonometry, circles, surface area, probability
- Class 11-12: Calculus, complex numbers, matrices, statistics, permutations
- Graduation and beyond: Advanced calculus, linear algebra, probability distributions, Euler's identity
How to Use MathVis for Maximum Benefit
- Open the app and search for the formula you are studying (e.g. "quadratic formula")
- Read the explanation in plain language — no jargon
- Try the visual — drag the sliders and see how the formula responds
- Watch the derivation — step through where the formula comes from
- Use the solver for your actual homework problem
- Take the quiz to test yourself before moving on
- Check the tricks tab for Vedic maths and mental maths shortcuts for exams
MathVis Works Offline
MathVis is a Progressive Web App (PWA). That means once you have loaded it once on your device, it works completely offline — no internet needed. This is crucial in India where connectivity can be unreliable, especially during late-night exam preparation or in rural areas.
How to Install MathVis on Your Phone
No app store needed. Open postlister.com/mathvis in Chrome on Android, tap the three-dot menu, and choose "Add to Home Screen". On iOS, open in Safari, tap the Share icon, and choose "Add to Home Screen". MathVis will appear like a native app on your phone — and it works offline.
What Makes Indian Students Love MathVis?
The real-world examples use contexts Indian students actually recognise: rupees, cricket averages, IRCTC journeys, Indian cities, and CBSE exam patterns. Every example feels relevant, not lifted from a foreign textbook.
