See your equations take shape.
MathLab is an offline graphing app built for Android. Plot curves as you type, tap anywhere to check the tangent line and slope, and slide numbers to see how formulas change in real time.
Everything you need to explore curves
Fast, responsive, and calculated entirely on your phone without sending any data to the cloud.
Real-Time Graphing
Pinch to zoom and drag to pan. Curves update smoothly as you move, and the app automatically spots asymptotes and jumps.
Live Slope Inspector
Tap anywhere along your function to see the tangent line and check the exact slope f'(x) at that point.
Parameter Playground
Adjust sliders for parabolas, sine waves, and rational functions. See how changing numbers shifts, stretches, or flips the curve.
Baseline Ghost Curves
When you change parameters, a faint ghost curve stays in place so you can easily compare your changes against where you started.
Fast Math Parser
Built from scratch in Kotlin. There is no web browser inside, no heavy runtime, and calculations happen right away.
Works 100% Offline
No internet permission is asked or used. None of your math, device info, or usage habits ever leave your phone.
How it works
Get from a math formula to an intuitive visual in a few quick steps.
Type your equation
Enter any formula using normal math notation. The app supports polynomials, trigonometry, powers, and fractions.
Explore the graph
Pan around, zoom into details, and tap points on the curve to inspect their coordinates and instantaneous slope.
Tweak parameters
Use the sliders in the Playground to see how individual variables stretch or translate your function.
Why MathLab was made
A straightforward tool built for students, teachers, and anyone curious about math.
The idea behind it
Most calculators give you a static number or a clunky chart that feels hard to read. MathLab was made to let you interact directly with math. When you can touch a curve and see it bend as you move a slider, concepts like derivatives and asymptotes become much easier to grasp.
Whether you are working through calculus homework or just reviewing trigonometry, it gives you immediate answers you can see.
How it is built
MathLab is a native Android app written in Kotlin using Jetpack Compose. Graphics are drawn directly with the phone's hardware canvas for a smooth 60fps experience that does not drain your battery.

1. Overview
We built MathLab to be simple, fast, and completely private. You do not need to create an account to use the app, and your mathematical work never leaves your phone.
2. What We Do Not Collect
We do not collect any personal information. We do not ask for your name, email, phone number, contacts, or location. We do not request access to your files, photos, camera, or microphone. There are no accounts or profiles.
3. Your Formulas Stay on Your Phone
Every equation you enter, parameter slider you adjust, and curve you plot is calculated 100% locally on your phone's processor. None of your mathematical work is ever uploaded to any server or stored in the cloud.
4. Ads and Google AdMob
MathLab is free to use and supported by ads from Google AdMob. You can optionally watch a short video ad to unlock a Pro Pass for 4.5 days (108 hours), which turns off all ads across the app and unlocks all visual themes.
Google AdMob may process your device's Advertising ID and basic diagnostic information to prevent fraud and avoid showing repetitive ads. You can reset or delete your Advertising ID anytime in your phone settings under Settings → Google → Ads.
5. What Is Saved on Your Device
The only information saved locally on your phone is your chosen visual theme and the expiration timer for your 4.5-day Pro Pass. This is kept in private app storage on your device and is never uploaded anywhere.
6. Children's Privacy
MathLab is safe for students and users of all ages. Because all calculations run offline on your device and no personal data is collected, MathLab complies with standard privacy regulations, including COPPA and GDPR.

1. Welcome to MathLab
By downloading, opening, or using MathLab, you agree to these Terms of Service. If you do not agree, please uninstall and do not use the app.
2. About MathLab
MathLab is a mobile graphing calculator built by 2uduDev for Android devices. It lets you plot equations, explore slopes, test parameters with sliders, and visualize mathematical curves in real time.
3. Built for Learning, Not Critical Engineering
MathLab is made for studying, teaching, and exploring mathematics. While we work hard to ensure calculations are accurate, computers have precision limits and bugs can occur.
Please do not use MathLab for mission-critical tasks like building design, structural engineering, aviation, medical decisions, or financial calculations. The app is provided as-is without warranties of any kind, and 2uduDev is not responsible for errors or decisions made using the app.
4. Your Formulas Stay on Your Phone
All formulas, numbers, and graphs are processed 100% locally on your phone. None of your math is ever uploaded, shared, or stored on external servers. You do not need an account or login to use MathLab.
5. Ads and the Pro Pass
MathLab is free to use and supported by ads from Google AdMob. You can optionally watch a short video ad to unlock a Pro Pass for 4.5 days (108 hours), which removes ads and unlocks all visual themes. This pass is a temporary virtual perk within the app. It has no cash value and cannot be sold, transferred, refunded, or exchanged for real money.
6. Fair Use
Please use MathLab fairly. Do not attempt to reverse-engineer, copy, modify, or redistribute the app, and do not use automated tools or bots to tamper with ads or pass timers.
