How to use the app

Solve a problem: type a problem (e.g. x^2 + 5x + 6 = 0) and tap Solve — you'll get the full worked steps, shown the USA way and the Japan way, checked by a computer algebra system.
Teach mode: tap Teach me to enter each step yourself and have the app check your work with hints.
Practice: tap Practice for generated problems with mastery tracking.
Photo / Graph: snap a photo of problems or a graph to turn it into something the app can solve.

Common questions

Does it work offline? Yes — typed problems are solved entirely on your device; nothing is sent to a server to solve them.
Do I need an account? No account is required.
Is my data private? Yes — see our Privacy Policy. Typed math never leaves your device.
An answer looks wrong / a problem won't solve? Email us the exact problem text and we'll fix it.

Feedback & bug reports

Found a bug or have a feature request? Email addsup.app@gmail.com with a short description (and the problem text or a screenshot if relevant) and we'll take a look.
