EulerPad is a math practice workspace for iPhone and iPad. Pick a problem, work it out in your own handwriting, and tap Check — EulerPad's AI tutor reads your work and responds the way a good teacher would: what you got right, where a step went wrong, and what to try next. WRITE IT — ON SCREEN OR ON PAPER Math is learned by hand. EulerPad keeps the paper feel — a full-screen canvas, real ink, your own handwriting with Apple Pencil or your finger — and now works with actual paper too: solve it in your notebook, photograph it, and get the same read. Switch between the two whenever you like. Either way, you get the thing paper can't do on its own: feedback on your work itself, not just your final answer. FEEDBACK THAT TEACHES • Your whole solution is read, step by step — not just the answer • Feedback points to the exact step where things went off track • Mathematical notation is typeset cleanly, like a textbook • Still stuck? See a full worked solution A CURRICULUM THAT GROWS Practice Algebra, Geometry, Trigonometry, Calculus, and more, with new problems and topics arriving all the time — no app update required. YOUR OWN PROBLEMS Working from a textbook or worksheet? Bring the problem with you: type it in and solve it the same way, on screen or on paper, with the same feedback. FREE TO PRACTICE Every account includes a free daily practice allowance. EulerPad Premium, an auto-renewing subscription, raises it for heavier practice — manage or cancel anytime in Settings. PRIVATE BY DEFAULT No sign-up required — open the app and start solving. Sign in with Apple only when you want your work and credits to follow you to another device. Made for iPad and Apple Pencil. Now in your pocket, too. Terms of Service: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy: https://eulerpad-2d8dac.gitlab.io/privacy.html
