Choose an operation and a level, then write your answer on the screen with your finger or Apple Pencil. Answers are checked automatically. Each round has 20 questions.
Tap the answer area once with two fingers to clear it, then write again. Leave a little space between digits. The in-app Write 0–9 guide shows shapes you can try.
Open Settings to change pen colour and thickness, question size, the scratch pad corner, appearance, timer visibility, motion, and effects.
Your fastest times are saved on your device for each mode and level. Settings → Reset lets you erase times or reset settings. Deleting the app removes its local data.
Your practice stays yours

MochiMath does not collect or transmit personal data from the app. No accounts, advertising, tracking, or third-party analytics.
The app stores your settings, fastest round times and results, last-played selection, and recent question history in its private storage. Question history helps reduce repetition. This information is not sent to the developer.
Handwriting recognition runs on your device using a model included with the app. Answer strokes and scratch-pad drawings are temporary and are not sent to us or saved as a handwriting history in the release app.
Settings → Reset lets you clear recorded times or restore settings. These controls do not clear the recent question history. Deleting the app removes the app’s local data. Device backups and restores are managed by your device and Apple account settings.
MochiMath does not request access to your camera, microphone, photos, contacts, or location. Its data practices are the same for all users, including children.
If you choose to email mochimathapp@gmail.com, the developer receives your email address and the message you send, and uses them to respond to your request.
