Focus. Track. Restore safely.

IsotopeAI runs on your own device. It helps with focus sessions, tasks, subjects, habits, exams, tests, and study stats. Supabase adds login, backup, restore, avatars, and groups.

One command on Android.

Use Termux from F-Droid or GitHub. Do not use the old Play Store build.

bash <(curl -fsSL https://raw.githubusercontent.com/Suydev/isotope-code/main/install-termux.sh)

One backup rule.

If this device has no study data and cloud has a rich backup, upload is blocked until restore succeeds.
