YAHT
YAHT (Yet Another Habit Tracker) is free and open-source. It runs entirely on your phone. There are no accounts, no ads, no trackers, and no servers.
YAHT is licensed under the GNU General Public License v3. We do not collect any data. Everything lives on your phone — there is no server. Export and import your habits freely; they are yours.
No clutter, no feature bloat — just your routines.
Track simple yes/no checkmarks, counters (like cups of water), or timed routines with an integrated stopwatch.
Set an exact alarm per habit, with optional follow-up nags spaced however you like. Snooze or mark habits done right from the notification.
See your completion history, streaks, and habits over time. All stats are calculated locally on your device.
No signups or cloud accounts. Export your data to a JSON backup file or import it back with one tap.
Pick warm Sepia tones, clear blue-grays, or a pure black OLED dark mode — each with light and dark variants.
Notifications fire even when the app is fully closed, and timezone correction keeps them on schedule when you travel.
