Sprout is a small, open-source habit tracker for Android. It keeps your habits and notes on your phone, works without an account, and the APK is under 3 MB.

Each day, every habit is done, partly done (with an amount such as 15 of 20 pages) or skipped. Swipe right to mark a habit done, swipe left to skip it, tap its circle to toggle it, or press and hold to log an amount and add a note. Swiping the other way undoes a swipe. Days you skip are left out of your score, so one bad day doesn't sink the week.
You can also:
- see each week at a glance, or the last 26 weeks as a heatmap, with scores and streaks
- keep a Journal of short notes tied to a habit and a day, filtered by habit or by dates
- look back at any date range in Insights, for all habits or a few, with each habit ranked by score or by streak
- get a reminder at the time you pick, and a nudge in the evening to add a note when you skip a habit that asks for one
- add four home-screen widgets that stay in sync with the app; the Today widget marks habits done from the home screen
- export everything, including your settings, to a JSON file and import it again, or export a CSV for spreadsheets
- choose light or dark, dynamic color from your wallpaper or an accent color, one of five fonts and a text size
- use it in English, Hindi, Spanish, German, French, Portuguese (Brazil) or Japanese, separately from the phone's language

You need JDK 17 or later and the Android SDK (API 36).

Sprout is free and has no ads. I build it because I enjoy it. If it helps you, you can sponsor me on GitHub or star the repo.
