Good for
- Android users who want a free tracker with no ads and no account
- Logging how a whole day is spent across personal activities
- People who want their time data to stay on their own phone
Worth knowing
- It is an Android app with a Wear OS companion; the project lists no iPhone, desktop or web version.
- Data stays on the phone with no account, so carrying it to another device relies on backup and restore.
- The F-Droid build has no Wear OS support; the watch app needs the Google Play version.
- It is a personal tracker by a single developer, and the listing describes no team, client or invoicing features.
Key features
- One-tap activity timers
- A new activity starts with a single tap from a minimal interface, and earlier records can be reviewed afterwards. The app has screens for categories and tags.
- Statistics
- Statistics show how time was spent over a period, drawn as pie and bar charts, and a detailed statistics screen can be filtered by date.
- Home-screen widgets and notifications
- Widgets track activities straight from the home screen, and the listing also names notifications and a dark mode among the features.
- Goals, reminders and Pomodoro
- Goals have their own screen, and reminders run on custom schedules, including ones for inactivity and untracked time. The app also has a Pomodoro mode.
- Wear OS app
- The Google Play version supports Wear OS watches and provides a watch face complication. The F-Droid build leaves out Google Play services and Wear OS support.
- Backups and CSV export
- The database can be backed up and restored, backups can run automatically, and records export to CSV.
