Time Tracker
A time tracker with no account and no server: the data never leaves the phone, and the calendar is optional.
Local-first
No account to create, no backend to trust, nothing collected. The time entries live on the device and stay there.
Google Calendar sync is there if you want tracked time to show up as events, and it is entirely optional — leave it off and everything else works exactly the same.
What it does
Tasks with colours, grouped into categories, switched in seconds. Then the part that made it worth writing: breakdowns and graphs you can filter by task and read across days, weeks, months or years.
On the store
Release 1.0, PEGI 3. Still early — ten-odd installs.
