How it works
Start counting in under a minute
No account, no setup maze. Add a counter and the app does the counting, even while you sleep.
Create a counter
Name the habit, pick a color and set the date you stopped. Started earlier? Backdate it.
Watch it grow
Hours, days, weeks, months or years: switch the unit and see your streak tick live.
Hit milestones
Rings fill toward 1, 3, 7, 14, 30, 60, 90, 180 and 365 days, then 2, 3 and 5 years. Slip up? Log a reset and keep going.
Live counter
See your streak, in the unit that motivates you
26 days feels good. 624 hours feels huge. Switch between hours, days, weeks, months and years and watch the number tick in real time.
This counter is live. Tap a unit to switch, just like in the app.
