One tap, instant reward
Every check-in pops XP, grows your flame and pushes you toward the next level. Longer streaks earn more per tap.
A habit tracker you won’t quit
Don’t break the chain.
One tap a day. Watch the streak climb, the flame grow and the chain fill in. Miss a day and the streak resets — but your progress toward a habit that sticks doesn’t.

Milestones worth chasing
3, 7, 14, 30, 100, 365. Each one lands with a celebration, and the next one is always in sight.
A countdown to automatic
Every daily habit counts down to 66 days practised — the median time for a habit to feel automatic in the research.
Perfect days
Finish every daily habit and the day turns gold. Chain perfect days together for the streak that matters most.
What the research says
Forget 21 days. Think 66.
In one well-known study, it took a median of 66 days for a daily habit to feel automatic — and anywhere from 18 to 254 days depending on the person.

Researchers found that missing a single day “did not materially affect the habit formation process.” So in Unbroken a miss resets your streak, but never your progress toward 66.
