What you get
Built for people who keep resetting
Your days pile up as grass
One square for each clean day, like a GitHub contribution graph. Tap "Held on" when you beat an urge and today's square gets darker.
A reset doesn't wipe your total
Your streak goes back to 0, but your total days and longest streak stay. The screen after a reset has no blame and no red.
Your streak, in sight every day
Put your streak and power on your iPhone home screen with a widget. The reasons you chose show up when you need them, and milestones come as notifications.
An optional ranking
Compare your power on "All time" and "This week" boards. No account, and you can join privately.
Day 0 again doesn'tmean starting from nothing.
Growth
A koi that grows into a dragon
Your koi grows with your total days across all your habits. A reset never lowers its stage, so the koi keeps growing even when you slip.
