Habit
Most habit trackers I tried fell into one of two camps: bloated with streak-gamification and social features I didn’t want, or so bare-bones that logging a habit took more taps than it should. Habit is my attempt at the narrow middle ground — log a habit in one interaction, see your history at a glance, and nothing else competing for attention.
Keeping the feature set intentionally small was the actual design challenge here — it’s easier to keep adding things than to leave a tracker this simple.
