Simple calendar & heatmap
Mark what you did and see the pattern build — a calendar and a heatmap, no streak to break. Habits stay on your phone, with no account.
- One tap marks a habit done, a second tap clears it — add a value when minutes or pages matter
- A month calendar that fills in as your days do, and a heatmap for every habit side by side
- Reminders only on scheduled days; skip a day without it counting against you
