Daily Habit Grid
Track daily habits with a twelve-week activity grid. Record counts, correct past days and see active-day streaks without losing your history.
How can I track daily habits in a calendar grid?
Add a habit and an optional daily target. Record a count for today or select any grid cell to correct a past day. Darker cells show more activity relative to your target, or to a typical active day when no target is set. Streaks count consecutive days with at least one recorded activity; an unfinished today does not break yesterday’s streak.
Build a picture of your days. Add a habit below, then record what you did. Every active day counts toward your streak.
