Track daily habits with a 30-day check-in grid. Monitor streaks, completion rates, and build consistency. Data saved locally — no signup required.
A habit tracker is a tool for monitoring daily behaviors over time. By marking completions on a grid, users build streaks, identify patterns, and increase consistency through visual accountability.
Exercise
| Phase | Days | What to Expect |
|---|---|---|
| Initiation | 1-7 | High motivation, requires conscious effort |
| Struggle | 8-21 | Motivation dips, resistance peaks |
| Consistency | 22-40 | Becoming routine, less willpower needed |
| Stabilization | 41-66 | Near-automatic, occasional lapses OK |
| Automaticity | 66+ | Feels natural, integrated into routine |
Formula
Completion Rate = (Days Completed ÷ Total Days) × 100Days Completed = number of days the habit was successfully completed
Total Days = total number of days in the tracking period (30 days)
Worked Example
Exercise habit over 30 days
Did you know? A 2009 study published in the European Journal of Social Psychology found that it takes an average of 66 days to form a new habit, with a range of 18-254 days depending on the complexity of the behavior.
