PRODUCT OVERVIEW

More than a simple daily checklist.

Traditional habit trackers focus strictly on daily streaks. DayPulse expands this concept by allowing users to track meaningful personal events, long-term journeys, recurring habits, and life achievements. The app automatically calculates elapsed time since an event began.

Elapsed Time Accuracy: Precise time-passed calculations running efficiently across growing milestone history.
