Stamp logs them as calendar events automatically, so your calendar finally reflects your whole day. STAMP IS NOT A HABIT TRACKER No streaks. No check-ins. No badges. Stamp is a calendar tool — specifically the write layer that calendar apps have always been missing. It does one thing and does it well. HOW IT WORKS Log anything with a one-tap timer. Tap start when you begin, tap stop when you're done — the session appears in your calendar with the exact start and end time. Connect Strava and workouts go straight to your calendar the moment you finish a run or ride, no timer needed. Connect Whoop and your sleep sessions, workouts, and a daily recovery summary with HRV and recovery score appear in your calendar automatically every day.
