Stamp - Calendar Logger Your calendar shows every meeting. But where did the rest of your day go? The hours you spent reading, studying, or at the gym — they just disappear. 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. KEY FEATURES One-tap start/stop timer per activity Strava integration — workouts sync to your calendar automatically when you finish Whoop integration — sleep sessions, workout activities and daily recovery summary with HRV and recovery score sync automatically Connects to Apple, Google, and Outlook Calendar Customize activities with names and colors Adjust session times and add a note before saving Live Activity on the Lock Screen and Dynamic Island while a session is running Timer keeps running if you leave the app Session history — last 30 days at a glance, with links back to Strava and Whoop activities Works offline — sessions sync to your calendar when you reconnect
