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.

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.

I say it’s niche, because not a lot of people like to track every thing throughout their day, however, I am someone who likes to visually see what I’ve done day in and day out. The best part is I use whoop and it seamlessly syncs with it to update my Google Calendar which is where I post everything on to keep track of what I’ve done. I like to make sure that I’m maximizing my time effectively and knowing where I can remove some fluff/down time and refocus into family, friends, hobbies etc. Honestly if you are someone who likes to also visually keep track of your dad and already have whoop/strava/etc and a calendar and are tired of manually having to log everything in your calendar. Give this app a shot and the best part is it’s free and no ads. The developer is also very very responsive and open to feedback. I had gave some feedback on a feature I thought would be beneficial and within the day he had already implemented it. Great great customer support and excited to see what other unique things come from the app! **Developer response:** Thank you so much for this. You described exactly the problem I built Stamp to solve, so it means a lot that it's clicking for you. The Whoop + Google Calendar combo is one of my favourite parts of the app too, and I'm glad it's working seamlessly for you. Feedback like yours is what keeps me motivated to keep building, so thank you for sharing it here. More good stuff coming! ## Frequently asked questions about Stamp ### Does Stamp have ads?
