Hey PH 👋
I’ve always been obsessed with tracking my time and staying organised. A few years ago when I was trying to build better habits around exercise I made a simple tool to connect my Strava account with my Outlook calendar so my workouts were visible alongside my workday. It changed how consistent I was.
More recently when I was trying to read more frequently I wanted the same thing, to see my reading time in my calendar. That’s when I realised I kept solving the same problem and decided to build it properly.
The core idea is simple. Your calendar shows every meeting and appointment but the time you actually choose to spend on things, the gym, reading, studying, deep work, just disappears. Stamp fixes that. One tap to start a timer, one tap to stop, and it creates a calendar event automatically. Strava syncs on its own and Whoop integration is coming soon for Sleep and Recovery data as well as daily summaries placed right into your calendar.
It started as something I built purely for myself. Once I had it I couldn’t imagine not having it, so I polished it up and put it on the App Store.
Free to download on iOS. Would love to hear what you think and genuinely open to feedback on where to take it next.
