What it does

Your calendar shows every meeting. But the hours you spend at the gym, reading, or doing deep work just disappear. Stamp fixes that. One tap to start a timer, one tap to stop, and a calendar event is created automatically with the exact start and end time. Strava workouts sync on their own. Whoop integration is coming soon. No streaks. No dashboards. No habit tracking. Just your time, visible in your calendar where everything else already lives. Free on iOS. Google Calendar and Outlook supported

Log your activities with a one-tap timer. Stamp creates a calendar event with the exact start and end time — no manual entry, no separate dashboard.

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 fixes that. Log your own activities with a one-tap timer, or connect Strava and let your workouts sync automatically. Either way, Stamp creates a calendar event with the exact start and end time. No manual entry. No separate dashboard. Just your time, in your calendar. Or connect Strava — skip steps 1 and 2 entirely. Finish a run or ride and it goes straight to your calendar. 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…from logwithstamp.app

  • With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
