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

Earned

Every unlock begins with a commitment. Earned helps you break the scroll-first habit. Before you open the apps you love, you do something that matters — wash the dishes, read, work out, study — and only then earn a limited window of screen time. HOW IT WORKS 1. DECLARE A TASK Choose from dozens of built-in tasks across chores, wellness, learning, creativity, and more — or create your own with Earned Pro. 2. SET A TIMER Pick how long you'll focus. The timer cannot be paused or skipped. Your selected apps stay locked until time is up. 3. EARN YOUR APPS When the timer ends, you unlock a scroll window — screen time you've actually earned. When it's over, apps lock again until your next task. WHY EARNED IS DIFFERENT • Commitment-first — scrolling is the reward, not the default • No pause, no override — the timer runs until it's done • Real tasks, real streaks — build momentum day after day • Uses Apple's Screen Time APIs — locking happens on your device • Widgets & Live Activities — see your timer and progress at a glance FREE INCLUDES • Lock up to 3 apps • 1 app folder • Full task library • Streak tracking • Scroll window after each completed task EARNED PRO • Unlimited app locking • Unlimited app folders • Custom tasks & durations • Schedule tasks ahead of time • Full insights & streak history • Custom scroll window length PRIVACY Earned uses Apple's Screen Time and Family Controls frameworks to lock and unlock apps on your device. We do not sell your data. Screen Time usage data stays on your device. SUBSCRIPTIONS Earned Pro is available as a monthly or yearly auto-renewing subscription. Payment is charged to your Apple ID at confirmation. Subscription renews automatically unless canceled at least 24 hours before the end of the current period.
