500,000 downloads. Six years of daily check-ins. One tap, no app launch. DayStamp turns every day you show up into a stamp on your calendar — and puts that calendar where you already look: your Home Screen, your Lock Screen, and your Apple Watch. Drink a liter of water, study for 30 minutes, stretch before work. Tap once. Watch the stamps pile up. WHY PEOPLE STAY FOR YEARS • Check in from a widget. No launching the app, no friction, no excuse. • Your week on the Lock Screen. The Weekly Report widget shows how the week is going before you unlock. • Apple Watch. Tap your wrist and the stamp lands. • Ask Siri. "Check in Running." Done. • Miss a day without breaking.
