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.
