Tap a day. A stamp appears. That is the whole app. Calendar Stamp is a sticker chart built on the Calendar app that is already on your iPhone. STAMPS ARE REAL CALENDAR EVENTS Every stamp is saved to the Calendar app as an event. Other calendar apps can see it, it syncs to your other devices through iCloud, and it stays there even if you stop using Calendar Stamp. AS MANY CARDS AS YOU LIKE One card per habit: morning exercise, a walk, brushing your teeth. Pick any SF Symbol or emoji as the stamp, then choose its frame and color. SEE HOW THE MONTH IS GOING Set a monthly goal and the progress appears under the calendar. Count every day, weekdays only, or a fixed number. CHOOSE WHERE IT IS WRITTEN Each card writes to the calendar you pick, so your work calendar stays clean. Stamps can be all-day, or at a fixed time.
