Count the days since — or until — any event, right on your wrist.

Full description:
Days Since turns your watch into a simple, no-fuss day counter. Pick a name and a date for an event, and your watch shows "DAYS SINCE" (or "DAYS UNTIL," if the date's in the future) with a live count that updates automatically every day.

Set up to 8 counters at once — track a work anniversary, a habit streak, a countdown to a trip, whatever matters to you — and cycle between them right on the watch with the Up and Down buttons. No phone required once it's set up.

Features:

Up to 8 independent counters
Easy date picker in settings — no fiddly typing
Counts up automatically, or down for future dates
Cycle through counters with Up/Down
Works fully offline, updates once a day
