Unmissable: Calendar Alarm

Turn calendar events into real system alarms on the Lock Screen and Dynamic Island. One-time purchase, no subscription.

Never miss an important event because of a silent notification.

Unmissable turns your calendar events into real system alarms - the kind that ring clearly when ordinary notifications are easy to miss. It is built for meetings, appointments, calls, classes, and anything you do not want to forget.

REAL ALARMS FOR CALENDAR EVENTS Choose any upcoming event and set a real alarm with one tap. The alarm can ring at the event time or a few minutes before, with snooze and an optional pre-alarm countdown.
