Often enough to break a long stretch of screen time, a five-minute reminder prompts a posture reset, a sip of water, or a class moving on to the next short task — frequent without tipping into background noise. One clean beep marks each five-minute mark so nobody has to watch the clock.
In a classroom it keeps short tasks moving; at a desk it is the beat for when you want nudging often rather than left alone for half an hour. Twelve reminders fill an hour out of the box — stretch or trim the run in the editor to fit the session.
