Ten minutes is the rotation beat: often enough to move a classroom from one station to the next, glance at the oven, or look up and reset your posture, but spaced enough that it never tips into nagging. One clean beep marks each ten-minute mark, so the task keeps its rhythm and nobody has to watch the clock.
It sits between the frequent five-minute nudge and the calmer quarter-hour — the setting for work that comes in ten-minute chunks. Twelve reminders fill two hours out of the box; raise the rounds in the editor to carry it across a longer session.
A frequent five-minute nudge to look up, stretch, or check progress — a beep every 5 minutes, on repeat, for a desk or a classroom. Runs in your browser, no install.
A calmer quarter-hour beat — a beep every 15 minutes, on repeat, to stretch, sip, or check in at a desk or in class. Free in your browser, no sign-up.
