Three-quarters of a minute is the beat for longer work: a drawn-out hold, a drill round that needs the better part of a minute, or a process step you do not want to cut short. It calls the change out loud so you can keep going and let the timer watch the clock.
Forty-five seconds suits the holds and rounds that thirty rushes — long stretches, slow breathing sets, anything that wants room. Set a handful of rounds for a short block, or many for a long one.
When thirty seconds is too short and a minute too long — a beep every 40 seconds, on repeat, for holds, drill rounds, and station rotations.
A once-a-minute pulse — a beep every minute, on repeat, for pacing exam questions, pages, or drill stations by the clock. Free in any browser, no sign-up.
