The half-minute beat is the most-searched of all, and the easiest to plan around: twice a minute it marks a drill station, a thirty-second physio hold, a posture or position change, or a count called out while your attention is elsewhere. It keeps the half-minute honest so you do not have to track it.
Each round here is two half-minute beats, so ten rounds is ten minutes out of the box — raise the rounds in the editor for a full session, or drop them for a short set.
A roomy beep every 20 seconds, three to the minute, for paced drills, holds, and steps in a process. Loops in your browser, no install.
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.
