This timer draws 12 minutes as 20 concentric rings; one empties every 36 seconds, so a glance shows how far along you are without reading a digit. It chimes at zero, keeps counting in a background tab, runs fullscreen, and exports as a free MP4 video. Handy for a Cooper run test, a tray of drop cookies, or a quick yoga flow.
Twelve minutes is a fitness test, a tray of cookies, and a short yoga flow. It divides well, which is why routines like it: four threes, three fours, six twos. The dial drops a ring every thirty-six seconds; five rings is three minutes, so the quarter marks of the face are also the three-minute marks.
Kenneth Cooper published the twelve-minute run test in 1968 as a field estimate of aerobic fitness: run as far as you can in twelve minutes on a track or measured route, and the distance is the score. It is still used by clubs, schools, and some services because it needs nothing but a stopwatch and a flat loop. This dial does the stopwatch part. Start it on the first stride, and the chime marks where to stop and pace out the distance. Rerun it in a month on the same loop and compare.
A standard tray of drop cookies, chocolate chip or oatmeal, bakes in ten to twelve minutes at a moderate oven. Twelve gives set edges and a soft centre; a minute or two less keeps them softer still. Start the dial as the tray goes in and rotate it at ring ten if your oven has a hot side.
A twelve-minute yoga flow fits neatly as four three-minute sections: a minute or two of breathing, sun salutations, a couple of standing poses each side, and a rest on the mat. Switch sections at every fifth ring. The rings are silent, so nothing breaks the pace.
Twelve minutes is four boxing rounds back to back, or two of the 6 minute stretch routines, or three Tabata blocks with no gap between them. If you want the gaps, run the shorter dial and restart it.
The 11 minute dial covers a three-round bout with rests; the 13 minute dial is where baked salmon lands. There is a twelve-minute video on the card, and the timers page has every length.
36 seconds. The dial always has 20 rings, and this timer runs 12 minutes.

A radial timer draws the countdown as 20 concentric rings, one for each twentieth of the duration. Rings empty one by one, outermost first, so a glance shows how far along you are without reading a digit.
The timers here are free online countdown timers. Run several at once, take one fullscreen, or pop one out picture-in-picture to float over other apps. Each chimes at zero and keeps counting in a background tab. Any timer exports as a video.
Yes. The countdown follows the clock, so it stays on time while you work in another tab and still chimes at zero. The picture-in-picture popout keeps a small dial in view the whole way.
Yes. Any timer exports as an MP4 or a transparent WebM of the whole countdown, up to 4K and 60 fps, in 16:9, vertical, or square.
Yes. In OBS, add a browser source pointing at radialtimers.com/overlay?t=25m and a transparent dial counts down over your scene. Change t for any length, like 90s or 3h.
As many as you need. Each timer gets its own dial and runs on its own, which suits interval workouts, several dishes on the stove, or a room of activity stations.
