This timer draws 1 minute as 20 concentric rings; one empties every 3 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 minute of box breathing, a wall sit, or a stretch between tasks.
A minute is the smallest unit most people plan with. Nobody schedules forty seconds, but everyone knows what "give me a minute" means. On the dial, one minute is twenty rings at three seconds each: quick enough to see moving, slow enough to read at a glance. The 60 second page is the same length aimed at exercise; this one is for the other uses.
Box breathing is four equal sides: inhale, hold, exhale, hold. At five seconds a side, one box is twenty seconds, so a minute holds three complete boxes with nothing left over. Count each side against the rings if it helps, since five seconds is not quite two rings. At four seconds a side you get three boxes and a spare twelve seconds, which is fine too.
A minute is long enough to stand up, roll your shoulders back, look at something far away, and sit down again. Treat it as a hinge between two pieces of work rather than a break: start the dial the moment one thing ends, and the chime opens the next thing. Done a few times a day, the minute costs almost nothing and stops one task bleeding into the next.
Two minutes is the full recommended brush, but a minute is a fair starter target for small kids and for a midday brush at work. The toothbrush timer page is this same minute with instructions for splitting it into four corners of the mouth; when the habit holds, the 2 minute dial is the next step.
Remembrance ceremonies and school assemblies keep a minute's silence, and the person leading it needs a clock they can see without looking at a wristwatch. Fullscreen the dial on a laptop and the rings do the timing; the double chime at the end can be muted if the silence should end with a spoken word instead.
Ninety seconds is the next common length for rests and microwave jobs, and the 90 second dial covers it. The whole range is listed on the timers page.
3 seconds. The dial always has 20 rings, and this timer runs 1 minute.
Yes. The nearest pages are the 30 second timer and the 2 minute timer, and the custom field on any dial takes an exact length.
Add it as a browser source in OBS; the background stays transparent. Change t for any length.
A radial timer is a free online countdown timer you set in one click: pick a length, press Start, and an alarm sounds at zero. Run several timers at once, take one fullscreen, or pop one out picture-in-picture to float over other apps. Every timer keeps counting in a background tab, and any timer exports as a video. No download, no sign-up.
Its dial 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.
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.
