This timer draws 90 seconds as 20 concentric rings; one empties every 4.5 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 microwave rice pouch, rest between heavy lifting sets, or a debate rebuttal.
A minute and a half is the length that turns up on packaging. Microwave rice pouches, steamed vegetable bags, and reheat instructions on ready meals all seem to settle on ninety seconds, and it is also a common rest between heavy sets. The dial drops a ring every four and a half seconds, so it moves noticeably while you watch and still reads clearly from across a kitchen.
Thirty seconds is a conditioning rest; ninety seconds is a strength rest. It is roughly the gap where you can add weight to the bar, chalk up, and be ready for a set of five without either rushing or cooling down. Start the dial as you rack the bar and lift again at the chime. If you are working near a max, stretch the rest to two minutes or more.
Rice pouches and grain mixes cook in ninety seconds from a pierced packet, and the timing matters more than it looks: shorter leaves the centre cold, longer dries the edges. Start the dial as you press start on the microwave, since the microwave's own beep is often quieter than this chime.
Ninety seconds is a common rebuttal length in school and university debating, and the same span turns up in interview formats where each candidate gets a short answer. Rehearsing to it is the only way to learn how much you can say. The rings run silently, so you can practise out loud without a clock ticking under you.
Ninety is three thirties or two forty-fives. A stretch with three positions changes at every seventh ring; a two-sided hold switches at ring ten. If you find yourself always splitting it, the 30 second dial or the 45 second dial restarted may be simpler.
Shorter is the 60 second dial; longer is two minutes. The rest of the range lives on the timers page.
4.5 seconds. The dial always has 20 rings, and this timer runs 90 seconds.
Yes. The nearest pages are the 1 minute 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 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.
