This timer draws 45 seconds as 20 concentric rings; one empties every 2.3 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 HIIT work interval, an elevator pitch run-through, or blanching spinach.
Three quarters of a minute is an in-between length, and that is the point of it. It is longer than the half minute that most rests default to and shorter than the full minute that starts to feel like a break. The dial drops a ring every two and a quarter seconds, a slow enough rhythm to glance at mid-exercise and still know how much is left.
Forty-five seconds of work and fifteen of rest is one of the most common circuit splits, because forty-five is long enough to get a real set done at a controlled pace. Squats, push-ups, kettlebell swings, and rowing all fit. The interval timer page runs eight rounds of exactly that with a chime at each change, so use it when you are running the whole circuit. This plain dial is for a single forty-five second effort, or for a rest of that length between heavier sets.
Speakers rehearsing an opening tend to time it once and stop. Run it three times against the dial instead: the first pass finds the places you stumble, the second cuts them, and the third proves the timing holds. Forty-five seconds is enough for a name, a problem, and a single reason to keep listening.
Spinach, kale ribbons, and pea shoots go from raw to bright green and tender in about forty-five seconds in boiling water. Longer and they turn dull; shorter and the stems stay tough. Have the ice water ready before you start the dial, because the chime is the moment to lift them out.
Forty-five seconds is three fifteens, which is handy for a stretch that has three positions, or for holds where you switch sides at each third. If that is how you work, the 15 second dial restarted three times may suit you better. For the neighbours, see the 30 second and 60 second dials, or the full list on the timers page.
2.3 seconds. The dial always has 20 rings, and this timer runs 45 seconds.
Yes. The nearest pages are the 30 second timer and the 60 second 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.
