This timer draws 30 seconds as 20 concentric rings; one empties every 1.5 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 plank hold, rest between exercise sets, or a thorough hand wash.
Thirty seconds of rest between sets keeps conditioning work moving: enough to catch your breath, not enough for your heart rate to settle. Held efforts run on the same half minute, and a plank counted in your head tends to finish early next to one timed against real seconds.
Thirty seconds is where a wait becomes a task. It is long enough to do something in and short enough that you will not wander off. The dial sheds a ring every second and a half, so the whole face is in steady motion the entire time, and the last five rings go quickly enough to bring you back from wherever your attention went.
The simplest plank programme is a ladder of half minutes. Hold for thirty seconds, rest for thirty, and repeat until form breaks. When six rounds feel easy, move the hold to the 45 second dial and keep the rest at thirty. Rather than restarting this card for each step, open two dials side by side, one for the hold and one for the rest, and start each in turn.
If you have to describe yourself, your product, or your research in the time it takes to ride a lift, thirty seconds is the usual budget. Start the dial as you begin talking, and see whether the closing line arrives before the chime or after it. The rings are silent, so a run-through never gets interrupted, and the card shows a matching video if you would rather see the count as a clip.
Thirty on, ten off is the split on the HIIT page, which runs eight rounds of it with a chime at every change; use that page when the half minute is one piece of a circuit. When thirty is not enough for a rest, a full minute is the next standard step. The rest of the range is listed on the timers page.
1.5 seconds. The dial always has 20 rings, and this timer runs 30 seconds.

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.
