Time is drawn as 20 concentric rings that empty one by one, so how much is left reads from across a room without a single digit. Set any length, take it fullscreen, and the chime marks zero.
A visual timer shows how much is left as an amount, not a number. A digit tells you "6:42" and asks you to work out what that means; a shape tells you "about a third". This page draws time as 20 concentric rings that empty from the outside in, so remaining time is an area you can see from across a room, the way a red wedge on a mechanical visual timer works, but for any length up to 100 hours and on any screen.
On a wall. Open the page on a spare tablet or laptop, fullscreen with the f key, and lean it where it is seen. Ten minutes is preloaded; type any length in the custom fields first if you need another.
Over other windows. The Pop out control floats a small dial in picture-in-picture, so it stays visible over a document, a game, or a video call.
On a stream or a slide. The overlay URL below adds a transparent dial to an OBS scene; a video export drops one into a slideshow.
| Situation | Try | Each ring |
|---|---|---|
| Get shoes on, leave the house | 5 minutes | 15 seconds |
| Screen time before dinner | 30 minutes | 90 seconds |
| Homework, one subject | 25 minutes | 75 seconds |
| Quiet time, waiting room, long drive | 1 hour | 3 minutes |
Name the end before you start: "when the rings are gone, we go." A visual timer works because the end is not negotiable, so avoid adding minutes at zero. For short things, make sure the rings move fast enough to be noticed; under two minutes each ring lasts only seconds and the shrinking is obvious. For long things, check in with the child at half rings, not at random. And keep the chime audible, since the sound is the hard stop that the picture leads up to.
The classroom timer has lesson-shaped routines, and timers for kids and transitions covers the home side in more depth. If you are curious what the rings are doing and why, what a radial timer is explains it.
Anyone who feels time better than they read it: classrooms, focus sessions, homework, transitions between activities. Watching the rings empty makes the remaining time concrete in a way a countdown number is not.
Yes. The fullscreen view is the dial and the time and nothing else, made for a projector or a spare screen at the front of a room.
A clear double chime at zero, and the dial keeps pulsing until you stop it, so the end of time is both seen and heard.
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.
