The toothbrush timer
One minute of brushing, drawn as 20 rings that give one up every 3 seconds. Prop the phone against the mirror, start it as the brush goes in, and the dial does the counting; nobody has to watch a clock with a mouth full of foam.

Isn't brushing supposed to take two minutes?
For the full dentist-recommended clean, yes, and the 2 minute timer below runs exactly that. One minute is the starter target: for young kids, a midday brush at work, or anyone building the habit up from thirty rushed seconds.
How do I cover the whole mouth in a minute?
Let the rings split it: five rings a quadrant. Upper right, upper left, lower left, lower right, moving on as each five empty, and the chime lands as you finish the last corner.
Does it help kids brush?
That is where the one minute brush usually starts. The rings give the minute a shape a small kid can watch emptying, and the chime decides when brushing ends, so the parent does not have to.

What is a radial timer?
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. With a free account, any timer exports as a video.
Does it keep running in a background tab?
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.
Can I export a timer as a video?
Yes. Sign in with a free account and any timer exports as a 16:9 MP4 of the whole countdown.
Can I put a timer on my stream?
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.
How many timers can I run at once?
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.
