This timer draws 13 minutes as 20 concentric rings; one empties every 39 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 baked salmon fillet, poaching chicken breasts, or a morning news podcast.
Almost nobody plans a thirteen-minute task. You arrive at thirteen because a recipe says twelve to fifteen and you pick the middle, or because a podcast episode happens to run that long. It is a rounding number, and the dial treats it like any other: twenty rings, one every thirty-nine seconds, a slow sweep that is easy to check on the way past the oven.
A salmon fillet an inch thick bakes in about twelve to fifteen minutes in a hot oven, and thirteen is where most home ovens land for a fillet that flakes but stays moist in the centre. Start the dial as the tray goes in. At the chime, press the thickest part with a fork: if it flakes, it is done, and if it resists, give it two more minutes on a fresh dial.
Boneless chicken breasts poached gently in barely simmering water take twelve to fifteen minutes depending on size, and thirteen suits an average one. Bring the water up, drop it to a bare tremble, and start the dial as the chicken goes in. Check the centre at the chime; it should be opaque all the way through with no pink.
Many daily news podcasts run around a quarter of an hour, and thirteen minutes is a common length for the short ones. If you time a walk to one, this dial tells you when to turn back at the halfway point: ring ten is six and a half minutes out.
Thirteen does not divide neatly, which is a reason to keep it whole. If you need halves, the midpoint is ring ten. If you need thirds, they fall at roughly rings seven and thirteen. For anything that wants clean pieces, the 12 minute dial divides four ways and the 15 minute dial divides three.
If the recipe says twelve, set twelve. If it says fourteen, the 14 minute dial is right there. Thirteen is for when you have picked the middle on purpose. The card includes a thirteen-minute video, and every duration lives on the timers page.

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.
