This timer draws 18 minutes as 20 concentric rings; one empties every 54 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 TED-length talk, baking a batch of muffins, or one side of a vinyl record.
Eighteen minutes is the length TED gives its speakers, the bake on a tray of muffins, and roughly one side of a vinyl LP. It splits three ways and six ways cleanly. The dial drops a ring every fifty-four seconds, close enough to a minute that the rings almost count minutes; ring ten is nine minutes, the midpoint.
TED capped its talks at eighteen minutes and the length became a standard for conference keynotes and long-form presentations. If you are preparing one, the dial is for rehearsal: start it with your first line and aim to finish before the chime with a little slack, because a live audience laughs, claps, and slows you down. Run it fullscreen on a second screen while you present and the rings work as a speaker clock nobody else can hear. The speech page is the five-minute version of the same idea.
A standard twelve-hole tray of muffins bakes in eighteen to twenty minutes at a moderately hot oven. Start the dial as the tray goes in and test the middle muffin with a skewer at the chime; if it comes out wet, give them two more minutes. Mini muffins are done sooner, so start checking around ring fourteen.
A side of a twelve-inch LP runs about eighteen to twenty-two minutes, which is why people who listen on vinyl have always had a natural work block: one side, then get up. Set the dial as the needle drops and the chime tells you the side is about to end even if you are in another room and cannot hear the run-out groove.
Down is the 16 minute dial; up is the 20 minute nap, where each ring is exactly a minute. The card includes an eighteen-minute video for playing the count on a shared screen, and every length is on the timers page.
54 seconds. The dial always has 20 rings, and this timer runs 18 minutes.
Yes. The nearest pages are the 16 minute timer and the 20 minute 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 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.
