This timer draws 15 minutes as 20 concentric rings; one empties every 45 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 focused work sprint, simmering rice, or a walk around the block.
Calendars run on the quarter hour, so a fifteen-minute block drops into a real schedule without moving anything else. A task with its own slot tends to actually happen, while a floating one keeps sliding to tomorrow. The timer's job is holding the edges of the slot once it begins.
Fifteen minutes is the unit that calendars, parking, and school bells all agree on. It is long enough to get something done and short enough to promise. On the dial, each ring is forty-five seconds, so four rings is three minutes and the face splits into five three-minute fifths, which is handy for pacing.
Fifteen minutes is the sprint length for people who find twenty-five too long to commit to. Pick one task, start the dial, and work on nothing else until the chime. Three sprints with short breaks between them make an hour of real work; the 5 minute dial covers the breaks. If sprints keep ending mid-thought, move up to the 25 minute pomodoro length.
White rice by the absorption method simmers, covered, for about fifteen minutes after the water comes back to the boil, then rests off the heat for five. Start the dial as the lid goes on and do not lift it before the chime. The five-minute rest can run on a second dial.
Fifteen minutes out the door and back is about a kilometre at an easy pace. Set the dial, walk until ring ten, and turn around. The chime lands at the door. It is the smallest walk that reliably clears a head.
Three fives change at rings seven and thirteen (roughly); five threes change every four rings. For clean five-minute chimes, run the 5 minute dial three times.
Down one step is 14 minutes; up is the 16 minute dial and then the 20 minute nap. The card has a matching fifteen-minute video, and the full range is on the timers page.
45 seconds. The dial always has 20 rings, and this timer runs 15 minutes.
Yes. The nearest pages are the 10 minute timer and the 20 minute timer, and the custom field on any dial takes an exact 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.
