This timer draws 16 minutes as 20 concentric rings; one empties every 48 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 frozen pizza in the oven, walking a brisk mile, or a sheet mask.
Sixteen minutes is four Tabata blocks laid end to end, a frozen pizza, and a brisk mile on foot. It is also two eights, which is a convenient way to think of it. Each ring on the dial is forty-eight seconds, so five rings is four minutes and the face splits into four equal four-minute quarters.
A single Tabata block is four minutes: eight rounds of twenty seconds on and ten off. Four blocks in a row, with no rest between, is sixteen minutes exactly, and each block ends at a quarter of the face. The Tabata page runs one block with a chime at every change; for four blocks with a breather between them, restart that page, and use this dial only when you want the whole session as one sweep.
Most frozen pizzas list twelve to sixteen minutes in a hot oven, and sixteen suits a thick base or a cooler oven. Start the dial as the pizza goes on the rack and look for browned cheese and a crisp edge at the chime. Thin-crust pizzas are usually done earlier, so use the 12 minute dial and check.
Walking a mile in sixteen minutes is a brisk pace, just under four miles an hour, which is the speed most guidance calls moderate exercise. Start the dial at the start of a measured mile and see whether you beat the chime. If you do, that pace is yours; if not, sixteen is the target for next time.
Packet instructions for sheet masks usually say fifteen to twenty minutes, and sixteen is as good a middle as any. Set the dial, lie down, and peel it off at the chime rather than letting it dry out on your face.
Two hard-boiled eggs dropped in eight minutes apart, or two run-throughs of an eight-minute core routine, fit sixteen minutes with the switch at ring ten. For a chime at the switch, run the 8 minute dial twice.
Fifteen is the calendar's quarter hour; eighteen is a talk. Both are one step away: the 15 minute and 18 minute dials. A sixteen-minute video sits on the card, and the timers page has the rest.

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.
