This timer draws 2 hours as 20 concentric rings; one empties every 6 minutes, 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 long study session, a low oven braise, or time-boxing a weekend project.
Two hours is one full pomodoro set, a low oven braise, a long study session, and the size of box most weekend projects fit in. On the dial, each ring is six minutes; every fifth ring is half an hour, so the face reads as four quarters of thirty minutes. It moves slowly enough that you stop checking it, which at this length is the point.
Twenty-five minutes on and five off, four times, is a hundred and twenty minutes, so the classic pomodoro set fits two hours to the minute. Each block ends a little after ring four, nine, fourteen, and nineteen. The pomodoro page runs the set with the breaks starting on their own and a chime at every change; this single dial suits people who want the whole morning as one shape and a single chime at the end.
Beef shin, lamb shoulder, or a pot of short ribs in a low oven take two to three hours to fall apart, and two hours is the first check. Start the dial as the pot goes in with the lid on. At the chime, the meat should give to a fork; if it still resists, another half hour on the 30 minute dial, and again if needed.
Two hours is about the longest study sitting that stays productive without a real break. Start the dial with the books open, stand up at ring ten for a few minutes, and stop at the chime. For a session that mirrors an exam, the 3 hour dial is the length most final sittings use.
A weekend project that has no box spreads over the whole weekend. Give it two hours on the dial and one clear goal: the shelf up, the draft finished, the garage half cleared. The rule is to stop at the chime and decide then whether it deserves another two, which is a different question from whether to keep going.
Down one step is the 90 minute dial. The card has a two-hour video, and the whole range is listed on the timers page.
6 minutes. The dial always has 20 rings, and this timer runs 2 hours.

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.
