This timer draws 4 hours as 20 concentric rings; one empties every 12 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 round of golf, a slow-cooker run on high, or a sub-four marathon attempt.
Four hours is a round of golf, a slow cooker on high, and the marathon time that most club runners chase first. Each ring on the dial is twelve minutes, so five rings is an hour and the face reads as four hour-long quarters. At this length you are not watching the dial; you are leaving it somewhere and trusting the chime.
Eighteen holes at a normal pace take about four hours for a group of four, and most courses ask for that or less. A dial started on the first tee shows whether the group is on pace: ring ten should fall around the turn. It is also the honest answer to the question of when you will be home.
Most slow-cooker recipes give two times, roughly four hours on high or eight on low, for the same result. Four hours on high suits a stew, a chilli, or a pulled chicken when the day started late. Start the dial as the lid goes on and leave it; the chime carries across a house, and the 8 hour dial is the low-setting equivalent for a morning start.
Breaking four hours over the marathon distance means holding about nine minutes and nine seconds per mile, or five minutes forty-one per kilometre, for the whole 42.195 kilometres. On this dial the halfway mark, ring ten, should fall as you pass the half-marathon point with a little in hand. Runners cannot carry a screen, but a supporter at a fixed point can hold the dial and call out the rings gone.
Because every fifth ring is an hour, this dial makes a fair day-planner for a block of work with hourly checkpoints: a report drafted by ring five, revised by ring ten, formatted by ring fifteen, sent at the chime. The 1 hour dial restarted four times gives a chime at each hour instead.
Up one step is the 5 hour dial. Every duration the site publishes is on the timers page.
12 minutes. The dial always has 20 rings, and this timer runs 4 hours.
Yes. The nearest pages are the 3 hour timer and the 5 hour 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.
