This timer draws 1 hour as 20 concentric rings; one empties every 3 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 an hour of focused work, a slow-cooker check-in, or a parking meter.
The first stretch of any deep task goes to loading the problem back into your head, and research on office interruptions puts the time to fully return to a task at over twenty minutes. An unbroken hour pays that warm-up once and leaves the rest for the actual work. Sixty minutes in scattered pieces pays it at every restart.
An hour is the unit everyone plans in, and the first length where the dial's slowness becomes a feature. Each ring lasts three minutes, so the face changes about as often as you would look up anyway; you see a block of time with a shape rather than a clock that nags. Ring ten is the half hour, and every fifth ring is a quarter.
The simplest deep-work practice is one hour, one task, and a visible end. Start the dial, put the phone in another room, and work until the chime. If an hour is too long to commit to at first, the 50 minute dial is the lecture-length version and the 45 minute dial is the class period. If it is too short, the 90 minute dial is the next natural step.
Twenty-five on, five off, twice, is sixty minutes exactly. On this dial the first block ends a little after ring eight, the first break at ring ten, and the second block a little after ring eighteen. The pomodoro page runs the cycle with the breaks starting on their own; use this dial when you want the hour as one face.
Most slow-cooker recipes want the lid left alone, but a check at the hour is reasonable for anything you have not cooked before: a stir, a taste, a look at the liquid level. Set the dial when you leave the kitchen and the chime carries through the house. For the full run, the 4 hour dial covers a high setting and the 8 hour dial covers low.
An hour of parking is a common ticket, and the fine for forgetting it costs far more than the hour. Start the dial as you walk away from the car, and set it for a few minutes less than the ticket if the walk back is long.
The card has a one-hour video for playing the count on a shared screen, and every duration lives on the timers page.
3 minutes. The dial always has 20 rings, and this timer runs 1 hour.
Yes. The nearest pages are the 45 minute timer and the 2 hour 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.
