Four 25 minute focus blocks with 5 minute breaks between, advancing on their own. Each block is drawn as 20 rings that empty one by one, so a glance gives you its shape without breaking focus.
The Pomodoro Technique comes from Francesco Cirillo, who worked it out as a student in the late 1980s with a tomato-shaped kitchen timer. The shape has not changed: a fixed block of work, a short rest, repeat, with a longer rest after a set of four. It suits people who stall at the start of a task, people whose work arrives as a pile of small jobs, and anyone who loses track of the afternoon. It suits writing, revision, admin, and coding less well once you are deep in a hard problem, which is where the 50/10 version takes over.
This page arrives with the cycle already built: four focus blocks of 25 minutes, three 5 minute breaks between them, and a chime at every change. Press start and leave it. Each focus block is its own dial of 20 rings, so a ring falls every 75 seconds and the ring count doubles as a rough clock: twelve rings left means fifteen minutes to go. The whole set runs 115 minutes, and the cycle ends on the fourth focus block rather than an empty break. If four rounds is too many, open Cycles and step the pomodoro cycle's loop count down to two or three.
Skipping the break because the work is going well is the most common one, and it is exactly what the rest is for: the next block starts fresher because you stepped out. Answering a message during the focus block resets more than the minute it takes. Letting the break run long is the other failure; the chime that opens the next block is the fix, so leave the volume up. Finally, a block that ends mid-thought is not a problem. Write the next sentence down, take the rest, and pick it up.
If you routinely hit your stride at minute twenty and resent the chime, move to 50/10 or run a single 45 minute timer with a break of your own. If 25 feels long, especially when a task is dreaded, a plain 15 minute timer gets you started and the second one is easier. The guide on starting with the Pomodoro Technique covers the first week in more detail.
The classic pomodoro rhythm: long enough to get somewhere, short enough to start without dread. If you prefer deeper blocks, the 50/10 pomodoro timer runs the same way.
Yes. Each block chimes and the next begins on its own; pause any time and the cycle waits with you.
The cycle ends with a chime. Start another round, or take a longer break first.
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.
