Fifty minutes of work, a ten minute break, four rounds. The longer block suits writing, code, and problem sets, where 25 minutes ends just as you get moving; the rings drain one every two and a half minutes, so depth stays visible at a glance.
Fifty minutes on, ten off is the pomodoro for work that needs a run-up: a chapter, a feature, a proof, a lesson plan. The classic 25 minute block ends about when a hard problem has finished loading into your head; the longer block keeps you there for another half hour. The trade is that the rest has to be real, because fifty minutes of concentration spends more than twenty-five, and the ten minute break is what buys the next one. This page runs four rounds: 50, 10, 50, 10, 50, 10, 50, which is 230 minutes end to end, closing on the last focus block.
| Block | Time | Job |
|---|---|---|
| Focus 1 | 8:30 to 9:20 | The hardest thing on the list, while the head is clearest |
| Break | 9:20 to 9:30 | Walk to the window, water, nothing with a screen |
| Focus 2 | 9:30 to 10:20 | Continue the same task; do not switch |
| Break | 10:20 to 10:30 | Snack, quick reply to anything urgent |
| Focus 3 | 10:30 to 11:20 | Second task, or the first one's cleanup |
| Break | 11:20 to 11:30 | Stretch; plan the last block on paper |
| Focus 4 | 11:30 to 12:20 | Lighter work: review, replies, tomorrow's list |
The dial does the same on any schedule: 20 rings per block, one leaving every two and a half minutes, so a half-empty dial is 25 minutes gone.
Ten minutes is long enough to leave the room, which is the point. Make tea (the 3 minute timer covers the steep), step outside, do the dishes from lunch, lie on the floor. It is not long enough to start a show, open a game, or read a thread to the end, and those are the breaks that swallow the next block. If you want a break that closes on its own, the chime that begins focus does that for you.
Running 50/10 on shallow work is the usual misuse: email in fifty minute blocks is just fifty minutes of email. Save the long block for one thing that needs it. Another failure is stacking two sets back to back; after four rounds, take a rest of at least half an hour, and the 30 minute timer will hold the edge of it. And if the first block feels endless, that is a sign you wanted the 25+5 version today.
Open Cycles and change the numbers: 45/15 gives a longer rest for physical work, 60/10 fits a lecture-shaped hour, 90/20 is the outer edge before the break stops being a break. Reading on focus sprints and deep work covers how to pick between them.
Same rhythm, doubled. Fewer switches suit long-form work; if starting is the hard part, the 25+5 pomodoro timer is the gentler ramp.
Yes. The block chimes, the break begins, and the next block follows it. Pausing holds the whole cycle.
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.
