52/17 Pomodoro Timer

52 minutes of focus, a 17-minute break, and a 17-minute long break every four rounds. Adjust anything in the settings panel; the preset is only a starting point.

When this split works

A steady rhythm for people who dislike watching the clock.

The 52/17 rhythm comes from workplace observation rather than a tradition, and the odd numbers are part of its charm. Fifty-two minutes of work followed by seventeen minutes away from the screen breaks the habit of checking the clock at round numbers, which makes the timer feel less mechanical. The break is long enough to leave your desk and short enough that the day does not fragment.

This timer uses seventeen minutes for the long break as well, so the whole session keeps the same proportions whether you are on your first round or your fifth.

How to use this timer

Press start and leave the tab open. The timer uses absolute end times, so it stays correct after sleep, tab switching or a throttled background tab.

  1. Choose a preset or set your own focus, short-break and long-break lengths in the settings panel.
  2. Start the focus block and work on one task. Press Space to pause, S to skip and R to reset.
  3. Take the break the timer offers. Enable auto-start if you want the next block to begin on its own.

Pomodoro questions

Is this Pomodoro timer free?

Yes. The timer, presets and settings are free and need no account. Your data stays in this browser and nothing is stored on our servers.

Does the timer keep running when I switch tabs or the screen sleeps?

Yes. The engine stores an absolute end time and recomputes the remaining seconds from the device clock, so a throttled or sleeping tab resumes at the right value. Keep the tab open if you want the sound cue.

What do the preset numbers mean?

The first number is the focus length in minutes and the second is the short break. A long break follows the number of rounds shown in the timer, and the presets use 15, 30 or 17 minutes for it.

Can I use it on my phone?

Yes, the layout is responsive and the timer can run fullscreen. Desktop notifications need permission, and the mini player uses the Document Picture-in-Picture API where the browser supports it.
