Click Start to begin the Work interval; the timer switches to Break automatically when it reaches zero, then back to Work when the Break ends.
- Set Work minutes (1-120, default 25) and Break minutes (1-60, default 5), or leave the defaults for the classic 25/5 split.
- Click Start. The phase label reads "Work" and the countdown ticks down.
- Let it flip on its own: "Break" starts when Work hits zero, "Work" starts again when Break hits zero, repeating for as long as the tab stays open.
Pomodoro Timer Online
Run a Pomodoro work/break timer to structure a focus session - not a plain single countdown, since the timer keeps alternating between a Work interval and a Break interval on its own once you start it.
Set the Work length (1-120 minutes, default 25) and the Break length (1-60 minutes, default 5) before you start, so the cycle matches your own routine instead of a fixed 25/5 split. A phase label always shows which interval is active ("Work" or "Break") so you never lose track of where you are.
Click Start to begin the Work interval; the timer switches to Break automatically when it reaches zero, then back to Work when the Break ends, and keeps repeating for as long as you leave it running. Pause holds the countdown in place; Reset returns to the start of the current Work interval using whatever Work/Break minutes are currently set.
Everything runs locally in this browser tab - no upload and no account. Closing or reloading the tab stops the timer; it does not run or notify in the background, and it does not count how many Work/Break cycles you have completed this session.
Want a single one-off countdown instead of a repeating cycle? Use the plain countdown timer. Want the classic 25-minute/5-minute split with no adjustment needed? Leave the defaults as they are and just click Start.
Frequently Asked Questions
What does Pomodoro Timer Online do?
It runs a Pomodoro work/break timer that keeps alternating between a Work interval and a Break interval on its own, instead of stopping after one countdown.
Can I change the 25/5 split?
Yes. Set the Work length (1-120 minutes, default 25) and the Break length (1-60 minutes, default 5) before you start, so the cycle matches your own routine.
What do Pause and Reset do?
Pause holds the countdown in place without changing the phase. Reset returns to the start of the current Work interval using whatever Work/Break minutes are currently set.
Does it keep running if I close the tab or switch away?
No. Everything runs locally in this browser tab with no upload and no account; closing or reloading the tab stops the timer, and it does not run or notify in the background.
