Pomodoro Timer

How to use it

1. Set the three session lengths in minutes: focus, short break and long break. The defaults are the classic 25 / 5 / 15.
2. Press Start. The ring fills as the block runs, and the label under the clock shows the active phase.
3. The same button pauses and resumes. Reset returns to the first focus block and sets the round counter back to zero.
4. A short beep marks every phase change. After four focus blocks the timer moves into the long break on its own.
5. Keep the tab in the foreground if you rely on the beep: browsers throttle timers in background tabs.

Common use cases

• Study or writing blocks: 25 focused minutes with a guaranteed break, so a long task feels finite.
• Meeting-heavy days: a fixed cycle that forces real pauses instead of back-to-back calls.
• Team sessions: run the same cycle on a shared screen so everyone breaks together.
• Habit building: the round counter shows how many focus blocks you have finished.

Why it stays private

The whole cycle runs in your browser: no network requests and nothing is stored, so the timer works offline and no detail of your session leaves the device. One honest caveat: browsers throttle timers in background tabs, so a beep can arrive late. Keep the tab visible for phase-accurate alerts.

FAQ

Q: How is this different from the countdown timer on this site? A: The countdown timer runs a single countdown to zero. This tool runs a work method: it chains focus blocks and breaks together, counts rounds and starts the long break automatically after every fourth focus block.

Q: What happens when a phase ends? A: A short beep plays, the phase label switches and the next phase starts on its own. Nothing is stored, so closing the tab ends the cycle.

Q: Can I change the session lengths? A: Yes. Focus, short break and long break are all editable in minutes, and a change applies the next time that phase starts.
