How to use Pomodoro Timer
- Set your durations. Pick focus, short-break and long-break lengths, plus how many focus sessions run before a long break. The defaults are the classic 25 / 5 / 15.
- Add your tasks. Type tasks into the list and tick them off as you finish. Everything is saved on your device automatically.
- Start a session. Press start and get to work. The remaining time shows in the browser tab title, so you can glance at it from any tab.
- Rest when it beeps. A short beep marks the end of each session, and the timer moves you into the right break automatically.

Pomodoro Timer Frequently asked questions
- It is a time-management method: work in focused 25-minute sessions (Pomodoros), take a 5-minute break, and after four sessions take a longer 15 to 30 minute break. The structure fights fatigue and makes big tasks feel manageable.

- Yes. The timer is anchored to the clock time it should finish, not to a per-second counter, so it stays accurate even when the tab is in the background or your laptop sleeps briefly.
- In your browser's local storage, on your device only. They are never uploaded anywhere, so they persist between visits on the same browser but cannot follow you to another device.
- Yes. If the timer is not running, the current session resets to the new length immediately. If it is running, the new lengths apply from the next session.
