Pomodoro Timer
Start a 25-minute focus session; breaks and long breaks follow automatically.
What this tool does
The Pomodoro Technique works in short bursts: 25 minutes of focused work, then a 5-minute break, and after four rounds a longer break of 15 to 30 minutes. Press Start and the timer runs the cycle for you, with the time in the browser tab title and a sound when each session ends. All the lengths can be changed.
Counts down each focus session and break in turn.
Counts finished sessions and focus time, and lets you copy or download the log.
How to use it
- Set the focus, short break and long break lengths if you do not want the defaults.
- Press Start.
- Work until the chime, then take the break.
- Copy or download the session log at the end of the day.
Why use this timer
Runs the classic cycle of focus sessions, short breaks and a long break after four rounds, with the countdown in the tab title so you can see it from another tab. Dividing work into short, timed bursts makes a large task less daunting and builds in regular breaks. A timer that runs the whole cycle means you do not have to remember what comes next.
Why we built it
We built the Pomodoro timer to run the whole focus-and-break cycle for you, with the countdown in the tab title. Use the countdown timer for single timers and the online alarm clock for a set time.

Who this tool is for
- Students revising
- Writers and developers working in focused sprints
- Anyone who forgets to take breaks
When to use it
- Studying or revising.
- Writing, coding or admin that you keep putting off.
- Working in short sprints with a team.
- Making yourself take breaks.
How it works
The timer stores an end time and recalculates the remaining seconds from the clock, so it stays accurate even when the browser slows a background tab. After each focus session the next break is short, and after every fourth session it is long. Auto-start can begin the next session when the previous one ends.
Francesco Cirillo named the method after a tomato-shaped kitchen timer (pomodoro is Italian for tomato). The 25-minute length is traditional rather than magic; use what works for you.
