Twenty-five minutes is one Pomodoro. Pick one task, press Start and work on nothing else until it beeps. Then take a five-minute break.
What people use a 25 minute timer for
- One Pomodoro of focused work or study.
- A timed writing session, with no editing until the beep.
- A long enough slot to get into a hard problem without watching the clock.
How this timer works
- It remembers the moment it will end, so it stays right when you switch tabs or your phone locks.
- At zero it plays a few short beeps, vibrates on phones that can, and shows "Time's up" in the tab title.
- While it runs it asks the screen to stay on. Full screen makes the numbers big enough to read across a room.

Questions people ask
What is the Pomodoro technique?
A way of working in 25-minute blocks, each followed by a 5-minute break, with a longer break of 15 to 30 minutes after four blocks. It was worked out by Francesco Cirillo in the late 1980s and named after his tomato-shaped kitchen timer.
What do I do when the timer goes off?
Stop, even mid-sentence, and take five minutes away from the screen. The 5 minute timer on this site is there for the break.
Does the timer work without an internet connection?
Once the page has loaded, yes. The timer runs in your browser and does not need the network to count down or to beep.
Counting down to a date rather than a few minutes? The countdown maker works for any day, and with Pro the Countdown app puts it on your iPhone Lock Screen.
