Pomodoro Timer
A focus timer that runs the full cycle for you: work, short break, work, and a longer break every fourth round — with a chime at each changeover and a running count of what you have finished today.
How to use the Pomodoro Timer
- Adjust the focus, short break and long break lengths if the defaults do not suit your work, and set how many focus rounds come before a long break.
- Press start. The bar fills as the session runs and a chime plays when it ends, then the next phase begins automatically.
- Use skip to jump ahead, pause to stop the clock, and reset to go back to the first focus session. Keep the tab open while the timer runs.
About the Pomodoro Timer
The Pomodoro technique works less because twenty-five minutes is a magic number and more because a countdown makes starting cheap. Committing to one short block is easy in a way that committing to an afternoon is not, and the enforced break stops the quiet slide from concentration into fatigue. All four durations here are adjustable, which matters: twenty-five minutes suits reading and admin, while deep work like writing or debugging often runs better at forty-five or fifty with a longer rest. The one rule worth keeping is that the break is a real break — standing up and looking at something further than an arm away does more for the next session than scrolling does. Your session count is stored on this device for the current day and nothing is sent anywhere.
Frequently asked questions
How long is a Pomodoro session?
Traditionally 25 minutes of focus followed by a 5 minute break, with a 15 to 30 minute break after four rounds. All of those lengths are editable here.
Does the timer keep running if I switch tabs?
Yes, as long as the tab stays open. Some browsers throttle background tabs, so the chime may arrive a moment late if the tab has been hidden for a long time.
Will it still work offline?
Yes. Once the page has loaded, the timer runs entirely in your browser and needs no connection.
What should I do during the break?
Leave the screen if you can — stand up, stretch, get water, look out of a window. The break exists to reset your attention, and scrolling a feed does not do that.
How long should a study session be?
The classic tomato technique is 25 minutes of focus and a 5 minute break, with a longer break after four rounds. For heavier study some people prefer 50 minutes and a 10 minute break; both are configurable here.
