How to use the Pomodoro timer
- Set your work length (the classic Pomodoro is 25 minutes) and your break length (5 minutes works well). The defaults are filled in for you.
- Press Start. The big mm:ss display counts down and the label above it shows whether you are in a Work or Break phase.
- When the work phase hits zero, the timer automatically begins your break, and the completed sessions counter goes up by one.
- When the break ends, it rolls straight back into the next work phase — keep going for as many sessions as you like.
- Press Pause to hold the clock, then Start again to resume from exactly where you stopped. Reset clears the timer and the session count back to the start.
What is the Pomodoro Technique?
The Pomodoro Technique, created by Francesco Cirillo in the late 1980s, breaks work into short, focused intervals separated by deliberate rests. Each focused interval — typically 25 minutes — is one pomodoro, named after the tomato-shaped kitchen timer Cirillo used as a student. The idea is deceptively simple: pick a single task, work on it without distraction until the timer rings, then take a short break before the next round. After several pomodoros you take a longer break. Committing to just one short block at a time makes starting easier, and the regular breaks keep your mind fresh so you can sustain focus across a whole day.
Why time-boxing works
Working against a ticking clock turns a vague, open-ended task into a concrete, finite goal: do this until the timer ends. That small constraint is surprisingly powerful. It discourages multitasking, because you have committed to one thing for one block. It makes procrastination harder, because twenty-five minutes feels manageable even when the whole project does not. And it builds a natural rhythm of effort and recovery, so you are far less likely to burn out than if you tried to grind for hours straight. The completed-sessions counter also gives you a satisfying, visible record of the focus you have put in.
Tips for better focus sessions
- Pick one task per pomodoro: decide exactly what you will work on before you press Start.
- Protect the block: silence notifications and resist the urge to check messages until the break.
- Use the break properly: stand up, stretch, look away from the screen — rest your attention, do not just switch screens.
- Adjust the lengths to suit you: some people focus better in 50-minute blocks with 10-minute breaks. The work and break fields let you set whatever rhythm fits the task.
- Take a longer break every few sessions: after four pomodoros, step away for fifteen to thirty minutes to fully recharge.
Is it private?
Completely. The timer runs in JavaScript right inside this page using your device's own clock. The lengths you set and the sessions you complete never leave your browser — there is no server call, no account and no tracking. Close the tab and nothing is stored or sent anywhere. Because the countdown is measured against a real end-time rather than by counting ticks, it stays accurate even if the tab is briefly inactive.
Frequently asked questions
Can I change the work and break lengths?
Yes. Type any number of minutes into the work and break fields — from a quick 5-minute sprint to a long 90-minute deep-work block. The lengths lock while the clock is running, and you can change them again whenever the timer is paused or reset.
What counts as a completed session?
Each time a full work phase counts all the way down to zero, the completed-sessions counter goes up by one. Breaks are not counted — only finished focus blocks — so the number is a clean tally of how much real work you have put in.
Will it make a sound when a phase ends?
This is a silent, visual timer by design — it will not surprise you with sound in a quiet room or shared space. When a phase ends, the phase label switches between Work and Break and the countdown restarts for the new phase so you can see the change at a glance.
Does closing the tab keep the timer running?
No. Everything lives in the page, so closing or reloading the tab resets the timer and the session count. While the tab stays open you can pause and resume freely without losing your place.
