Pomodoro Timer

A free pomodoro timer for the browser. Twenty-five minutes of focus, five minutes of break, repeated four times — then a longer break. Run it in a tab, ignore the phone.

Pomodoro

25 minutes focus, 5 minutes break — repeated.

Focus
25:00
Cycle 1 of 4

Eyes on the task. Phone away.

The pomodoro technique is the time-management cheat code that survived four decades. Set a 25-minute timer, work on one thing until it rings, take a 5-minute break, repeat. Every fourth cycle, take a longer 15-minute break. The structure removes decision fatigue: you don't ask whether to keep going, you just check the timer. This page handles the cycle math automatically. Press start, work the focus block, the timer rings on its own, the page auto-flips to the break, and the cycle counter increments. There is no setup, no account, and nothing to install. The chime is generated with Web Audio API — three short tones at 660 Hz, distinct enough to register without being annoying. Use pomodoro for studying, deep work, writing, debugging, drawing, learning a language, getting through a tedious dataset cleanup. The constraint is the productive part: 25 minutes is short enough that you can't procrastinate seriously, long enough to enter flow on a small task. After four cycles you've banked roughly two hours of focused work — more than most people manage in a full unstructured workday.

FAQ

Does the timer keep running if I switch tabs?
Yes — the timer is JavaScript-driven and continues counting in the background. The chime fires when the tab is in focus.
Why 25 minutes specifically?
Francesco Cirillo's original kitchen tomato (pomodoro in Italian) clocked 25 minutes. It's empirically the sweet spot between attention span and work block size.
Can I change the duration?
This page is fixed at 25/5/15. For arbitrary durations use the timer family pages instead.
What's a long break?
After every 4 work cycles take 15 minutes off — coffee, walk, snack — to reset attention before the next round.
