The Pomodoro Technique, step by step
The Pomodoro Technique splits work into focused blocks of 25 minutes separated by short breaks. Francesco Cirillo developed it as a university student in the late 1980s and named it after the tomato-shaped kitchen timer he used. The idea is simple: a fixed, short block is easier to start than an open-ended task, and regular breaks keep attention fresh.
This timer runs the classic cycle for you: 25 minutes of focus, a 5-minute short break, and a 15-minute long break after every fourth focus session. It can send a browser notification when a block ends.
How to use it
- Pick one task and press Start for a 25-minute focus block.
- Work only on that task until the timer ends. Note distractions on paper instead of acting on them.
- Take the break the timer switches to: 5 minutes, or 15 minutes after every fourth session.
- Press Enable notifications once if you want an alert while working in another tab.
Example: one full set of four
Start with focus, let each block finish 8 times
short:1 → work:1 → short:2 → work:2 → short:3 → work:3 → long:4 → work:4
The number counts completed focus sessions. The fourth completed session earns the long break, then a new set begins.
Why it works
Starting is often the hardest part of a big task. Committing to just 25 minutes lowers that barrier, and the visible countdown creates a gentle sense of urgency. The breaks matter as much as the work: stepping away regularly prevents the slow slide into distraction that comes with long unbroken stretches, and many people find they get more done in four focused sessions than in a vague afternoon.
Counting sessions also improves planning. After a few days you know that writing a report takes about six pomodoros, which makes estimates far more honest.
Adapting the rhythm
25 and 5 minutes are a starting point, not a law. Work that needs deep concentration, such as programming or writing, often suits longer blocks of 45 to 50 minutes with 10-minute breaks. If you are often interrupted, shorter blocks keep the method usable. Keep the rule that a block, once started, is protected.
Use breaks as breaks
Checking email or social media during a break keeps your mind on screens. Stand up, look out of a window, drink water or stretch. Those few minutes away are what make the next block sharp.
Questions
Does the timer keep running in another tab?
Yes, as long as the page stays open. With notifications enabled, you get an alert when a block ends even if the tab is in the background.
What if I get interrupted?
Cirillo's rule is that an interrupted pomodoro does not count. Pause or reset, deal with the interruption, and start a fresh block.
Is any data stored?
No. The timer runs in your browser tab, and notifications are only requested after you switch them on.
