The short answer
Pick one task, start a 25 minute timer and work only on that task until it rings. Take 5 minutes off, away from the work. Repeat. After the fourth pomodoro, take a long break of 15 to 30 minutes, then start a new cycle.
The timer below runs this cycle for you: 25 minutes of Focus, a 5 minute Short break and a 15 minute Long break every 4 rounds. The dots under the clock show where you are in the current cycle and the counter shows how many pomodoros you finished today.

Francesco Cirillo developed the method as a university student in the late 1980s, using a kitchen timer shaped like a tomato (pomodoro in Italian). He later described it in a book and a training program, and the core rules have stayed the same: one task, a fixed interval, a real break, and a record of what you finished.
It helps for three reasons. First, 25 minutes is short enough that starting a dreaded task feels manageable, which is the main cure for procrastination. Second, the ringing timer takes over the job of deciding when to stop, so you do not have to monitor your own attention. Third, counting pomodoros gives you an honest measure of effort: after a week you know that writing a report takes six pomodoros, not one afternoon.
The rules of a pomodoro
- One pomodoro, one task. If the task is bigger than five or six pomodoros, split it; if it is tiny, group several small tasks into one pomodoro.
- A pomodoro is not divided. If you abandon it halfway to answer a message, it does not count; start a new one.
- Handle interruptions with a note. When something pops into your head or someone asks for something, write it on a list and return to the task. Deal with it in a break or a later pomodoro.
- If you finish early, use the remaining minutes to review or improve what you did instead of starting something new.
- The break is mandatory. Skipping breaks to keep going feels productive for a while and then costs you the afternoon.
Adapting the lengths
25/5 is a starting point, not a law. Writers and programmers often find that 25 minutes ends just as they reach full concentration, while students revising flashcards or people with many small tasks do well with the classic rhythm. Try a setting for a few days before judging it. In the timer's settings you can change Focus from 1 to 180 minutes, the Short break up to 60, the Long break up to 120 and how often the long break comes (Long break every 1 to 12 rounds). Your values are remembered on this device.
| Pattern | Focus | Short break | Long break | Good for |
|---|---|---|---|---|
| Classic | 25 min | 5 min | 15 to 30 min after 4 rounds | Starting habits, studying, mixed small tasks |
| Longer focus | 50 min | 10 min | 30 min after 3 rounds | Writing, coding, design work |
| Deep work | 90 min | 20 min | None or after 2 rounds | Single demanding projects with no meetings |
| Short sprints | 15 min | 3 min | 15 min after 4 rounds | Low energy days, tasks you keep avoiding |
What to do in the breaks
A break only restores attention if you actually switch off. Good short breaks take your eyes and body away from the screen; bad ones start something that is hard to stop.
- Stand up, stretch, walk to the window or around the room.
- Drink water or make tea. Look at something far away to rest your eyes.
- Do a small physical chore: empty the dishwasher, water a plant.
- Avoid messages, social media and news: five minutes of scrolling rarely ends after five minutes, and it fills your head with new problems.
- Use long breaks for food, a short walk outside or a conversation.
Combining Pomodoro with a to-do list
The technique is strongest when paired with a simple list. In the morning, write the tasks you want to finish today and estimate each in pomodoros. Put a mark next to a task each time you complete a pomodoro on it, and note interruptions in the margin. At the end of the day compare estimates with reality; within a couple of weeks your estimates get noticeably better.
Planning in pomodoros also sets a realistic limit. Few people manage more than 8 to 12 focused pomodoros in a day once meetings and email are counted. If your list needs 20, you know in the morning that something has to move.
Common mistakes
- Working through the break when the timer rings. Stop at a natural point within a minute or two, but take the break.
- Checking email or chat at the start of every pomodoro. Batch them into a dedicated pomodoro or into long breaks.
- Picking vague tasks such as work on the project. Write the next concrete action instead: draft the introduction.
- Using Pomodoro for meetings or calls. It is designed for work you control; schedule pomodoros around meetings.
- Giving up after one bad day. Adjust the lengths, keep the breaks, and track a full week before deciding.
