The Pomodoro Technique® is a time-management method created by Francesco Cirillo in the late 1980s: you work on one task for a fixed session, traditionally 25 minutes, take a 5-minute break, and take a longer 15–30 minute break after every four sessions. This guide covers the steps, the timing, how to adapt them and what a browser timer can and cannot do.
The 5 steps
The method was designed as a simple way to make work feel less overwhelming. At its core are five steps:
- Choose one task.
- Set a timer, traditionally for 25 minutes.
- Work only on that task until the timer rings.
- Take a short break of about 5 minutes.
- After four focus sessions, take a longer break of 15 to 30 minutes.
A focus session is meant to be indivisible. If you get interrupted and have to switch to something else, the session does not count; you restart it later. If a quick idea pops up, write it down on your task list and return to the task in front of you.
How long is a session, a break and a full cycle?
In the classic setup, one focus session lasts 25 minutes and a short break 5 minutes. After the fourth session comes a long break of 15 to 30 minutes. A full cycle of four sessions, three short breaks and one long break therefore takes about 2 hours 10 minutes to 2 hours 25 minutes.
- Focus session: 25 minutes.
- Short break: 5 minutes.
- Long break: 15 to 30 minutes, after every four sessions.
- Full cycle: about 2 h 10 min with a 15-minute long break, or 2 h 25 min with a 30-minute one.
Tomatock starts with 25 / 5 and a 15-minute long break after every four sessions. You can change every number in Settings.
Why working in sessions helps
- Starting is easier. Committing to 25 minutes is much less daunting than committing to finishing a whole project.
- The clock keeps you honest. When you notice yourself drifting, you can see exactly how much of the session is left.
- Breaks are planned, so you do not have to earn them or feel guilty about them.
- Counting finished sessions shows how long tasks really take, which makes your future estimates better.
How to choose session and break lengths
The 25 / 5 rhythm is a starting point, not a law. The right length depends on the kind of work and on you.
- 15 / 5 or 20 / 5: for days when starting is hard, for tiring tasks, or when you are learning the method.
- 25 / 5 with a 15–30 minute long break every four sessions: the classic setup, good for most knowledge work.
- 50 / 10: for writing, programming, design and reading, where it takes time to build up context.
- 52 / 17: a popular alternative with longer breaks, for steady work where a 5-minute pause feels too short.
- 90 / 20: for rare deep-work blocks. Plan at most two or three in a day.
A simple test: if the alert usually arrives while you are still fresh and in the middle of good work, make sessions longer. If you often check the clock or stop early, make them shorter. Change one thing at a time and give it a few days.
Does it work? Pros and cons
It works for many people, but not for every kind of work or every day. It is a tool for starting and pacing, not a guarantee.
- Pro: it lowers the barrier to starting, because you only commit to one session.
- Pro: planned breaks help you keep a steady pace over several hours.
- Pro: counting sessions shows how long tasks really take.
- Con: a fixed alert can interrupt you just as you get into a flow; longer sessions help.
- Con: it fits poorly with work full of meetings or constant interruptions.
- Con: strict rules can feel rigid; keeping only the parts that help is fine.
What to do during breaks
A good break rests the parts of you that were working. After screen work, that usually means your eyes, your posture and your attention.
- Get up, walk around, stretch your back and shoulders.
- Refill your water or make a coffee or tea.
- Look at something far away to relax your eyes.
- Tidy your desk or do a small chore.
- Save social media and email for a long break, or keep them as their own task.
Try not to start anything during a short break that you will not be able to stop in five minutes.
Using a focus timer with ADHD
Many people with ADHD find a visible countdown helpful, and the classic rules are easy to adapt: shorter sessions, auto-start between phases, a focus view that hides the task list while a session runs, and a quiet alert sound. These are practical ideas, not medical advice.
Background tabs, phones and what a browser timer can do
Browsers slow down pages you are not looking at to save battery. For example, Chrome may only wake a hidden tab's timers about once per minute after it has been in the background for a while. A timer that simply counts seconds would drift or ring late.
Tomatock avoids that as far as a web page can:
- The time left is always calculated from the moment the session should end, never by counting ticks, so the clock is correct as soon as you look at it again.
- The alert sound is scheduled in advance, and a background worker wakes the page when time is up.
- If you allow notifications, you also get a system notification at the end of each session.
- If a session ended while the page was paused or closed, Tomatock records it when you return and tells you when it actually ended.
Limits you should know about
- Phones: when the screen locks or you switch to another app, mobile browsers usually suspend the page. The alert may only play when you come back. Keep the timer on screen and use the keep-screen-on option where your browser supports it.
- Sleep: when a computer goes to sleep, nothing in the browser runs until it wakes up.
- Closed tabs: a web page cannot play a sound after you close it. Leave the tab open while a session is running.
- Do Not Disturb and focus modes in your operating system can silence notifications. The sound still plays in the page.
- Sound only starts after your first click on the page, because browsers block audio that the user has not started.
- Battery savers and memory savers can pause background tabs. If you rely on the alert, exclude this site or keep the tab visible.
Where the method comes from
The Pomodoro Technique® was created by Francesco Cirillo in the late 1980s, when he was a university student looking for a simple way to study with more focus. He timed his work with a tomato-shaped kitchen timer, which gave the method its name. The official description of the method and its trademark information are on the official site, pomodorotechnique.com.
Tomatock is an independent timer and is not affiliated with Francesco Cirillo; the method's name is used here only to describe what the timer is for.
Common mistakes
- Skipping breaks because you are on a roll. You pay for it an hour later.
- Planning twelve sessions for a day that has room for six. Your estimate history will show you the real number.
- Using sessions for work that needs no focus. Answer quick messages in a batch instead.
- Treating a lost session as a failure. Restart and move on; the count is information, not a grade.

Frequently asked questions
What does pomodoro mean?
Pomodoro is the Italian word for tomato. The method got its name from the kitchen timer its creator used, which is why it is also called the tomato timer method.
Do I have to use 25 minutes?
No. Twenty-five minutes is the traditional length and a good default, but the idea is a fixed, focused block followed by a break. Choose the length that keeps you working well.
What if someone interrupts me?
If it can wait, note it and handle it after the session. If it cannot, stop the session, deal with it and start a fresh one later. An interrupted session is not counted as finished.
How many sessions should I do per day?
It depends on your work, but six to ten focused sessions is already a very full day. Many people do fewer and still get more done than before.
How long is a full pomodoro cycle?
With the classic numbers, four 25-minute sessions, three 5-minute breaks and one long break add up to about 2 hours 10 minutes with a 15-minute long break, or 2 hours 25 minutes with a 30-minute one.
Who created the Pomodoro Technique®?
Francesco Cirillo, in the late 1980s. He named it after the tomato-shaped kitchen timer he used as a student.
Why use a timer for focus at all?
A visible deadline makes it easier to start and harder to drift. Working in short, fixed sessions with planned breaks helps many people keep a steady pace for hours instead of burning out after one long stretch.
Is Tomatock affiliated with the creator of the method?
No. Tomatock is an independent free timer. The method's name is a registered trademark of its owner, and we use it only to describe what the timer is for.
Why did my alert come late?
Usually because the browser or the device paused the page: the screen was locked, the computer slept, or a battery or memory saver suspended the tab. Keep the tab open, allow notifications, and on phones keep the timer on screen.
