Pomodoro Technique: How It Works, Does It Help and How to Make It Stick

The Pomodoro Technique is a way to work in short, focused blocks. You pick one task, set a timer for 25 minutes and work only on that task until it rings. Then you take a short break, usually about 5 minutes. After four of these blocks, called pomodoros, you take a longer break before starting again.

Where it comes from

Francesco Cirillo started developing the method in the 1980s as a university student, using a tomato-shaped kitchen timer to focus for short periods. Pomodoro is Italian for tomato. In his version, the timer is only the start. The full method also includes planning the day's tasks, estimating how many pomodoros each one takes, writing down interruptions and reviewing what happened (Cirillo, official site). Pomodoro® is a registered trademark of Francesco Cirillo.

How to do the Pomodoro Technique

1. Choose one task. Write it down. If it's big, break it into pieces that fit in one or two pomodoros.
2. Set the timer for 25 minutes. A kitchen timer, your watch or an app. If you use your phone, keep it out of reach.
3. Work on that task only. If something else pops into your head, write it on a piece of paper and go back to the task.
4. Stop when the timer rings. Put a tick next to the task.
5. Take a short break. About 5 minutes, away from the screen if you can.
6. After four pomodoros, take a longer break. Usually 15 to 30 minutes. Break lengths vary a little between versions of the method, so adjust them to how tired you feel.

A pomodoro is indivisible: if you stop halfway to do something else, that one doesn't count, and you start a new one when you're back.

A sample morning

This is an example schedule for one full cycle of the classic version.

That's 100 minutes of focused work in about two hours and twenty minutes.

Does it work? What the research says

There isn't much research on the Pomodoro Technique itself, but what exists is encouraging.

• Fixed breaks vs. your own breaks. In a study of 87 Dutch university students during a day of self-study, some took a 6-minute break after every 24 minutes, some a 3-minute break after every 12 minutes, and some chose their own breaks. The students who chose their own breaks studied in longer stretches and reported more fatigue and distraction and less concentration and motivation. All groups completed a similar amount of work, but the fixed-break groups did it in less time (Biwer et al., 2023).
• Short breaks in general. A meta-analysis of 22 study samples found that breaks of 10 minutes or less slightly increased energy and reduced fatigue. The effect on performance overall wasn't significant, and longer breaks helped performance more (Albulescu et al., 2022).
• The wider literature. A 2025 scoping review found 32 studies on the technique, and most reported positive results. Only three were randomized trials, though, and most were observational, so the evidence is still thin (Ogut, 2025).

So structured breaks seem to help you feel less drained without lowering how much you get done. The research doesn't show that 25 minutes is a magic number.

Pomodoro variations

The 12/3 and 24/6 splits are the ones tested in the study above. The 50/10 version is common but hasn't been tested in the same way, so try it and see how you feel at the end of the day.

Mistakes that ruin it

• Checking the phone during the pomodoro. It breaks the block, and having the phone in sight costs attention even when you don't touch it. People scored lower on attention tests with their own phone on the desk than with it in another room (Ward et al., 2017).
• Spending the break on a feed. Five minutes on social media rarely stays five minutes. Choose a break you can end easily.
• Skipping breaks when you're on a roll. The break is part of the method. If you keep skipping it, try longer blocks instead.
• Starting without a task. Decide what the pomodoro is for before you start the timer.
• Treating every interruption as an emergency. Write it down and deal with it in the next break unless it really can't wait.

Lock the apps during the block

LockTy blocks the apps you choose during the hours you set, so the phone can't pull you out of a pomodoro. You can also tie your apps to daily goals, like reading or focus time, and they unlock once you meet them.

Using it for studying

Pomodoros fit studying well because a chapter or a problem set breaks easily into 25-minute pieces. Plan before you sit down: "Pomodoro 1: summarize section 3. Pomodoro 2: do exercises 1 to 5." Use the long break for food or a walk, not for a second screen.

If your problem is getting started at all, start with the 12-minute version, or read our guide on how to stop procrastinating. If the phone is what keeps breaking your blocks, see how to stop phone addiction or our comparison of the best app blockers for iPhone.
