The Pomodoro Technique
The Pomodoro Technique is a time management method that splits work into rounds of 25 minutes on a single task, each followed by a short break, with a longer break after every four rounds. Francesco Cirillo created it in the late 1980s and named each round a pomodoro, Italian for tomato, after the kitchen timer he used.
Why 25 minutes works
The interval is short enough to feel approachable, which matters because starting is the hardest part, and long enough to get real traction. The ticking deadline creates a gentle urgency that crowds out procrastination. The guaranteed break removes the temptation to "just check something" in the middle of a task, since you know a pause is coming soon anyway.
In a 2023 study of 87 university students, those who took breaks on a fixed schedule, including a group that studied for 24 minutes and rested for 6, reported less fatigue and distraction and more concentration and motivation than students who decided for themselves when to stop, and they appeared to get the same amount done in less time. A 2011 lab experiment points the same way, finding that brief, occasional switches to another task kept attention from fading over a long task.
The mistake that makes it fail
It is easy to set the timer and leave your phone right there, fully unblocked. Stop to answer the first notification and, by Cirillo's own rules, that pomodoro no longer counts. "A Pomodoro can't be interrupted; it marks 25 minutes of pure work," he wrote in his 2007 guide to the technique, and one that is definitively interrupted "should be considered void, as if it had never been set." A timer manages your time, but it does nothing to defend it.
The fix is to pair the timer with a blocker. When you start a pomodoro, block your distracting apps for those 25 minutes as well as silencing the phone. With Lock In Squad, you set the interval and lock in, and your blocked apps stay closed until you deliberately hold the Lock Out button to end the session, at the break or before it.
Make it a habit
The technique compounds when it is daily. Track your pomodoros and keep a streak, because the payoff goes beyond a better day today to the kind of focus habit that carries across a whole semester or quarter.

Questions
What is the Pomodoro Technique and how does it work?
It is a way of working in timed rounds that makes focus countable. Each finished pomodoro earns an X next to its task, and after a few days the tally shows how many rounds each kind of work really takes. Cirillo made that the method's first objective, finding out how much effort an activity requires.
Does the Pomodoro Technique work for ADHD?
We could not find a controlled trial of it in people with ADHD, so treat it as an experiment. If 25 minutes feels too long, start with 10 or 15, which is close to how Cirillo began, by betting himself he could study for 10 minutes. For anything beyond study habits, talk to your clinician.
How do you use the Pomodoro Technique for studying?
Break each subject into tasks that fit one or two pomodoros, such as five practice problems or one section to summarize, and list them before you start. Work down the list in order, and stop when the timer rings, even mid-problem. Plan the next day's list during the last break, while you still remember where you stopped.
What are the steps of the Pomodoro Technique?
Choose one task and write it down. Set a timer for 25 minutes and work only on that task until it rings. Take a break of about 5 minutes, then start the next pomodoro. After every four pomodoros, take a longer break of 15 to 30 minutes, then begin a new set.
