Pomodoro Timer
A focus-and-break timer using the Pomodoro method, with adjustable times and a sound alert at the end of each stage.
How it works
The Pomodoro technique splits work into blocks: a period of focused work followed by a short break. The classic pattern is 25 minutes of focus and 5 of rest, but you can adjust both times as you like.
In this tool, you start the timer and it counts down the focus time. When it reaches zero, a sound alert plays and it automatically moves to the break; when the break ends, it returns to a new focus cycle. A counter tracks how many focus blocks you've completed, which helps you follow your progress through the day.
The controls are straightforward: start, pause and reset. The focus and break times are set with sliders, which lock while the timer runs to prevent accidental changes mid-cycle. Everything works in the browser, with nothing to install.
When to use
The Pomodoro method is one of the best-known productivity techniques precisely because it's simple and works for many people. It's good for studying, writing, coding, reviewing — any task that demands concentration and where procrastination hits hard.
The idea is that short, defined blocks lower the resistance to starting ("it's only 25 minutes") and regular breaks prevent burnout. It's especially useful for people who get distracted easily, for tackling big tasks by slicing them into parts, and for building a sustainable work rhythm over hours. It also gives a real sense of how long an activity takes, by counting the cycles.
Practical examples
A study session
To study in the afternoon, keep the default of 25 minutes of focus and 5 of break. With each completed block, the counter goes up. After four cycles, it's worth taking a longer break to really rest before starting again.
Tasks that need deep focus
For activities that need more immersion, like coding, raising the focus to 50 minutes with a 10-minute break often works better — longer blocks let you get deeper into the task before the interruption.
Common mistakes
The most common mistake is skipping the break. Running one focus block straight into the next without resting seems productive, but usually leads to fatigue and a drop in performance. The break is part of the method, not wasted time — it's what makes the rhythm sustainable.
Another slip is the opposite: turning the break into a long distraction. A five-minute break that becomes half an hour on your phone breaks the momentum. The break is for resting the mind, not swapping one distraction for another.
There's also the matter of poorly tuned times. Blocks that are too long tire you out before the break; too short and you never get into the rhythm. The ideal is to experiment until you find the combination that works for you and the type of task — there's no single right number for everyone.
Frequently asked questions
What is the Pomodoro technique?
It's a productivity method that alternates periods of focused work with short breaks. The classic format uses 25 minutes of work and 5 of rest, repeated in cycles.
Can I change the focus and break times?
Yes. The sliders adjust the focus and break minutes to your preference. They lock during the countdown so they don't change by accident.
Does the timer alert me when time is up?
Yes. At the end of each stage, a short sound alert plays and the timer automatically switches from focus to break, or from break to a new focus cycle.
Do I need to keep the tab open?
Yes. Since everything runs in the browser, the timer works while the page is open. Closing the tab ends the running countdown.
