Work in focused 25-minute sprints with short breaks in between, using the popular Pomodoro method. The timer counts down your work block, dings, then gives you a break — and after four work blocks you earn a longer rest. Press start and let it guide your focus. Everything runs in your browser.
About this Pomodoro timer
The Pomodoro Technique is a simple way to stay focused: you work in short, timed blocks — usually 25 minutes, called a "Pomodoro" — then take a 5-minute break. After four work blocks you take a longer break of around 15 minutes, and then the cycle repeats. This timer handles the whole rhythm for you: it counts down each phase, plays a gentle chime when one ends, automatically moves to the next phase, and keeps a tally of how many work sessions you have completed. You can change the work, short break and long break lengths to fit how you like to work. It is popular with students, writers, developers and anyone who wants to beat procrastination.

Frequently asked questions
- What is the Pomodoro Technique?
- It is a way of working in focused blocks of about 25 minutes, called Pomodoros, separated by short breaks. After four work blocks you take a longer break. It helps you stay focused and avoid burning out.
- Can I change the 25, 5 and 15 minute lengths?
- Yes. The work, short break and long break lengths are all number inputs you can edit. The defaults are 25, 5 and 15 minutes, but you can set whatever suits you.
- When does the long break happen?
- After every fourth completed work session the timer gives you the long break instead of a short break, then the cycle starts again.
The science of interval productivity
The Pomodoro Technique operates on the principle that the human brain cannot maintain peak concentration indefinitely. By segmenting work into discrete blocks, you create a sense of urgency that discourages multitasking and encourages deep focus. The method relies on a simple structure: a dedicated period of intense work followed by a brief, mandatory recovery period. This rhythmic oscillation between effort and rest prevents cognitive fatigue and helps maintain consistent output throughout a session.
Francesco Cirillo developed this system in the late 1980s using a tomato-shaped kitchen timer as his primary tool. The core formula involves a single work interval, a short break, and a recurring long break after a set number of cycles. The technique functions by treating time as a finite resource, forcing the user to prioritize tasks within the constraints of the timer. By externalizing the passage of time, the system removes the mental burden of tracking progress manually.
The most frequent mistake users make is treating the short break as an opportunity to check email or browse social media. These activities continue to tax the brain, preventing the recovery required for the next work interval. Effective breaks must be non-stimulatory, such as stretching, walking, or looking away from screens. Failing to step away entirely often leads to diminishing returns as the day progresses, which undermines the primary goal of the method.
