What is the Pomodoro Technique?

The Pomodoro Technique is a time-management method developed by Francesco Cirillo in the late 1980s. You work in focused intervals (traditionally 25 minutes), then take a short break (5 minutes). After four intervals you take a longer break (15-30 minutes). The method reduces mental fatigue, minimizes interruptions, and makes large tasks feel manageable.

Cirillo found that 25 minutes is long enough to make meaningful progress on a task but short enough to maintain high concentration without mental drift. Research on attention spans supports intervals in the 20-30 minute range for sustained focus. That said, you can freely adjust the duration in Settings to fit your personal work rhythm.

Can I customize the intervals?

Yes. Open the Settings panel and change focus duration, short break duration, long break duration, and how many sessions trigger a long break. Your settings are saved automatically in your browser and will be restored the next time you visit.

Does the timer run in the background?

The timer runs in JavaScript, so it continues as long as the browser tab is open. The remaining time is shown in the tab title so you can monitor it from other tabs. If you close or reload the tab the current session will reset. For most users, keeping the tab open in the background is sufficient.

Summary

Stay focused and productive using the Pomodoro Technique. Customize work and break durations, track your daily sessions, and get audio cues when it is time to switch.

How it works

Set your desired focus and break durations in the Settings panel (defaults: 25 min focus, 5 min short break, 15 min long break).
Press Start to begin your first focus session. The countdown ring and MM:SS display will start ticking down.
When the timer reaches zero, a beep sounds and the timer automatically switches to a break. Press Start to begin the break.
After the configured number of focus sessions (default 4), a long break is offered instead of a short break.

Use cases

Studying: break long study sessions into focused 25-minute blocks to improve retention and reduce fatigue.
Coding: use focused intervals to write features without distractions, then step away during breaks to avoid burnout.
Deep work: protect high-concentration tasks from interruptions by committing to timed, distraction-free sprints.
