What Is the Pomodoro Technique?
The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. The core idea is simple: work in focused 25-minute blocks (called "Pomodoros"), then take a 5-minute break. After four Pomodoros, take a longer break of 15–30 minutes.
This structured approach reduces mental fatigue, keeps you focused, and makes large tasks feel manageable. It's widely used by students, developers, writers, and anyone who needs to concentrate for extended periods.

Frequently Asked Questions
Does the timer work if I switch to another tab?
Yes. The timer continues running in the background. Modern browsers keep JavaScript timers active even when a tab is not visible. The alert sound will play when time is up, though some browsers may throttle background tabs — keep the volume on for best results.
Why 25 minutes for a Pomodoro?
Francesco Cirillo chose 25 minutes because it's long enough to make meaningful progress on a task but short enough to maintain high concentration. Research in cognitive science supports working in intervals of 20–30 minutes as optimal for sustained focus without mental fatigue.
Can I set a custom timer duration?
Yes. Click the Custom tab and enter any combination of hours, minutes, and seconds. This lets you use the timer for anything — cooking, workouts, study sessions, presentations, or any interval you need.
