About Pomodoro Timer
The Pomodoro Timer helps you stay focused using the Pomodoro Technique: 25 minutes of focused work followed by a 5-minute break. After four cycles, take a longer 15–30 minute break.
All durations are customizable: set your preferred work interval, short break, long break, and the number of cycles before a long break. A sound notification alerts you when each session ends.
The Pomodoro Technique was developed by Francesco Cirillo in the late 1980s and is one of the most popular time management methods. It reduces the impact of internal and external interruptions on focus and helps build a sustainable work rhythm.

Why does the Pomodoro Technique use 25-minute intervals?
Francesco Cirillo found 25 minutes optimal for sustained focus with his kitchen timer (shaped like a tomato — 'pomodoro' in Italian). Research supports short work bursts with regular breaks for maintaining attention.
