What is the Pomodoro Technique?

The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. It uses a timer to break work into 25-minute focused intervals (called pomodoros) separated by 5-minute short breaks. After completing four pomodoros, you take a longer 15-minute break. This cycle helps maintain focus, reduce mental fatigue, and improve productivity.

Can I customize the timer durations?

Yes. While the classic Pomodoro durations are 25 minutes for work, 5 minutes for short breaks, and 15 minutes for long breaks, this timer lets you customize all three durations to suit your workflow. Some developers prefer 50-minute focus sessions with 10-minute breaks, while others work best with shorter 15-minute sprints.

About the Pomodoro Technique

The Pomodoro Technique is one of the most popular time management methods, especially among developers. Created by Francesco Cirillo in the late 1980s, it uses a simple cycle: work in focused 25-minute sprints (called "pomodoros"), then take a 5-minute break. After four pomodoros, reward yourself with a longer 15-minute break.

This technique works because it combats two common productivity killers: context switching and mental fatigue. By committing to a single task for 25 minutes, you train your brain to resist distractions. The regular breaks prevent burnout and keep your focus sharp throughout the day.
