The Pomodoro Technique splits work into short, fixed blocks. You focus for 25 minutes, take a 5 minute break, and repeat. After four focus blocks you take a longer break of 15 to 30 minutes. Francesco Cirillo named it after the tomato-shaped kitchen timer he used as a university student.
The fixed length is the point. A deadline 25 minutes away is close enough to make you start and short enough that distractions can wait until the break. The break matters as much as the block: it keeps the fourth round as sharp as the first.
On this page the cycle runs itself. When a focus block ends, a chime plays and the break starts. When the break ends, the alarm rings and the next focus block waits for you to press Start, so it never runs while you are away from the desk.
