Pomodoro Technique
The Pomodoro Technique is a popular time management method:
- Work for 25 minutes — Focus on a single task without interruption
- Break for 5 minutes — Step away, stretch, rest your eyes
- Every 4 pomodoros — Take a longer 15-30 minute break
Click the "25 min" preset button above to quickly start a Pomodoro work session.
