A focus timer that grows with you
Pomodoro gives everyone the same 25 minutes. This timer starts at your current span and stretches it a little after good sessions – endurance training for concentration.
How it works
- 1Start – the timer suggests a length that fits your recent sessions.
- 2One task, one window. Phone out of reach.
- 3When a thought pops up (“just check email …”), note it in one line and keep working – at the end it can become a to-do.
- 4At the end you rate from 1 to 5 how focused you were.
- 5Good session: a few minutes longer next time. Broke off: a bit shorter.
Why grow instead of 25 minutes
If you can manage ten minutes in a row today, 25 will fail – and mostly teach you that concentration doesn’t work. Small steps just beyond your limit keep the success rate high and still stretch your span. The length moves between 5 and 90 minutes.
Park distractions
The urge to check something often fades after a minute – if you don’t give in. Noting it gives it a place without breaking your work. More in the focus guide.
