Pick a focus split
Each preset only sets the starting lengths. You can change every number in the settings panel, and the timer remembers your choice for the next visit.
- 25/5 — classic Pomodoro Twenty-five minutes of focus, a five-minute break, and a longer fifteen-minute break every four rounds.
- 50/10 — deep work Fifty minutes on, ten minutes off. A longer block for writing, coding and design work that needs warm-up time.
- 52/17 — steady rhythm Fifty-two minutes of work followed by seventeen minutes away from the screen, with a seventeen-minute long break.
- 90/20 — ultradian block Ninety minutes of uninterrupted concentration and a twenty-minute break, for work that is hard to restart.
- 45/15 — balanced session Forty-five minutes on, fifteen minutes off. Fits a lesson period, a study hour or a focused gym routine.
How the Pomodoro Technique works
The method is deliberately simple: one task, one timer, one short break. You work in a fixed block called a pomodoro, rest briefly, then start again. After a set number of rounds, you take a longer break. This timer tracks the rounds for you and switches between focus, short break and long break automatically.
- Pick a single task and write it down. A written task is much harder to swap for a more comfortable one halfway through.
- Start the focus block and work only on that task. If something else appears, note it for later instead of switching.
- When the timer ends, stop even if you are in flow. Stand up, look away from the screen, and take the short break.
- After the preset number of rounds, take the longer break before beginning the next set.
Why short focus blocks help
Long stretches at a desk feel productive, but attention fades quietly. Fixed blocks make the cost of distraction visible and the reward for finishing immediate.
- Starting is easier when the commitment is minutes rather than an open afternoon.
- Breaks are scheduled rather than stolen, so you return to the task with a clearer head.
- A count of finished rounds is an honest measure of effort, which makes planning tomorrow more realistic.
- The rhythm protects energy: short rests limit the fatigue that builds during long reading or meeting-heavy days.
Planning a deadline instead? Count down with the countdown timer. Or time a single task with the online timer.
