How to use the pomodoro timer
- Press start to begin a focus session.
- Work until the timer sounds, then take the break it moves you to.
- Adjust the session lengths if 25/5 does not suit the work.
About this tool
The pomodoro technique is 25 minutes of single-task work followed by a short break, with a longer break after four rounds. The value is less in the 25 minutes than in the boundary: a fixed, short commitment makes starting easier, and the enforced breaks stop the slow drift into fatigue.
The timer moves to the break automatically, because the break is the part people skip and the part that makes the rhythm sustainable. Session lengths are adjustable — 25/5 is the convention, not a rule, and longer blocks suit some work better.
Timing is measured against the clock rather than counted in ticks, so switching tabs does not slow it down.
Common uses
- Getting started on a task you have been avoiding.
- Structuring a long study session.
- Keeping a meeting to time.
Frequently asked questions
- Why 25 minutes?
- It is short enough to commit to and long enough to get somewhere. Nothing is special about the number — adjust it if a different block suits your work.
- Will it keep time if I switch tabs?
- Yes. Elapsed time comes from the clock, not from counting intervals, so background throttling does not slow it. The sound needs the tab to still be open.
