How are breaks counted?

Breaks fall between pomodoros, so a run of N pomodoros has N minus one breaks. Every set number of breaks becomes a long break and the rest are short breaks.

What are the default intervals?

The classic Pomodoro Technique uses 25-minute focus blocks, 5-minute short breaks and a longer 15-minute break after every four pomodoros. You can change all of these.

No. The calculation happens entirely in your browser and no data is sent anywhere.

Pomodoro estimator — plan your real session length

A “pomodoro” is a fixed block of focused work — classically 25 minutes — followed by a short break, with a longer break after every fourth one. This estimator adds up your focus time and all the short and long breaks so you know how long a block of pomodoros will actually take on the clock.

Enter the number of pomodoros and tweak the focus and break lengths to match your own routine. The total updates instantly and runs entirely in your browser.
