Questions people ask
The things that come up about pomodoro timers, answered plainly.
What is the Pomodoro technique?
Francesco Cirillo's method from the late 1980s: work for 25 minutes, break for 5, and take a longer 15- to 30-minute break every four rounds. The name is from the tomato-shaped kitchen timer he used.
Can I change the lengths?
All of them — work, short break, long break and how many rounds before the long one. The settings live in the address bar, so a link restores your configuration.
