Frequently Asked Questions
Why is 25 minutes the Pomodoro focus length?
The Pomodoro Technique, developed by Francesco Cirillo, uses 25-minute focused work sessions followed by 5-minute breaks. Research shows this interval optimises concentration and reduces mental fatigue.
Why 25 minutes for a Pomodoro?
Francesco Cirillo chose 25 minutes in the late 1980s based on his own focus-and-fatigue experiments using a tomato-shaped kitchen timer (hence "pomodoro" — Italian for tomato). Research has since shown the 20–30 minute range is the sweet spot for sustained attention before mental fatigue starts to compound.
Can I stream this timer on Twitch or YouTube?
Yes. Enable transparent background in settings and paste the URL as an OBS browser source to add it as a stream overlay. Custom colours make it fit any stream aesthetic.
