Pomodoro Focus Timer

The Pomodoro Technique was created by Francesco Cirillo in the late 1980s and named after the tomato-shaped kitchen timer he used as a student. The idea is simple: work in a single focused sprint — a "pomodoro" — then take a short break, and after four sprints take a longer one. Splitting the day into timed chunks makes big tasks feel approachable and gives your attention a clear finish line to aim for.

This timer runs that rhythm for you. The default is a 25-minute focus block, a 5-minute short break and a 15-minute long break, but every length is adjustable. It auto-cycles — a long break arrives after every fourth focus session — and the ring counts down while the browser tab title mirrors the clock so you can glance at it from another tab. When a session ends you get an optional desktop notification.

Because the countdown is anchored to a wall-clock deadline rather than a ticking counter, it stays accurate even when a background tab is throttled by the browser. Your finished pomodoros, today's focus time and your all-time total are kept in this browser's local storage, so your streak is waiting the next time you open the page. Nothing is uploaded and no account is needed.
