What is the Pomodoro Technique?

The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. It involves working in focused 25-minute intervals (pomodoros) separated by 5-minute short breaks. After four pomodoros, you take a longer 15–30 minute break.

Can I change the timer durations?

Yes. Click the Settings icon to adjust work duration (1–60 minutes), short break duration (1–30 minutes), long break duration (1–60 minutes), and the number of sessions before a long break (2–8).

Where are my statistics saved?

Statistics are saved in your browser's localStorage under a unique key. They persist across sessions on the same device and browser but are not synced to other devices. You can reset them at any time using the Reset Stats button.

Why does the chime not play?

Browsers require a user interaction before playing audio. Make sure you have clicked Start at least once. Some browsers also require audio permissions — check your browser settings if the chime is still silent.

このツールについて

An advanced Pomodoro technique timer with full configuration options for work duration, short break, long break, and the number of sessions before a long break. A Web Audio API chime plays automatically at the end of each phase so you never miss a transition. The session log records each completed session with its type and timestamp. Daily statistics — total sessions completed and total focus time — are persisted in localStorage so your progress is saved across browser visits. Reset statistics at any time. The Pomodoro technique helps you maintain focus by breaking work into timed intervals separated by short rest periods.
