How it works
The Pomodoro technique alternates focused work with short breaks. This timer runs a Work → Short Break cycle, and after a configurable number of rounds it inserts a Long Break. Each phase length is adjustable in settings, which persist in your browser via localStorage. Rather than counting down a variable that drifts when a tab is backgrounded, it stores the target end timestamp and computes the remaining time from the real clock, so it stays accurate. A soft tone marks each phase change.
Common use cases
- Working in disciplined 25-minute blocks to beat procrastination.
- Pacing study sessions with regular breaks to retain more.
- Time-boxing chores or writing with a clear start and stop.
Frequently asked questions
Does the timer keep running if I switch tabs?
Yes. It tracks the target end time against the real clock instead of decrementing a counter, so background-tab throttling does not slow it down — the time shown is always correct when you return.
Can I change the work and break lengths?
Yes. The settings panel lets you set work, short-break, and long-break minutes plus how many rounds precede a long break. Your choices are saved in the browser for next time.
Will it make a sound?
A short tone plays at each phase change using the Web Audio API, and the page title shows the countdown. No notification permission or server is involved.
