Pomodoro Timer
25-min focus → 5-min short break → 25-min focus → … with a 15-min long break every 4 cycles. A focus technique to keep concentration up and burnout down.
Durations
How to Use
Tweak focus, short break, long break, and cycles-per-long-break (defaults: 25 / 5 / 15 / 4).
Hit Start and the focus phase counts down. Use Pause, Skip, and Reset to control flow.
When time is up, an audio cue plays and the next phase (break or focus) starts automatically. The current phase is shown by label and color.
FAQ
What's the Pomodoro technique?
Coined by Francesco Cirillo in the 1980s. One "pomodoro" = 25 min focus + 5 min break; after 4 you take a longer 15–30 min break. Short bursts keep focus up and prevent burnout.
Why 25 minutes?
Cirillo first used a kitchen timer shaped like a tomato (pomodoro in Italian) set to 25 min. It happens to fit within the 20–30 min average attention span, so it stuck. You can change it freely here.
I don't hear the alert.
Browsers only allow audio after a user gesture — once you press Start, sounds work. On mobile, even silent mode (vibrate) blocks audio; turn it off. Use the bell icon to mute.
Does it work in a background tab?
Browsers throttle setInterval in background tabs, but the timer uses real-clock time and re-syncs when you return. Accuracy is preserved.
Is anything sent to a server?
No. All timer logic stays in your browser; nothing leaves the page.
