25 minutes of focus, a 5-minute break, and a longer break every 4 rounds by default — but every number is yours to change. Runs in the browser, with no account and no app to install.
Break an open-ended task into timed sprints with a forced break in between, instead of sitting down with no end in sight.
The Pomodoro technique is already a study-hall staple — this runs in any browser, so it works on a school or library computer with nothing to install.
The fixed round length and audible chime remove the guesswork of "how long have I actually been doing this," without needing a separate app.
With Auto-start on, focus and break rounds chain on their own — set it up once at the start of a work block and let it run.
Four steps to a running Pomodoro session.
Focus, Short break, and Long break minutes, plus how many rounds happen before a long break — all editable, all saved for next time.

Choose Bell, Marimba, Positive Ding, or Confirm Tone under Chime, or mute it entirely with the Sound toggle.

The questions that come up most about this technique.
A time-management method built around fixed focus blocks — traditionally 25 minutes — each followed by a short break, with a longer break every few rounds. The structure helps avoid both burning out and losing track of time.
Yes — Focus, Short break, and Long break minutes, plus how many rounds happen before a long break, are all editable in Settings and saved for next time.

Yes — four chime sounds under Chime in Settings, or turn Sound off entirely for a silent timer.
Yes, the countdown keeps running in a background tab. Turn on Keep Screen On if you also need the display to stay lit through the whole session.
