Work in focused sessions with short breaks and a longer break every four rounds, with a tone at each change and a count of what you finished today.

This Pomodoro timer runs the classic focus-and-break cycle: a 25-minute work session, a 5-minute short break, and a 15-minute long break after every fourth session. All four numbers are editable, so you can run 50/10 deep-work blocks or 15/3 sprints just as easily. It is for students, writers, developers, and anyone who works better with a visible clock and enforced rest. The page keeps a count of the focus sessions you complete today and the total minutes focused, stored only in your browser, and the current settings are kept in the page address so a bookmark restores your preferred rhythm.
The timer is a small state machine with three phases: focus, short break, and long break. Finishing a focus session increments the completed count; if that count is a multiple of the long-break interval (4 by default) the next phase is a long break, otherwise a short break. Finishing any break returns to focus. The countdown itself compares a stored end time against the system clock several times a second, so it does not drift in a background tab. At each phase end the page plays a tone through the Web Audio API and alternates the tab title, then either auto-advances to the next phase or waits for you to press Start. Today's completed sessions are saved in localStorage under the current date and reset automatically on a new day.
It is a time-management method developed by Francesco Cirillo in the late 1980s, named after a tomato-shaped kitchen timer. You work in fixed intervals, traditionally 25 minutes called pomodoros, separated by short 5-minute breaks, with a longer break of 15 to 30 minutes after every four intervals. The fixed length makes starting easier and the breaks reduce fatigue.
Yes. Focus, short break, long break, and the number of sessions before a long break are all editable in the settings panel. Changing a value while a phase is running restarts the current phase with the new length. Many people use 50/10 for deep work or 15/3 for tasks they find hard to start; the technique matters more than the exact numbers.
In another tab, yes: the countdown is computed from a fixed end time, so it stays accurate and the alarm fires when the phase ends. On a locked phone or a suspended laptop the browser may pause JavaScript entirely, so leave the page visible or use the browser notification option if your device supports it.
In your browser's localStorage, tied to today's date, so it resets each day and is never sent anywhere. Clearing site data, using a private window, or switching browsers will show zero. The counter records only focus sessions that ran to completion; skipped sessions are not counted.
