Pomodoro timer
Focus timer with work sessions, short and long breaks and a set length you choose, plus optional sound and desktop notifications.

The Pomodoro Technique, developed by Francesco Cirillo in the late 1980s, breaks work into focused intervals, traditionally 25 minutes, separated by short breaks of about 5 minutes, with a longer break after four intervals. This timer runs that cycle for you and moves from phase to phase on its own.
All four numbers are adjustable: focus length, short break, long break and how many focus sessions come before the long break. Many people use 50/10 for deep work or 15/3 when a task is hard to start. The counter under the clock shows where you are in the current set and how many sessions you have completed.
A double beep marks the end of each phase. "Enable notifications" asks your browser for permission (only when you click it) so a system notification appears even if the tab is in the background. The remaining time is also shown in the tab title.
How to use it
- Adjust the focus, short break and long break lengths and the number of sessions per set, or keep 25/5/15 and 4.
- Press Start. The timer runs the focus session, then the break, and continues automatically unless you untick auto-start.
- Use Pause to interrupt, "Skip to next" to end a phase early, and Reset to return to the first session.
- Optionally enable notifications and the beep so you notice phase changes from another tab.
Frequently asked questions
What are the standard Pomodoro lengths?
Cirillo's original method uses 25 minutes of work and a 5-minute break, with a longer break of 15 to 30 minutes after four pomodoros. The defaults here are 25, 5 and 15 minutes with a long break after four sessions.
Why did notifications not appear?
Your browser or operating system may block them. If the button says notifications are blocked, allow them for this site in the browser's site settings. Focus modes or Do Not Disturb on the device also hide them.
Does skipping a focus session count it as completed?
Yes. Skipping ends the phase and moves the cycle forward exactly as if the time had run out, so the long break still comes after the set number of sessions.
Will it keep time in a background tab?
Yes. Each phase ends at a fixed moment, so the countdown is right when you come back. Browsers throttle background timers, so the beep or notification may be a little late when the tab is hidden.
