Keeps time in a background tab
The countdown is worked out from the moment the session is due to end, not by counting seconds, so a hidden or busy tab cannot make it run slow. The time left also shows in the tab title.
Round lengths you choose
Start with 25 minutes of focus, 5-minute breaks and a 15-minute break after four rounds, then change any of them. Sessions can wait for you or start one after another automatically.
A chime and a log of your day
A chime made in your browser marks the end of every session, with a volume control and mute. An optional desktop notification and a list of today's finished sessions keep track for you.

Frequently Asked Questions
What is the Pomodoro Technique?
It is a way of working in short, timed rounds. You focus on one task for 25 minutes, take a 5-minute break, and after four rounds take a longer break of 15 to 30 minutes. Francesco Cirillo developed it in the late 1980s and named it after his tomato-shaped kitchen timer; pomodoro is Italian for tomato.
Can I change the 25-minute focus length?
Yes. Focus sessions, short breaks and long breaks can each last from 1 to 180 minutes, and the long break can come after 2 to 10 focus sessions. A new length applies at once to a session that has not started. A session already in progress keeps its length, and the change applies from the next one.
Does the timer stay accurate when the tab is in the background?
Yes. Browsers slow down timers in hidden tabs, so this one stores the time the session ends and shows the difference between then and now. The chime is scheduled ahead on the browser's audio clock, so it does not depend on those timers. The tab title and the desktop notification do, and can arrive late while the tab is hidden.
What happens if I reload or close the page?
The end time of a running session is saved, so reopening the page in the same browser picks it up with the right time left. If the session ended while the page was closed, it is recorded as finished and the timer moves on to the next one. Nothing can chime or notify you while the page is closed, and after a reload browsers allow sound only once you have clicked the page.
How do the chime and the desktop notification work?
The chime is generated in your browser, so there is no sound file to load. Set its volume, mute it, or play it with Test chime. The desktop notification is optional: your browser asks for permission only when you turn the option on. If you refuse, or notifications are blocked for the site, the option stays off and the timer works as before.
What do Reset and Skip do?
Reset puts the current session back to its full length and stops it. Skip moves to the next session without recording the current one. A skipped focus session is not added to today's totals and does not count toward the long break.
What is counted in today's totals?
Completed focus sessions and their minutes. Breaks appear in the log but are not counted. A session belongs to the day it ends on, using your device's local date, and the log starts again each day; earlier days are not kept. The log lists up to the latest 100 sessions, and a focus session shows what you typed in the Working on box.
Is anything saved or uploaded?
Nothing is uploaded and there is no account. Your settings, today's log, the task label and a running timer are stored in this browser on this device, which is how the timer survives a reload. Select Clear saved data to erase them. They do not sync to other devices and are removed if you clear your browser data.
