Pomodoro Timer — a 25/5 online focus and study timer
A Pomodoro timer that repeats 25 minutes of focus and 5 minutes of rest four times, then gives you a long break. Change the focus, short break and long break lengths and how often the long break comes, and choose whether the next round starts by itself or waits for you, with a sound and a notification at the end. It counts toward a fixed end time, so it stays accurate while you use other tabs or minimise the window, and it keeps today's and the last seven days' focus log in this browser. White noise, rain and other focus sounds can play while you work. Nothing you enter is sent to a server.
Pomodoro Timer
A time-management timer: focus for 25 minutes, rest for 5, repeat four times, then take a 15-minute long break. It stays on time while you use other tabs or minimise the window, and tells you with a sound and a notification when each round ends.

Keep screen onStops the screen from sleeping while the timer runs
On a phone, switching to another app or turning the screen off can put the page to sleep, so the sound may come late. The timer still counts toward a fixed end time, so it's correct again as soon as you come back. For anything important, turn on "Keep screen on".

FAQ

What is the Pomodoro Technique?
It's a time-management method: focus on a single task for 25 minutes, rest for 5, repeat that four times, then take a longer 15–30 minute break. Francesco Cirillo started it in Italy in the late 1980s with a tomato-shaped kitchen timer, hence the name "pomodoro", Italian for tomato. If 25 minutes feels long, shorten it in the settings; for deep work you can stretch it to 50 minutes of focus and 10 of rest. Pomodoro Technique® is a registered trademark of Francesco Cirillo.
Does it stay accurate if I switch tabs or minimise the window?
Yes. Browsers wake timers in hidden tabs only once a second or even once a minute, so a timer that subtracts one every second drifts by minutes. This one fixes the end time when you press start and compares it with the current time on every update, so the remaining time is right even if it wakes late, and with auto-start on, the next round is counted from the moment the previous one actually ended. On a phone, though, turning the screen off or switching apps can pause the page itself, so the sound may come late. In that case, turn on "Keep screen on".
I don't get a sound or notification when a round ends.
Browsers don't let a page make sound until you've clicked on it once. Sound works from the moment you press Start, and you can check the volume with "Preview" in the settings. For notifications, turn on "Notify me when a round ends" and allow the permission the browser asks for; if you blocked it before, allow notifications again in the site settings to the left of the address bar. Safari on iPhone and iPad only sends web notifications from sites added to the Home Screen.
Can I play white noise or rain sounds?
Tap "Sound" under the timer and pick white noise, brown noise, rain or clock ticking, and it plays while the timer runs. By default it plays only during focus rounds and stops for breaks; turn off "Only during focus" to keep it going through breaks. The sound isn't a recording — your browser generates it on the spot, so it uses no data — and its volume is set separately from the end-of-round sound. On a phone, the browser may stop the sound if you turn off the screen or switch to another app.
Where is my focus history stored?
Only in this browser (localStorage); nothing is sent to a server. It keeps the number of sessions and minutes per day for the last 90 days, and the count per task for the last 14 days, and isn't shared with other devices or browsers. It disappears when you press "Clear history" or clear the browser's site data. Your task note and timer settings are kept in the same place.
