Pomodoro Timer
A timer for the Pomodoro Technique: repeat 25-min focus sessions with short breaks. Auto-switches between focus and break.
About this tool
This Pomodoro timer helps you practice the time-management method of repeating "25 minutes of focus + a short break," with a longer break inserted every few sets (the Pomodoro Technique). It switches between work and break automatically and shows the remaining time and your progress at a glance. It runs entirely in your browser, so nothing about your sessions is sent to a server.
The Pomodoro Technique alternates short bursts of focus with short breaks, which tends to be less tiring and easier to sustain than grinding for hours at a stretch. Because it treats one focus session (one pomodoro) as a unit, it lowers the barrier to starting ("just one more pomodoro") and makes it easier to estimate work by time. It pairs well with tasks that need sustained focus, like studying, writing, and coding.
To use it, press start to begin the work phase; when time is up it switches to a break automatically. After the number of work sessions you set, a longer break replaces the usual short one. Progress is shown on the timer so you can see which phase you are in and how many pomodoros remain until the long break. The lengths of work and breaks and the interval for the long break can all be tuned to your own rhythm.
Your settings, such as work and break lengths, are saved in your browser (localStorage), so they are ready the next time you open the page. This storage stays in your browser and is not sent to a server. Note that clearing your browser history or site data will reset the settings.
How to use
- Set the focus, short break, and long break durations (in minutes) and the long-break interval as needed.
- Press Start to run the focus timer; when it reaches zero it switches to a break automatically (with an alert sound β pick the sound and volume under "Alert sound").
- A long break is inserted after the set number of focus sessions. Use Pause or Reset to interrupt or start over anytime.
FAQ
Is any usage data from this timer sent to a server?
No. The timer runs entirely in your browser. Settings like work length are saved in your browser (localStorage) and are not sent to a server.
What is the Pomodoro Technique?
A time-management method that alternates short focus sessions (25 minutes by default) with short breaks, inserting a longer break every few rounds. It helps maintain focus and avoid building up fatigue.
Can I change the work and break lengths?
Yes. You can set the work length, short break, long break, and how many work sessions occur before a long break. Adjust them to how long your focus lasts.
Are settings carried over next time?
Yes. Settings are saved in your browser, so you can start with the same configuration next time. Clearing your browser's site data returns them to defaults.
Does it keep running if I close the tab or switch tabs?
The timer runs on this page. It stops if you close the page, and some environments limit activity in hidden tabs. To be safe, keep the page open while focusing.
How do I know when a phase changes?
The remaining time and progress display show the current phase, so you can follow the switch from work to break and back to work on screen.
