Free online Pomodoro timer. Boost your productivity with the Pomodoro technique — 25-minute work sessions, short and long breaks, task tracking, and browser notifications.
No completed pomodoros yet. Start your first session!
The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. The basic structure: work in focused 25-minute intervals (called 'pomodoros' from the Italian word for tomato, named after Cirillo's tomato-shaped kitchen timer), separated by 5-minute breaks. After four pomodoros, take a longer 15-30 minute break. The structured intervals encourage sustained focus and prevent the fatigue that comes from longer continuous work.
This timer implements the standard Pomodoro pattern with configurable work and break durations. Notifications signal interval transitions. A simple pomodoro counter tracks how many work intervals you've completed in the session. Visual and audio cues mark the start and end of each interval.
All state runs in your browser. Closing the tab loses session data unless persistence is enabled. The intent is a simple lightweight tool for use during a single work session, not a comprehensive task tracker.
Many people work better in short bursts than in long marathons. The Pomodoro structure exploits this by enforcing 25-minute focus windows followed by mandatory breaks. The breaks prevent burnout; the focus windows prevent shallow work.
The timer also provides a forcing function for starting. Looking at a long task is paralyzing; committing to just one 25-minute block is approachable. Often the first pomodoro builds enough momentum that the rest of the task continues without willpower.
Set durations, click start, follow the cycle.
The timer uses setInterval or requestAnimationFrame to update the displayed countdown. Audio notifications use the Web Audio API or HTMLAudioElement to play interval-end sounds.
Notifications via the browser Notification API can alert when the timer ends even if the tab is in the background. Permission must be granted by the user.
Persistence: localStorage can save the current session's pomodoro count, durations, and elapsed time so a tab refresh does not lose progress. Implementation varies by tool.
