Pomodoro Timer

The Pomodoro Timer is a free, browser-based productivity timer built specifically for developers and knowledge workers. It implements the Pomodoro Technique, a time management method developed by Francesco Cirillo in the late 1980s that uses timed intervals (traditionally 25 minutes of focused work followed by short breaks) to improve concentration and prevent burnout.

This tool provides fully customizable work durations, short break periods, and long break intervals. After every four work sessions, a longer break is automatically scheduled. The visual progress circle gives you an at-a-glance view of how much time remains, and an audio notification (using the Web Audio API) alerts you when each session ends.

All processing runs entirely in your browser. No data is sent to any server, and no account or signup is required. Your session history is maintained in memory for the current browser session, making it perfect for tracking your daily focus time without any privacy concerns.

The timer pairs well with the Epoch Countdown for deadline tracking and the Timestamp Converter for logging your sessions with precise timestamps. If you work across time zones, the Timezone Converter can help you coordinate Pomodoro sessions with remote team members.

1. Click Start to begin a 25-minute work session. The progress circle animates as time counts down.
2. When the session ends, an audio beep plays. The timer automatically switches to a Short Break (5 minutes).
3. After completing four work sessions, the timer schedules a Long Break (15 minutes) instead.
4. Use the Pause button to temporarily stop the timer, and Resume to continue from where you left off.
5. Click Skip to move to the next session without waiting for the current one to finish.
6. Adjust Work Duration, Short Break, and Long Break times in the Settings panel to customize your intervals.
7. Toggle Auto-start next session to automatically begin the next session when the current one ends.
8. Check the Session History table and stats cards to review your completed sessions and total focus time. Press Ctrl+Shift+C to copy the current timer value.
