Pomodoro Timer

What this tool does

Pomodoro Timer runs the classic Pomodoro Technique, alternating focused work sessions with short breaks and a longer break every few rounds, cycling automatically with a sound cue at each transition, with fully adjustable durations saved for next time.

The Pomodoro Technique breaks work into focused intervals (traditionally 25 minutes) separated by short breaks, with a longer break after a set number of rounds, a simple structure that helps sustain focus and avoid burnout over a long work session.

This timer runs that cycle automatically: start it once, and it alternates between focus and break phases on its own, playing a sound cue at each transition and tracking which round you’re on, with every duration fully adjustable.

How to use Pomodoro Timer

1. Adjust the focus, short break, long break durations and rounds-before-long-break if you want something other than the defaults.
2. Press Start to begin the first focus session.
3. Work until the timer transitions automatically to a break, signalled by a sound cue.
4. Keep going through as many rounds as you need, or Reset to start over.

Tips for better results

• The traditional Pomodoro ratio is 25 minutes focus / 5 minutes short break, with a 15-30 minute long break every 4 rounds, a reasonable starting point if you’re not sure what durations to use.
• Keep this browser tab open and unmuted to hear the transition sound, if you’re working in a different tab or application, you’ll need to glance back occasionally or rely on the visual progress bar instead.
• Shorter or longer focus intervals both work depending on the task and your own attention span, there’s nothing magic about exactly 25 minutes, adjust it to whatever genuinely helps you sustain focus.
• Your duration preferences are saved automatically for next time, but the running timer itself resets if you close the tab, so finish a session in one sitting if possible.

Common use cases

• Structuring a long work or study session into focused intervals with built-in breaks.
• Building a sustainable focus habit using a well-known, simple time-management technique.
• Avoiding burnout during an extended period of deep work by enforcing regular breaks.
• Timing a specific task (writing, coding, studying) against a fixed focus interval.

Common mistakes to avoid

• Muting or minimising the tab and missing the transition sound cue, if you need to work elsewhere, check the visual countdown periodically instead.
• Skipping breaks because you feel "in the zone", the point of the technique is sustaining focus over a longer session, breaks are part of the design, not optional overhead.
• Using an unrealistically short focus interval for deep, complex work that genuinely needs longer uninterrupted stretches to get into flow; adjust the duration to match the actual task.
