Pomodoro Timer
Stay focused with timed work sessions and breaks using the Pomodoro Technique.

Session Lengths (minutes)
What is it?
The Pomodoro Technique breaks work into focused sessions (traditionally 25 minutes) separated by short breaks, with a longer break after every few sessions. This timer automates that cycle so you can just focus on the work.
Formula Explanation
After each focus session, the timer counts how many sessions you've completed in the current cycle. If that count reaches your configured "sessions per cycle" (default 4), the next break is a long break; otherwise it's a short break. After any break, the cycle returns to a focus session — repeating automatically with a sound cue at every transition.
Example Calculation
With the default settings (25 / 5 / 15, 4 sessions per cycle): Focus → Short Break → Focus → Short Break → Focus → Short Break → Focus → Long Break, then the cycle repeats.
How to Use
- Optionally adjust the focus, short break, and long break durations before starting.
- Click Start to begin your first focus session.
- Work until the timer ends — it automatically switches to a break and beeps.
- Use Skip to jump to the next phase early, or Reset to start the cycle over.
Benefits
- Automatically cycles between focus and break periods, including long breaks.
- Fully customizable session lengths for your own workflow.
- A sound cue means you don't need to keep watching the clock.
Use Cases
- Studying for exams in focused, distraction-free sprints.
- Structuring deep work blocks during the workday.
- Building a sustainable habit of regular breaks to avoid burnout.
What Your Result Means
The dots show your progress through the current cycle of focus sessions — once you complete the configured number, your next break is a longer one before the cycle resets.
Tips
- Use a real 25-minute focus session, at least at first — the technique relies on short, intense bursts of attention.
- Actually step away during breaks rather than continuing to work through them.
- Adjust the sessions-per-cycle setting if 4 focus sessions feels too many or too few before a longer break.
Common Mistakes
- Skipping breaks entirely, which defeats the purpose of preventing burnout.
- Setting unrealistically long focus sessions that are hard to sustain.
- Changing durations mid-session expecting the current countdown to update — durations only apply to the next matching phase.
FAQs
What is the Pomodoro Technique?
It's a time management method that breaks work into fixed focus intervals (traditionally 25 minutes), separated by short breaks, with a longer break after a set number of intervals.
Can I change the session lengths?
Yes, adjust the Focus, Short Break, Long Break, and Sessions per Cycle fields before starting — they're locked while a session is running to avoid disrupting an active countdown.
Does it make a sound when a session ends?
Yes, a short tone plays automatically whenever a focus session or break ends, using your browser's audio — no external app needed.
What happens after a long break?
The cycle resets and the next session is a fresh focus session, starting the count toward the next long break over again.
