Idle
Completed Pomodoros: 0
Timer Settings
Long break after this many work sessions
How to Use
- Configure the timer
Set your preferred focus and break durations. The defaults are 25 minutes for focus and 5 minutes for breaks.
- Start the session
Click Start to begin your focus session. The break timer starts automatically when the focus session ends.
- Repeat the cycle
Alternate between focus and break sessions. Take a longer break after completing four cycles.
What is the Pomodoro Technique?
The Pomodoro Technique is a time-management method devised by Italian developer Francesco Cirillo in the late 1980s. The name comes from the tomato-shaped (pomodoro in Italian) kitchen timer he used as a university student.
The core idea is to break work into short focused units called ‘pomodoros’. One pomodoro is 25 minutes of focus + a 5-minute break; after four repetitions you finish the set with a 15–30 minute long break.
Why it works
- Beats procrastination — the small promise of ‘just 25 minutes’ lowers the psychological barrier to starting.
- Prevents burnout — regular breaks interrupt the build-up of mental fatigue.
- Quantitative tracking — counting completed pomodoros tells you how many a task takes, sharpening your scheduling.
Calculation Formula
The duration of each phase (in seconds) and the rule for the next phase are calculated as follows.
Phase time (sec) = set minutes × 60Next phase = (completed pomodoros mod long-break cycle == 0) ? long break : short break
Example (defaults: work 25 min, short break 5 min, long break 15 min, cycle 4):
- One work session = 25 × 60 = 1,500 sec
- After the 1st–3rd work sessions → 1·2·3 mod 4 ≠ 0, so a short break (5 min)
- After the 4th work session → 4 mod 4 = 0, so a long break (15 min)
Total time per set (4 pomodoros) = work 25×4 + short break 5×3 + long break 15 = 130 minutes.
