How the Pomodoro Technique works
The idea is almost embarrassingly simple — and that is why it works. Pick one task, set the timer for 25 minutes, and work on nothing else until it rings. Then take a real 5-minute break: stand up, stretch, look out of the window, drink water. After four focus blocks, take a longer 15–30 minute break. The fixed sprint removes the hardest part of any big task — starting — because "just 25 minutes" never feels overwhelming.
This timer switches modes for you automatically: focus → short break → focus … and after your 4th focus session it offers the long break. Your completed sessions light up as dots under the clock, and today's totals stay on this page.
Pomodoro variations that actually get used
| Style | Focus | Breaks | Best for |
|---|---|---|---|
| Classic | 25 min | 5 / 15 min | Studying, admin, email batches |
| Deep work | 50 min | 10 / 20 min | Coding, writing, design |
| Sprint | 15 min | 3 / 10 min | Short attention spans, tidying, warm-ups |
| Ultradian 90/20 | 90 min | 20 / 30 min | Long writing sessions, exam prep marathons |
Tap any preset above the timer — or set your own lengths. There is no "correct" interval, only the one you will actually repeat tomorrow.
Make each pomodoro count — 5 rules
- One task, written down. Vague goals ("study physics") lose to concrete ones ("solve 10 friction problems"). Use the task list above.
- Phone face-down, notifications off. A single glance costs you far more than the 3 seconds it takes.
- Breaks are breaks. No "quick check of messages" — your brain recovers when it fully switches off.
- Interruptions go on paper. If something pops into your head mid-focus, jot it down and return to it in the break.
- Track, don't judge. 3 honest pomodoros beat 8 distracted ones. Watch your daily minutes grow instead of chasing a number.
Frequently asked questions
What is the Pomodoro Technique?
A time-management method created by Francesco Cirillo in the late 1980s: work in focused 25-minute blocks, take a 5-minute break, and after four blocks take a longer 15–30 minute break. The short fixed sprint makes hard tasks easier to start, and the breaks protect your attention across a long day.
Does the timer keep running if I switch tabs?
Yes. It calculates from a saved end-time rather than counting ticks, so it stays accurate in background tabs — and the countdown shows in your browser tab title so you can glance at it from another window.
What intervals should I use for studying vs deep work?
Start with classic 25/5/15. For deep work like coding or writing, try 50/10; for short attention spans 15/3; for long exam-prep sessions the 90/20 ultradian rhythm. One-tap presets for all four are above the timer.
Where are my tasks and stats saved?
Only in your own browser (localStorage) — tasks, custom intervals and today's stats. Nothing is uploaded anywhere and no account is needed. Clearing browser data will reset them.
Can I use this as a plain countdown or stopwatch?
Yes — switch to the Countdown tab for exams, cooking or workouts (set any minutes), or the Stopwatch tab to time anything upwards with lap-free simplicity.
