Pomodoro Timer
25:00
How to use this Pomodoro timer
Click Start to begin a 25-minute focus session. When it ends, take a 5-minute break (click "Short break 5"). Every fourth Pomodoro, take a longer 15-minute break instead. Repeat through your work day.
The timer runs entirely in your browser — close the tab and the count resets, so leave it open in a pinned tab while you work.
What is the Pomodoro Technique?
The Pomodoro Technique is a time-management method developed by Francesco Cirillo in the late 1980s. Cirillo named it after the tomato-shaped (pomodoro in Italian) kitchen timer he used as a university student. The method has since become one of the most widely-adopted productivity systems in writing, software development, and study skills.
The core idea is simple: work in fixed, undivided 25-minute intervals, separated by short breaks. The fixed interval forces a single-task focus, the break enforces recovery, and the repetition builds rhythm.
How the Pomodoro Technique works (5 steps)
- Choose one task. Not a list — one task. Write it on paper.
- Set the timer for 25 minutes. The interval is non-negotiable.
- Work the task with full focus. No email, no Slack, no quick checks. If something pops into your head, jot it on the paper and return to the task.
- When the timer rings, mark a Pomodoro. Take a 5-minute break — stand up, drink water, look out the window. Don't open another screen.
- Every four Pomodoros, take a 15–30 minute break. This is when you process email, switch context, or eat.
Why 25/5? The science behind the intervals
The 25-minute interval predates modern attention research, but the choice has held up. Sustained focus on a cognitively demanding task degrades sharply after about 20–30 minutes for most adults. Beyond that point you're not "still working" — you're rereading the same paragraph, checking notifications, drifting.
The 5-minute break exploits the brain's diffuse mode of thinking. When you stop forcing focused attention, your default-mode network activates and consolidates what you just learned. This is why insights often arrive on a walk, in the shower, or right as you sit back down. Pomodoro builds those moments into the work day.
The longer 15–30 minute break every four Pomodoros (roughly two hours) aligns with the ultradian rhythm identified by sleep researcher Nathan Kleitman: a roughly 90–120 minute cycle of high and low alertness. Longer breaks at this cadence let your nervous system fully reset before the next high-focus block.
Pomodoro for writers
Pomodoro is particularly well-suited to writing because it solves the two biggest writing problems at once:
- Starting — committing to 25 minutes is easier than committing to "writing today".
- Editing while drafting — the break boundary forces you to push through to the end of a section before reviewing.
A typical writing day with Pomodoro:
- Pomodoro 1–2: outline + first draft of one section.
- Long break: review what you wrote, jot notes.
- Pomodoro 3–4: continue drafting.
- Long break: lunch.
- Pomodoro 5–6: edit the morning's draft.
- Pomodoro 7: research / future-section notes.
- Pomodoro 8: shutdown — clear desk, log progress.
That's eight Pomodoros — about 4 focused hours of writing — which is a lot more than most writers actually produce in a "full day".
Pomodoro variations
| Variation | Work | Break | Best for |
|---|---|---|---|
| Classic Pomodoro | 25 min | 5 min | Default — most knowledge work |
| 50 / 10 | 50 min | 10 min | Deep work that needs ramp-up |
| 90-minute ultradian | 90 min | 20 min | Programmers, designers, mathematicians |
| Short Pomodoro | 15 min | 3 min | Avoidance-prone tasks; getting started |
| Flowtime | Until natural stopping point | 1/5 of work time | Tasks where flow is more important than rhythm |
Common Pomodoro mistakes
- Skipping the break. The break is not optional. Skipping breaks turns Pomodoro into a stopwatch, which is just timed work, which doesn't help.
- Filling the break with screens. Doom-scrolling for 5 minutes is not recovery — your eyes and prefrontal cortex are still loaded.
- Pausing the timer. If something interrupts you, end the Pomodoro and restart fresh. Don't pause-and-resume.
- Stacking too many Pomodoros. Eight in a day is hard; ten is unsustainable. Quality over quantity.
- Multi-tasking inside the Pomodoro. One task per Pomodoro is the whole point.

Frequently asked questions
Why 25 minutes specifically?
Cirillo originally tried 30 minutes and 45, but found 25 the longest interval at which his attention reliably stayed sharp. Modern research on sustained-attention tasks puts the breakpoint between 20 and 30 minutes for most adults, which is why 25 is now the standard.
What if a task takes more than one Pomodoro?
That's the normal case. Most real work takes 2–6 Pomodoros. Track Pomodoros per task as a planning metric — over time you'll learn that "writing a 1,500-word post" is a 4-Pomodoro task for you, and you'll plan accordingly.
Can I check email between Pomodoros?
During a long break (every 4 Pomodoros), yes. During a short 5-minute break, no — opening email loads context that takes minutes to discharge before you can refocus.
Is Pomodoro suitable for creative work?
Yes, with one caveat: if you're in deep flow at the 25-minute mark, finish the thought before stopping. The technique is a default rhythm, not a religion.
Does Pomodoro work for studying?
Especially well. Active recall and spaced practice both benefit from the work/break structure, and the 5-minute break is exactly the right length for spaced rehearsal of what you just learned.
What's the best app or timer?
This page works as a permanent pinned tab. If you want native notifications and longer-term tracking, Be Focused (Mac/iOS), Pomofocus.io, and Forest (mobile) are all popular. The technique itself is more important than the tool.
Does the timer make a sound when it ends?
Yes — the page plays a soft chime when the work or break period ends, even if the tab is in the background. Browser tab notifications must be allowed for this to work.
