What is the Pomodoro Technique?
The Pomodoro Technique is a proven time-management method: work in focused 25-minute sprints separated by short breaks. It fights procrastination, reduces burnout, and makes big tasks feel manageable. This free Pomodoro timer runs entirely in your browser — no app to install.
How to use this timer
Pick Focus and hit start. Work until the timer rings, then take a Short Break. After four focus sessions, reward yourself with a Long Break. The counters track your completed sessions and total focused minutes for the day.
Why it works
Short, time-boxed sprints create urgency and protect your attention from distraction. Pair this timer with a good task manager — our project management software guide can help you choose one.
Where the Pomodoro Technique came from, and what it is actually for
The technique was developed by Francesco Cirillo in the late 1980s while he was a university student, named after the tomato-shaped kitchen timer he used. The structure is deliberately simple: pick one task, work on it for 25 minutes without interruption, take a 5-minute break, and after four such cycles take a longer break of 15 to 30 minutes.
The part most people miss is that the timer is not primarily a productivity device. It is a measuring instrument. The original method asks you to record how many pomodoros a task actually took, so that over a few weeks you build a realistic picture of your own throughput. Most people badly underestimate how long work takes; counting completed intervals is the cheapest available correction to that.
Why the interruption rule matters more than the 25 minutes
Task-switching carries a real cost. Attention does not transfer cleanly between tasks: a residue of the previous one persists and degrades performance on the new one, an effect documented in the attention research literature as attention residue. Every time you break a work interval to check a message, you pay that cost twice — once switching out and once switching back.
The rule in the original method is that if an interruption arrives, you write it down and deal with it in the break. If the interval genuinely cannot be saved, you void the pomodoro and start fresh. That sounds severe, and it is the point: it makes the cost of interruption visible instead of invisible.
25 minutes is a starting point, not a law
The interval length is arbitrary and Cirillo chose it for a beginner. If you are doing work with a long warm-up — debugging, writing, complex analysis — 25 minutes can cut you off just as you settle in, and 45 or 50 minutes with a 10-minute break often works better. If you are struggling to start at all, shorter intervals of 10 or 15 minutes lower the barrier to beginning, which is usually the real problem.
What should not change is that the break is a real break. A break spent scrolling is not recovery; it is a different task. Stand up, look at something further than arm distance away, get water.
When the technique does not fit
It suits work that can be sliced into intervals and does not suit work that cannot. Meetings, live support, on-call rotations and anything genuinely reactive will break every interval you start, and forcing the method there produces frustration rather than focus. Use it for the deep-work blocks in your day and leave the reactive parts alone.
Frequently asked questions
Does this timer keep running if I switch tabs?
Yes. The countdown is based on elapsed clock time rather than a tab-active counter, so switching tabs or minimising the window does not pause or slow it. Browsers throttle background tabs, which breaks naive timers; this one accounts for that by measuring against the real time.
Do I need to allow notifications?
No, the timer works without them. Granting notification permission simply means you get an alert when an interval ends even if the tab is not in front of you, which is the whole point of not having to watch a clock. Permission is requested by your browser, not by us, and you can revoke it at any time in site settings.
Is my session data stored anywhere?
Nothing is sent to a server. Session counts live in the page while it is open and are not tied to any account, profile or identifier. Refreshing or closing the tab clears them.
What should I do if I get interrupted mid-interval?
Write the interruption down and return to it in the break. That single habit is where most of the benefit lives, because it converts a context switch into a queued item. If the interruption is genuinely urgent, stop the interval and restart it afterwards rather than trying to salvage a broken one.
How many pomodoros should I aim for in a day?
Fewer than people expect. Eight to twelve intervals of genuinely uninterrupted work is a strong day for most knowledge work, and chasing a higher number usually means the intervals are not really uninterrupted. Track what you actually complete for two weeks before setting any target. If you are planning workload across a team, our meeting cost calculator makes the other half of the equation visible.
