Pomodoro Timer
Stay focused with the Pomodoro Technique. Work in 25-minute intervals with short breaks to maximize productivity and learning.
- Work for 25 minutes (one "pomodoro")
- Take a 5-minute short break
- After 4 pomodoros, take a 15-minute long break
- Repeat!
The Pomodoro Timer helps you study and work more effectively using the proven Pomodoro Technique. Work in focused 25-minute intervals (called 'pomodoros') followed by 5-minute breaks, with a longer 15-minute break after every fourth one. This method combats procrastination, reduces mental fatigue, and helps maintain high concentration levels. When a session runs out the timer switches to the next phase on its own and waits, so you decide when to start the break rather than being rushed into it.
What the three timer modes do
The timer has three modes, and you switch between them with the tabs above the clock. Focus runs for 25 minutes, Short Break for 5, and Long Break for 15. Those are the standard Pomodoro Technique intervals, and they are fixed here, so there is nothing to set up before you start. Press Start, and the countdown begins from 25:00.
Each mode has its own colour so you can tell at a glance what you are meant to be doing: red for focus, green for the short break, blue for the long one. A progress bar under the clock fills up as the session runs, which is useful if you have the tab open on a second screen and only glance at it now and then.
Start becomes Pause once the countdown is running, so you can stop for a knock at the door and pick up where you left off. Reset takes the current mode back to its full length without touching your session count. Switching tabs mid-session also resets the clock to that mode's full time, so if you are halfway through a focus block, use Pause rather than clicking another tab.
How the 25-minute cycle runs itself
When a focus session hits zero, the timer counts it as one completed pomodoro and switches modes for you. After the first, second and third focus blocks it moves to the 5-minute short break. After the fourth it gives you the 15-minute long break instead, then starts the count again. When a break ends, it switches back to Focus. You still press Start each time, so a finished break will not drag you into work before you are ready.
The tally under the controls shows how many focus sessions you have finished in this sitting. It lives in the page, not in an account, so closing the tab or reloading clears it back to zero. For most people that is the point: the number is a nudge for the afternoon, not a permanent record.
The countdown reads real clock time rather than counting ticks, so it keeps correct time even when the browser throttles a background tab. You can open this study timer in one tab, work in another, and come back to find the right number of minutes left rather than a clock that quietly fell behind.
Using a focus timer with children and teenagers
Twenty-five minutes is a long stretch for a younger child. For primary-age homework, many parents run one focus block and stop there, or treat it as a ceiling rather than a target: if the maths is done in twelve minutes, the break is earned. From around Year 7 or 8 upwards, two or three blocks in an evening is a realistic amount of revision, and the set of four followed by a long break tends to be more useful in exam season than during term-time homework.
The break matters as much as the focus block, and it works best away from a screen. Getting a drink, stretching, walking to the end of the garden and back all reset attention better than five minutes of scrolling, which tends to run long and leave you more tired than when you sat down. Agreeing what the break looks like before the first session starts saves an argument at 25:00.
In a classroom, the same intervals work for silent reading, independent writing or exam practice, projected where everyone can see the clock. Children who struggle to settle often find the visible progress bar helpful, because it makes the end of the task concrete: you are not working until the teacher says stop, you are working until the bar fills.
Where the technique came from, and when to ignore it
The Pomodoro Technique was developed by Francesco Cirillo in the late 1980s, named after the tomato-shaped kitchen timer he used as a student. Hence the tomato timer nickname you will still see attached to it. The core idea has not changed: a short, protected block of single-tasking, a deliberate break, and a count of how many blocks you got through.
It suits work that is easy to avoid and easy to fragment, which is why it caught on for essay writing, revision, marking and admin. It is a poor fit for anything where being interrupted costs more than the break is worth, and it can be counterproductive if you are genuinely absorbed in something. If 25:00 arrives and you are in the middle of a sentence, finishing the sentence is better practice than obeying the clock.
The productivity timer is free, runs in the browser, and needs no sign-up or download. Nothing you do here is sent anywhere, so it works on a school laptop or a shared family computer without leaving anything behind.
Frequently Asked Questions
What is a pomodoro timer?
It is a timer that splits work into fixed 25-minute focus blocks separated by short breaks, with a longer break after every fourth block. The blocks are called pomodoros, after the tomato-shaped kitchen timer the method was named for.
Can I change the 25-minute length?
Not on this page. The intervals are fixed at 25, 5 and 15 minutes so there is nothing to configure before you start. If you want a shorter block for a younger child, use Pause and stop early rather than waiting for zero.
Does the timer keep running if I switch tabs?
Yes. The countdown is based on the actual clock rather than on the browser ticking along, so it stays accurate in a background tab. You will need to keep the page open, though, since closing it loses the session.
Why did it jump to a 15-minute break?
That is the long break, and it arrives automatically after your fourth completed focus session. The three before it each get the 5-minute short break.
Does my completed pomodoro count get saved?
No. The tally resets to zero when you reload or close the page. It is there to show progress within one sitting, not to keep a history.
Is this online pomodoro timer free?
Yes, and there is no account, no download and no limit on how many sessions you run. It works in any modern browser on a phone, tablet or laptop.
What age is the Pomodoro Technique suitable for?
Most children can manage a 25-minute block from around age eleven or twelve, and many teenagers use it for revision. Below that, shorter stretches usually work better, so treat the focus block as a maximum rather than a target.
