A Pomodoro timer breaks your work into fixed focus sessions separated by short breaks, so you concentrate on one task at a time instead of working in a long, unstructured stretch. The timer below runs entirely in your browser. You set the work and break lengths, press Start, and it counts down each session, switches to a break automatically, and keeps a count of the focus sessions you finish.
What the Pomodoro Technique Is
The Pomodoro Technique is a time management method that divides work into intervals, traditionally 25 minutes long, separated by short breaks. Each interval is called a Pomodoro, named after the tomato shaped kitchen timer its inventor used. You commit to a single task for the length of one Pomodoro and do nothing else until the timer ends. The method turns a vague block of work into a series of small, countable units, which makes progress visible and keeps your attention on one thing at a time.
How to Use It
- Set the work minutes, short break, and long break to the lengths you want, or leave the defaults of 25, 5, and 15.
- Pick one task to work on for the next session.
- Press Start. The timer counts down the work session and shows the minutes and seconds left.
- Work on that task only until the timer reaches zero, then take the break it switches to.
- Repeat. After four work sessions the timer gives you a long break instead of a short one.
- Use Pause to stop the clock and Reset to clear the count and return to a fresh work session.
The Work and Break Cycle
The standard cycle alternates focus and rest in a fixed pattern. Each work session is followed by a short break, and the long break arrives only after a set of four work sessions, giving you a longer rest before the next round begins.
Why Timeboxing Helps Focus
Timeboxing means assigning a fixed amount of time to a task in advance. A running countdown creates a mild sense of urgency that pushes you to start and to stay on the task rather than drifting to email or messages. Because the session is short and has a clear end, the cost of starting feels low, which makes it easier to begin work you have been putting off. The breaks matter just as much: regular pauses keep attention from degrading over a long stretch, so the focus you bring to each session stays high.
Customizing the Intervals
The 25/5 split is a starting point, not a rule. Some tasks need a longer run to reach depth, so a 50 minute work session with a 10 minute break can suit deep work better. Other tasks, or low energy days, work better with shorter sessions. Set the work, short break, and long break fields to whatever length keeps you productive without strain. The point of the method is the rhythm of focused work and deliberate rest, and the exact numbers are yours to adjust.
It Runs in Your Browser
This timer runs entirely on your device. There is no account, no app to install, and nothing you enter is sent to a server. The countdown, the phase switching, and the session count are all handled locally in your browser, so the tool keeps working even if you lose your connection. Keep the tab open while you work and the timer counts down each session for you.
When to Use It
A Pomodoro timer suits any task that benefits from sustained attention: studying, writing, coding, reviewing, or clearing a backlog of focused work. It is most useful when a task feels large or when distractions are pulling at you, because the short session gives you a small, achievable target and a clear point to rest. It is less suited to work that must run uninterrupted, such as a meeting or a continuous process, where a break in the middle would not help.
Last Thoughts on Using a Pomodoro Timer
The hard part of focused work is rarely the work itself. It is starting, and then staying on the task long enough to make progress. A Pomodoro timer solves both by shrinking the commitment to a single short session and giving you a built in point to rest. The rhythm of focus and break is what carries you through a long day without the attention drain of one unbroken stretch.

Key Takeaways:
- The Pomodoro Technique splits work into focus sessions, traditionally 25 minutes, each followed by a short break.
- A long break of about 15 minutes follows every fourth work session, and this timer tracks that automatically.
- Fixed sessions create urgency and make progress countable; the breaks keep attention from degrading.
- The 25/5 split is a default, not a rule. Adjust the work and break lengths to fit the task and your energy.
- The timer runs entirely in your browser, with no account, no install, and nothing sent to a server.
- Use it for studying, writing, coding, or any task that benefits from sustained, single task focus.
Frequently Asked Questions (FAQs)
How long is a Pomodoro?
A standard Pomodoro is 25 minutes of focused work followed by a 5 minute break. The length is a convention rather than a fixed rule, and you can set this timer to any work and break lengths that suit your task and attention span.
When does the long break happen?
The long break comes after every fourth completed work session. This timer counts your finished work sessions and switches to a long break instead of a short one when you reach a multiple of four, then returns to the normal cycle.
Can I change the work and break lengths?
Yes. Set the work minutes, short break, and long break fields to any value before you start. A 50/10 split works well for deep work, while shorter sessions can help on low energy days. The rhythm of focus and rest matters more than the exact numbers.
Does the timer keep running if I switch tabs?
The timer runs in your browser, so it continues counting while the page stays open. Some browsers slow background tabs, so it is best to keep the timer tab visible during a session if you want the most accurate countdown.
What does the Pause button do?
Pause stops the countdown without losing your progress, so you can step away and pick up where you left off. Reset clears the session count and returns the timer to a fresh work session if you want to start over.
Is my data sent anywhere?
No. The timer runs entirely on your device. The countdown, the phase switching, and the session count are handled locally in your browser, and nothing you enter is transmitted, logged, or stored on any server.
