What is a pomodoro timer?
A pomodoro timer is a countdown clock used to run the pomodoro technique, the time-management method Francesco Cirillo described in the late 1980s. The method cuts work into a fixed interval — classically 25 minutes — followed by a short break of 5 minutes. Each work interval is called a pomodoro, after the tomato-shaped kitchen timer Cirillo used as a student. After four pomodoros you take a longer break of 15 to 30 minutes, then the cycle starts again.
The point is not the tomato, it is the constraint. A 25 minute timer turns a vague task into something small enough to begin, and because the finish line is defined you stop in a clean state instead of drifting into the next task. The breaks matter just as much: a 5 minute pause every half hour keeps attention fresh and gives your eyes a rest from the screen. Studies of short work-rest cycles keep finding the same thing — attention drifts after roughly 25 to 30 minutes of concentrated work, so a planned break costs less than the wandering it prevents.
This pomodoro timer online runs the whole loop in your browser. Set your intervals, press Start, and it counts down the focus block, beeps when the phase ends, switches to the right break, counts the focus sessions you complete and resets the cycle after the long break. Nothing is uploaded, no account is needed, and it keeps accurate time even if your browser throttles the tab.
How to use this pomodoro timer
- Leave the defaults for a classic cycle: 25 minutes of focus, a 5 minute short break, a 15 minute long break and a long break after every 4 focus sessions. Change any of them to suit your own rhythm.
- Press Start. The clock counts down the current phase in MM:SS and the progress bar fills as the phase runs.
- Press the same button again (Pause) to hold the remaining time; press Start to resume from exactly where you stopped.
- When the phase reaches 00:00 the timer beeps, the phase label flashes and it moves to the next phase — a break after focus, another focus block after a break.
- Watch the counters: Completed focus sessions totals the focus blocks you have finished, Focus sessions until the long break counts down to the longer break, and Total focus time this session adds up the focused minutes.
- Use Skip to jump to the next phase early, and Reset to clear the counters and go back to the start of a focus block.
- Tick Auto-start the next session if you want the breaks and the next focus block to begin on their own, and untick Beep when a phase ends if you need silence.
Worked example
Take the default settings: 25 minute focus, 5 minute short break, 15 minute long break, long break after every fourth focus session. One complete cycle is four focus blocks (4 × 25 = 100 minutes), three short breaks (3 × 5 = 15 minutes) and one long break (15 minutes) — 130 minutes, or 2 hours 10 minutes, of which 100 minutes (76.9%) is actual focus and 30 minutes is break. Within a single 25 plus 5 pair, focus takes 25 of 30 minutes, or 83.3%.
Start that cycle at 9:00 and the exact schedule is the table below: the first focus block ends at 9:25, the fourth ends at 10:55, the long break ends at 11:10, and at that moment the completed-session counter reads 4 before the cycle counter resets and the next block starts.
Leave the same settings running from 9:00 to 17:00 and the timer finishes 15 pomodoros and 375 minutes of focus — 6 hours 15 minutes, or 78.1% of the 480 minute window — because three full cycles take 390 minutes and the remaining 90 minutes fit exactly three more focus blocks and three short breaks, ending at 17:00 precisely. That is why a nominal eight-hour day usually contains six to seven hours of focus, not eight.
Who is this pomodoro timer for?
- Students and exam candidates: turn a chapter, a problem set or a set of flashcards into four 25 minute blocks and use the long break to walk away and reset before the next subject.
- Developers, writers and designers: split a large task into pomodoros, so a rewrite or a refactor has a start and an end and progress is counted in finished blocks instead of vague hours.
- People who struggle to start, including many with ADHD: a short interval with a visible finish line lowers the cost of beginning, and the session counter replaces the effort of tracking time internally.
- Anyone working or studying from home: with no office structure around you, the timer supplies the focus blocks and the breaks that a commute and a meeting calendar used to provide.
One classic pomodoro cycle
The table below is one full cycle at the default intervals, starting at 9:00. Cumulative elapsed minutes are measured from the moment the first focus block begins, and nothing is rounded.
| Session | Type | Duration | Cumulative elapsed | Clock time from 9:00 |
|---|---|---|---|---|
| 1 | Focus | 25 min | 25 min | 9:00 – 9:25 |
| 2 | Short break | 5 min | 30 min | 9:25 – 9:30 |
| 3 | Focus | 25 min | 55 min | 9:30 – 9:55 |
| 4 | Short break | 5 min | 60 min | 9:55 – 10:00 |
| 5 | Focus | 25 min | 85 min | 10:00 – 10:25 |
| 6 | Short break | 5 min | 90 min | 10:25 – 10:30 |
| 7 | Focus | 25 min | 115 min | 10:30 – 10:55 |
| 8 | Long break | 15 min | 130 min | 10:55 – 11:10 |
Figure 1 — one cycle of 130 minutes at 25 / 5 / 15 with a long break after the fourth focus block. Clock times assume the cycle starts at 9:00 with no pauses and no skipped phases.
Common use cases
- Deep work sessions: run four pomodoros back to back on one task, then take the long break before switching projects.
- Study blocks: one pomodoro per topic, with the session counter showing how much revision actually happened.
- Writing and editing: one pomodoro to draft, a short break, one pomodoro to revise — the fixed interval stops endless polishing.
- Chores and admin: clear an inbox or a filing pile in a single 25 minute block instead of letting it sprawl across the day.
- Pairing or co-working: everyone works the same intervals so breaks and check-ins land at the same minute.
Pro tips
- Write the task down before you start. A pomodoro is only as useful as the single task it is pointed at — decide it during the previous break, not when the clock hits zero.
- Protect the breaks. A 5 minute break spent scrolling feels longer than it is; stand up, look away from the screen or get water instead.
- Let a pomodoro finish. If an interruption arrives, note it and continue; if the task genuinely cannot wait, use Skip honestly rather than pausing the timer indefinitely.
- Track your real daily count. Finished sessions are a better measure of a working day than hours at the desk, and the counter here totals them as you go.
- Adjust the interval to the work. If 25 minutes constantly ends mid-thought, try 50 / 10; if you are new to the method, try 15 / 5 for a week first.
Frequently asked questions
What is the pomodoro technique?
The pomodoro technique is a time management method built on short, fixed work intervals. You work for 25 minutes on one task, take a 5 minute break, and repeat; after four focus intervals you take a longer break of 15 to 30 minutes. Each 25 minute interval is called a pomodoro, named after the tomato-shaped kitchen timer its inventor, Francesco Cirillo, used as a student in the late 1980s. The fixed end point makes a task easier to start, and the scheduled breaks keep attention steady across a long working session.
Why 25 minutes?
Twenty-five minutes is long enough to make real progress on a task and short enough that starting feels cheap. It also divides neatly into half-hour blocks: 25 minutes of work plus a 5 minute break is exactly 30 minutes, so four pomodoros fit neatly into a two-hour stretch of the day. The number is a convention rather than a rule — 50 minutes with a 10 minute break follows the same logic, and this timer lets you set any interval you prefer.
How long is a long break?
The classic long break is 15 to 30 minutes, taken after every fourth pomodoro. This timer defaults to 15 minutes and lets you change it. The long break exists so the short breaks stay genuinely short: instead of stretching every pause, you work through three quick 5 minute breaks and then step away properly to eat, walk or rest your eyes. If you plan a longer block of work, a 20 or 30 minute long break fits better.
How many pomodoros can I do in a day?
It depends on the length of your working window. Running the default 25 / 5 / 15 intervals continuously from 9:00 to 17:00 finishes 15 pomodoros and 375 minutes, or 6 hours 15 minutes, of focus, because one full cycle of four focus blocks plus the long break takes 130 minutes and three cycles plus three more blocks fill exactly 480 minutes. Most people plan 8 to 12 pomodoros and treat the rest of the day as meetings, email and admin. Counting pomodoros instead of hours is the point: you plan the work you can actually focus on.
Does the pomodoro technique work for studying?
Yes, and studying is one of its most common uses. Students use a 25 minute timer to work through a problem set, a textbook chapter or a set of flashcards, then take 5 minutes off. The break is short enough that restarting is easy, which helps with subjects you tend to avoid. A typical plan is four pomodoros per subject, with the long break used for a walk instead of a screen.
Does a pomodoro timer help with ADHD?
Many people with ADHD find it useful for one specific reason: the interval is short and the end is visible, so a task stops looking endless. A visible countdown and a session counter also replace the effort of tracking time internally, which is exactly what makes long open-ended work hard to start. It is not a treatment and it does not suit everyone — if a 25 minute block feels too long, begin with 15 minutes and extend it once the habit sticks.
Does it work while working from home?
Yes, and it is arguably more useful at home, where the day no longer segments itself into commutes, meetings and office chatter. The timer supplies the structure an office used to provide: a defined focus block, a defined break and a counter that shows how much real work you finished. Because it is an ordinary browser tab, it stays visible next to your editor, notes or spreadsheet.
Can I change the intervals?
Yes. Set the work length, the short break, the long break and the number of focus sessions before a long break to anything you like, and the schedule adapts immediately. A change applies to the current phase if it has not started yet, and to the next phase otherwise, so you never lose a countdown that is already running. Popular variations are 50 / 10, 45 / 15 and 90 / 20.
Does the timer run in the background?
Yes. The countdown is anchored to the system clock instead of counting refreshes, so if your browser throttles a background tab the remaining time and the session counter are still exact when you return. Sound can be delayed when a tab is hidden, because some browsers throttle timers to about one wake-up per minute; the beep then plays slightly late rather than not at all. Keep the tab visible if the alarm matters to you.
Is this pomodoro timer free?
Yes. It is free, there is no sign-up, no download and no limit on how many sessions you run. The timer runs entirely in your browser and nothing you type or time is sent anywhere.
Do I need an account?
No account, no email address and no login. Open the page and press Start. Your intervals and your progress through the current cycle are held in this tab's session storage so that a refresh does not throw away your session; nothing is stored on a server and closing the tab clears it.
What is the difference between a pomodoro timer and a countdown timer?
A countdown timer counts down once and stops. A pomodoro timer runs a repeating cycle: it counts down a focus block, beeps, switches to a break, beeps again, counts the focus sessions you have finished and takes a longer break after every fourth one. Use a plain countdown timer for a single interval such as a cooking or exam timer, and a pomodoro timer when you want the whole work-and-break pattern handled for you.
