What the Pomodoro Technique is
The Pomodoro Technique is a time-management method devised by Francesco Cirillo in the late 1980s. You pick one task, work on it with full attention for25 minutes, then take a 5-minute break, and repeat. The name comes from the tomato-shaped kitchen timer Cirillo used; "pomodoro" is Italian for tomato. The number 25 matters less than the structure behind it. You cut the day into small boxes of time, commit to one thing inside each box, and get a clear end point to aim for. A visible finish line makes it easier to begin, and each completed box is a small checkpoint that shows how far a piece of work has really come.
How this timer behaves
- The focus period counts down from the number of minutes you set (25 by default). When it reaches zero, the completed count goes up by one, the minutes are added to your focus total, and a short beep plays.
- The break period starts straight away with your break length (5 minutes by default). When it ends, the next focus period begins automatically and the beep plays again.
- Pause stops the clock and keeps the remaining time. Start continues from where you left off. Reset stops everything, sets the counters back to zero and returns to a fresh focus period.
- The two length fields are locked while the clock is running. Pause or reset to change them. If you change a length before starting, the display updates immediately.
The tool does not have a separate long-break setting. If you like a longer rest after every fourth round, press Pause as soon as the break after the fourth focus period begins, take as long as you need, and press Start when you are ready; the paused break then finishes its remaining time before the next focus period starts. Values outside the allowed range (focus 1 to 120, break 1 to 60) are corrected to the nearest allowed value and a short message tells you so.
Is the clock accurate in a background tab?
Browsers often slow down timers in tabs you cannot see, so a timer that simply subtracts one second per tick can run late. This one stores the moment the current period should end and, on every check, works out the remaining time from the real clock. When you come back to the tab, the display is correct. The time left is also written into the tab title, such as "12:34 - Focusing", so you can read it without switching tabs. Be aware that a hidden tab may check the clock less often, so the beep can arrive a little late there. If the computer goes to sleep, the browser is paused too; when it wakes, the period that ended during sleep is finished at the next check and counts as completed.
Sound and notifications
This page signals the end of a period with a short tone generated in your browser. Many browsers refuse to play audio until you have interacted with the page, which is why the Start button matters: once you have clicked it, the tone can play. If you hear nothing, check the device volume and whether the tab is muted. This tool does not use the browser notification system, so it never asks for notification permission and cannot pop up a message when the tab is hidden. The tab title is the other cue, and the tone is the only alert.
Schedules for common settings
The table shows four rounds of each setting. "Until the last focus ends" leaves out the break that follows the final focus period; "including final break" counts it, because this timer starts a break after every focus period.
| Setting | Focus / break | Focus total | Until the last focus ends | Including final break |
|---|---|---|---|---|
| Classic | 25 / 5 min | 1 h 40 min | 1 h 55 min | 2 h |
| Deep focus | 50 / 10 min | 3 h 20 min | 3 h 50 min | 4 h |
| Gentle start | 15 / 3 min | 1 h | 1 h 9 min | 1 h 12 min |
With the classic setting, four rounds give 100 minutes of focus and three breaks of 5 minutes, so the last focus period ends 115 minutes after you press Start, or 120 minutes if you include the break that follows. When you put pomodoros in a calendar, block the breaks as well, not just the focus minutes; otherwise the plan runs late.
How many rounds fit in a day?
This table assumes the classic 25/5 setting and no extra time for meetings or interruptions.
| Rounds | Focus time | Until the last focus ends | Including final break |
|---|---|---|---|
| 4 | 1 h 40 min | 1 h 55 min | 2 h |
| 6 | 2 h 30 min | 2 h 55 min | 3 h |
| 8 | 3 h 20 min | 3 h 55 min | 4 h |
| 12 | 5 h | 5 h 55 min | 6 h |
Eight rounds are 200 minutes, a little over three hours, of real focus, and the whole stretch lasts close to four hours. A day with many meetings, messages and errands may hold far fewer. For the first week, aim for four to six rounds and write down how many you actually finish. That personal average is a better planning number than any figure from the table.
Getting more out of each round
- Write the goal first. One line such as "draft the intro of the report" is enough. It should fit in a single round; split larger jobs into several.
- Park distractions on paper. When a stray thought or a "quick search" tempts you, jot it on a sheet and go back. Leaking into email and browsing is the most common way a round fails.
- Spend breaks away from the screen. Stand, stretch, drink water, look out of a window. Opening social media in a five-minute break makes it hard to return.
- Compare estimates with reality. Note "guessed 3 rounds, took 5" next to each task. After a couple of weeks your estimates get noticeably better.
- Decide what counts as a finished round. If an urgent interruption cuts a round in half, press Reset and start again rather than counting it as complete; your tally stays honest that way.
A morning example
Start at 9:00 with the classic setting and the first four rounds run like this: focus 9:00 to 9:25, break to 9:30; focus 9:30 to 9:55, break to 10:00; focus 10:00 to 10:25, break to 10:30; focus 10:30 to 10:55. That is 100 minutes of work in 115 minutes on the clock. If you want a longer rest at this point, pause when the break after the fourth focus begins and resume once you are ready. A meeting in the middle should be planned as a gap of at least one round's length on each side so that it does not push the rest of the morning off schedule.
On days when starting feels hard, promise yourself just one round and drop the focus time to 15 minutes. Small successes make it easier to move up to 25 and later 50. Because the counters on this page disappear when you reload, keep a tally on paper if you want to see the total for the day.
When it is not a good fit, and common misconceptions
- 25 minutes is a convention, not a law. Work such as programming or writing can take a while to warm up, so some people prefer 50 minutes; on a scattered day 15 may be better. There is no single scientifically proven ideal length, so try a few settings over some weeks and keep the one that suits you.
- It can interrupt deep flow. If you are already deep in a task when the beep sounds, you lose something. Finish the thought, then take the break, or use the timer only to keep a record of time.
- Reactive jobs. If your day is mostly answering people, fixed 25-minute blocks are unrealistic and a looser plan of time blocks may serve you better.
- Skipping breaks. Pushing on without rests tends to lower the quality of later rounds, so treat breaks as part of the plan.
- It is not a health tool. The timer helps you organize work; it does not measure attention and is not medical or psychological advice.
Privacy and what is stored
Everything runs in your browser. The timer does not save your settings, rounds or focus total anywhere, neither in cookies nor in local storage, and none of it is sent to a server. Closing or reloading the tab resets the timer and counters to their defaults, and the tool only runs while the tab is open.
Frequently Asked Questions
Can I change the focus and break lengths?
Yes. Use the two fields under the timer. They lock while the clock is running; pause or reset to edit them. If the current period has not started yet, the display updates as soon as you change a value.
I can't hear the alert sound.
Browsers often block audio until you have interacted with the page, so press Start first. Also check the device volume and that the tab is not muted. The tab title still shows the time left even when the sound is silent.
Does it send desktop notifications?
No. This version only plays a tone and updates the tab title, so it never asks for notification permission. Keep the tab audible if you rely on the alert.
Will the time be wrong if I switch to another tab?
No. The remaining time is calculated from the real clock against a stored end time, so errors do not pile up while the tab is hidden. The beep itself may come slightly later in a hidden tab.
Is my progress saved?
No. Nothing is stored and nothing is uploaded. The completed count and the focus total return to zero when you reload or close the page, so jot down any totals you want to keep.
