A Pomodoro timer splits work into fixed focus sessions with short breaks between them and a longer break after every few sessions. The FindUtils Pomodoro Timer starts with the classic setup: 25 minutes of focus, a 5-minute short break, and a 15-minute long break after every 4 focus sessions. You can change all four numbers, and the timer moves you to the right break when a session ends. It runs in your browser with no sign-up.

This guide covers the controls, how a full cycle adds up, how to pick lengths for different kinds of work, and the mistakes that make the method stop working.

The Classic Cycle at a Glance

The technique was developed by Francesco Cirillo in the late 1980s and is named after the tomato-shaped kitchen timer he used as a student (pomodoro is Italian for tomato). The timer's defaults follow the common version of the method:

PhaseDefault lengthWhat happens next
Focus25 minutesShort break, or a long break after every 4th session
Short Break5 minutesFocus
Long Break15 minutesFocus, and a new set of 4 begins
Long Break After4 sessionsCan be set from 2 to 10

One full set with the defaults is 4 × 25 + 3 × 5 + 15 = 130 minutes, of which 100 minutes are focus time, about 77%. In practice that means:

Time you haveFocus sessions that fit (defaults)
2 hours4
4 hours7
6 hours11
8 hours15

These counts assume you start each session right after the previous break and stop once the next focus session would no longer fit.

How to Use the Pomodoro Timer

Step 1Pick One Task

Write down a single task before you press start. The method works because each session has one clear target, so "reply to the three client emails" works better than "work on email".

Step 2Start the Focus Session

The timer opens in Focus mode showing 25:00. Press the play button to start. The ring around the time fills as the session runs, and the label under the time reads Focus Time. Press the same button to pause.

Step 3Take the Break When It Ends

When the countdown reaches zero, a short sound plays (if sound is on) and the timer switches to Short Break, or to Long Break after every 4th completed session. The break does not start by itself: press play when you actually step away. That gives you a moment to note where you stopped.

Step 4Watch the Session Dots

Below the controls, one dot per session in the current set shows your progress. With the default setting there are 4 dots, and one fills each time a focus session runs to zero. After the 4th, the dots clear and the long break begins.

Step 5Reset When You Need To

  • The circular-arrow button resets the current phase to its full length and pauses it.
  • Reset All returns to Focus, sets the time back to the focus length, and clears the session count.
  • The three mode buttons at the top (Focus, Short Break, Long Break) jump straight to that phase, paused at its full length.

Changing the Lengths

Open Settings (the gear button) to change four values:

SettingDefaultRange in the settings fields
Focus Duration25 min1 to 60
Short Break5 min1 to 30
Long Break15 min1 to 60
Long Break After4 sessions2 to 10

A change to the phase you are in resets that countdown to the new length, so change settings between sessions, not halfway through one. The settings apply for your current visit; reloading the page brings back 25/5/15/4.

Setups for Different Kinds of Work

The 25-minute session is a convention, not a law. Descriptions of the original technique give a short break of 5 to 10 minutes and a long break of 20 to 30 minutes after four sessions; this timer defaults to a 15-minute long break, which you can raise. These setups all fit inside the settings ranges:

Research match24 / 6 / 6, after 4120 min80%Mirrors the "Pomodoro" condition in the study below

What the research says. A 2023 study in the British Journal of Educational Psychology (Biwer et al.) followed 87 university students through one real self-study day. One group took a 6-minute break after every 24 minutes, another a 3-minute break after every 12 minutes, and a third chose their own breaks. Students who chose their own breaks studied in longer stretches and reported more fatigue and distraction and less concentration and motivation before their breaks. Task completion and invested mental effort did not differ between the groups. Fixed breaks did not make students finish more, but they finished the same amount while feeling better. That matches how most people use a Pomodoro timer: as a guard against pushing on until they are drained.

Pairing the Timer With Other Tools

  • Plan the sessions. Sort the day's tasks in the Eisenhower Matrix and give the "important, not urgent" quadrant your first sessions.
  • Estimate reading. The Reading Time Estimator tells you roughly how long an article or chapter takes, so you can see how many sessions it needs.
  • Study in rounds. Build a deck in the Flashcard Maker and review one deck per focus session.
  • Hard deadlines. For a single fixed deadline, like a 45-minute exam practice, a plain Countdown Timer is simpler.
  • Measure, then plan. Use the Stopwatch to time how long a task really takes before deciding how many sessions to give it.

Common Mistakes to Avoid

Mistake 1: Skipping the Breaks

When a session goes well, it is tempting to skip the break. A few times is fine, but the break is half of the method. If you skip it every time, you are back to working until you are tired, which is the pattern the 2023 study linked to more fatigue.

Mistake 2: Checking Messages During the Break

A break spent in your inbox is not a rest. Stand up, get water, look at something far away. Leave messages for a session of their own.

Mistake 3: Counting Interrupted Sessions

In Cirillo's version, a pomodoro is indivisible: if you are interrupted and switch tasks, that session does not count, and you start a fresh one. Use the reset button rather than letting a broken session fill a dot.

Mistake 4: Changing the Length Mid-Session

Changing the focus length while a focus session runs restarts that countdown from the new length. Decide on lengths before you press start.

Mistake 5: Closing the Tab

The countdown and the session count live in the open page. Closing or reloading the tab resets both, so keep the timer in its own tab or window.

FAQ

How long is a Pomodoro?

The common length is 25 minutes of focus followed by a short break of about 5 minutes. After 4 sessions you take a longer break, 20 to 30 minutes in descriptions of the original technique. The FindUtils Pomodoro Timer uses 25, 5 and 15 minutes by default.

Can I change the 25-minute timer?

Yes. Open Settings and set the focus length anywhere from 1 to 60 minutes, the short break from 1 to 30, the long break from 1 to 60, and the number of sessions before a long break from 2 to 10.

Does the break start automatically?

No. When a focus session ends, a sound plays (if sound is on) and the timer switches to the next break, paused. Press play to start the break. The same happens when a break ends.

How many Pomodoros are in 8 hours?

With the default 25/5/15 setup and a long break after every 4 sessions, 15 focus sessions fit in 8 hours, which is 6 hours 15 minutes of focus. Lunch and meetings reduce that, so most people plan fewer.

Does the Pomodoro Technique actually work?

The evidence is limited but positive on how people feel. In a 2023 study of 87 students, those who took fixed breaks reported less fatigue and more concentration and motivation than those who chose their own breaks, while completing the same amount of work.

Is the Pomodoro Timer free?

Yes. The FindUtils Pomodoro Timer is free, needs no account, and runs in your browser.
