How long is a Pomodoro?

Traditionally 25 minutes of focused work followed by a 5-minute break. You can change both in the settings fields.

What is a long break?

After a set number of focus sessions, usually four, you take a longer break of 15 to 30 minutes to recover.

Will the timer keep running in a background tab?

Yes. It checks the real clock, so it stays accurate. The remaining time also appears in the tab title.

Why did I not hear the beep?

Some browsers mute audio until you interact with the page or if the device is on silent. Press Start once and check your volume.

Does it save my settings or sessions?

No. Nothing is stored, so settings reset when you reload the page.

Pomodoro Timer – 25/5 Focus Timer with Breaks

Start the timer, focus until the beep, then take the break. The countdown also shows in the browser tab, so you can switch windows.

The Pomodoro Technique in brief

The Pomodoro Technique was developed by Francesco Cirillo in the late 1980s. You pick a task, work on it with full attention for a fixed block, traditionally 25 minutes, then take a short break of about 5 minutes. After four focus blocks you take a longer break of 15 to 30 minutes. The name comes from the tomato-shaped kitchen timer Cirillo used as a student. The idea is simple: time-boxing makes starting easier and regular breaks reduce fatigue.

How to use this timer

Write down the one task you will work on. Remove distractions such as notifications.
Press Start. The timer shows the time remaining for the current phase and updates the page title, so you can see it from another tab.
When the phase ends you hear a short beep and the next phase begins automatically: a short break, then another focus block, and a long break after every fourth block (adjustable).
Use Pause to stop temporarily, Skip phase to move on early and Reset to go back to the first focus block.

Adjusting the lengths

25 and 5 minutes are only defaults. Some people prefer 50 minutes of focus and 10 of rest for deep work, others use 15-minute blocks to get started on tasks they are avoiding. Change the numbers and the timer loads the new lengths when it is paused or reset. Values from 1 to 600 minutes are accepted. If you type something invalid, the tool falls back to the default.

Making it work in practice

If you are interrupted, note the interruption and return to the block, or restart it. Cirillo's rule is that a block is indivisible.
Use breaks to stand up, stretch or drink water, not to check social media, which makes it harder to return to focus.
Count completed blocks at the end of the day to see how much focused time you really get.

Technical notes

The countdown is based on the clock rather than on counting ticks, so it stays accurate if your browser throttles background tabs. The beep is generated by your browser's audio features, with no sound file and no network request. If your browser blocks audio until you interact with the page, pressing Start once is enough to allow it. Nothing is stored and no data is sent anywhere.
