Pomodoro Timer

Pomodoro Timer is a free online focus timer that runs the classic Pomodoro Technique — 25 minutes of focused work followed by a 5-minute break, repeated — entirely in your browser. After four work sessions it switches to a longer 15-minute break, helping you sustain concentration over long tasks like studying, writing, or deep work.

About Pomodoro Timer

Pomodoro Timer is a free online focus timer that runs the classic Pomodoro Technique — 25 minutes of focused work followed by a 5-minute break, repeated — entirely in your browser. After four work sessions it switches to a longer 15-minute break, helping you sustain concentration over long tasks like studying, writing, or deep work.

Pick a scene-based preset — Classic (25 / 5), Short burst (15 / 3), Study (50 / 10), or Deep work (90 / 20) — or open the settings panel to dial in your own work minutes, break minutes, long-break minutes, and how many sessions you want before the long break. A large circular progress ring shows the remaining time at a glance, and each phase ends with an alarm sound (four built-in tones to choose from) and an optional browser notification.

Full-screen mode lets you turn the whole tab into a focus screen, and on supported desktop browsers a Picture-in-Picture pop-out keeps the timer always on top of every other window — so you can keep coding, reading, or studying in another app without losing sight of the countdown. The remaining time also appears in the browser tab title, making it easy to glance from any other tab. Your settings and today's session count are stored only inside your browser; nothing is sent to a server. Runs entirely in your browser.

How to use

  1. Pick a scene-based preset (Classic, Short burst, Study, or Deep work) that matches today's task, or open Settings to set your own work, short break, long break, and sessions-before-long-break values.
  2. Type what you are focusing on into the “Current task” field (optional — leave it blank if you prefer).
  3. Press Start. The work session begins and the circular ring plus the central MM:SS countdown show the remaining time.
  4. When the session ends, an alarm plays and the timer switches to a break automatically. Turn off auto-start if you'd rather start the next phase manually.
  5. After four completed work sessions the timer switches to your configured long break. Use Skip to end the current phase early.
  6. Use the buttons in the top-right to go full screen or open the Picture-in-Picture pop-out, so the timer stays visible while you work in another app.

Use cases

  • Students preparing for entrance exams or certifications who want to break long study sessions into 25-minute blocks and keep their focus sharp.
  • Remote and hybrid workers who need to ignore chat and notifications during deep-work windows.
  • Writers, engineers, and researchers who do long stretches of solo thinking and want to enforce regular short breaks.
  • Anyone who needs a quick focus timer or study timer in the browser and does not want to install an app.
  • Parents and tutors who want to give online lessons or homework sessions a clear, predictable rhythm.

Notes

  • The Picture-in-Picture pop-out uses the Document Picture-in-Picture API, which currently works on Chrome / Edge 116 and later. On Safari and Firefox, use full-screen mode instead.
  • Enabling browser notifications triggers the permission prompt the first time. Once granted, the timer can notify you when a session ends even if the tab is in the background.
  • The timer is driven by a target end time, so it stays accurate even if the tab is throttled in the background.
  • Alarm choice, notification preference, timer settings, and today's session count are all saved to your browser's localStorage and do not sync across browsers or devices.
  • This tool is completely free and requires no sign-up. Task names and session times stay in your browser and are never uploaded.

FAQ

What is the Pomodoro Technique?
A time-management method created by Francesco Cirillo in the late 1980s. You work in 25-minute focus blocks called Pomodoros separated by 5-minute breaks, and after every four Pomodoros you take a longer 15–30 minute break. The structure makes it easier to start hard tasks and to stay focused for long sessions.
Is it really free? Do I have to sign up?
Yes, it is completely free with no sign-up. Just open the page in your browser and start the timer. There are no ads in the timer view, and task names and session times are never sent to a server.
Can I customize the work and break lengths for studying?
Yes. Open Settings to type your own values for work, short break, long break, and the number of sessions before the long break. The Study preset (50 minutes work / 10 minutes break) is a good starting point if you want longer blocks closer to a typical class period.
Can the timer stay visible while I use other apps?
Yes — press the Picture-in-Picture button and the timer pops out into a small window that stays on top of every other application. It uses the Document Picture-in-Picture API and works in Chrome / Edge 116 or later. The remaining time also appears in the tab title, so you can see it from any other tab.
I can't hear the alarm — what's wrong?
Browsers block audio until the first user interaction. Press Start once and audio will play for the rest of the session. If it still doesn't sound, use the “Preview sound” button in Settings to check the volume and your system mute state.
Does the timer remember my work history?
It keeps the number of sessions you finished today inside your browser, and resets the counter when the date changes. It does not store a detailed work log. If you want a permanent record, copy the count into your task manager or journal.
