Pomodoro Timer
Run focused work sessions with automatic short and long breaks using the Pomodoro Technique — auto-start, browser notifications, a daily session count, and keyboard shortcuts. Runs entirely in your browser.
This works right here on your device — nothing gets sent out.
Sessions completed today: 0 · Shortcuts: Space start/pause, R reset, S skip
How it works
- Optionally adjust the focus, short break, and long break durations, and how many focus sessions happen before a long break — your settings are remembered for next time.
- Click Start to begin the countdown — the tab title updates too, so you can track progress from another tab.
- When a session ends, a chime plays (and a browser notification too, if you've turned that on) and it lines up the next session — turn on "Auto-start the next session" to skip clicking Start each time, or click it yourself when you're ready.
- Use Skip to jump ahead, or Reset to start the whole cycle over. Space, R, and S work as keyboard shortcuts for Start/Pause, Reset, and Skip.
- Your "Sessions completed today" count updates after each finished focus session, so you can see your progress at a glance.
This follows the classic Pomodoro Technique: alternate focused work with short breaks, and take a longer break after a set number of focus sessions — by default, 25 minutes of focus, a 5-minute short break, and a 15-minute long break every 4 sessions.
FAQ
Does the timer still run if I close this tab or put my laptop to sleep?
No — it needs the tab open (in the background is fine) and your device awake, the same as any browser-based tool. Closing the tab or letting your laptop sleep stops the page's JavaScript, which is what's tracking time.
Why do I have to click Start instead of the timer running automatically?
Browsers block audio from playing until you've interacted with the page, so clicking Start is what unlocks the chime for later — the countdown itself only begins once you click it too.
Can I change the durations partway through a session?
The duration fields lock once you click Start, so a running session can't drift out of sync with its countdown. Click Reset to unlock them and start over with new durations.
What's the difference between Reset and Skip?
Reset stops everything and returns you to the first focus session from zero. Skip ends only the current session immediately and moves on to the next one in the cycle — your session count keeps going.
Is any of this sent anywhere?
No. The countdown and chime run locally using your browser's built-in timer and Web Audio APIs — nothing about your sessions is uploaded or logged. Settings and your daily session count are saved only in this browser's local storage, never to a server.
Can the timer start the next session automatically?
Yes — turn on "Auto-start the next session" and it moves straight from focus to break (and back) without you clicking Start each time. Leave it off if you'd rather confirm you're ready before each session begins.
Can I get a notification when a session ends, not just a sound?
Yes — turn on "Show a browser notification when a session ends" and your browser will ask for notification permission once. If you allow it, you'll get a system notification even if the tab is in the background, in addition to the chime.
Does it track how many sessions I complete?
It keeps a "Sessions completed today" count that updates as you finish focus sessions, saved in this browser and reset each day — no account or sign-up needed.

A generic phone timer works, but you have to set the focus timer, then the break timer, every single cycle. Pomodoro Timer tracks the whole work/break rhythm for you — start once and it lines up the next session automatically (or on its own with auto-start), keeps a running count of today's finished sessions, and can notify you when one ends — all without the install or account some dedicated Pomodoro apps ask for.
