Pomodoro timer
Focus and break cycles, with automatic long breaks.
Pomodoro timer runs a focus/short-break cycle (25/5 minutes by default, fully adjustable), automatically switching to a longer break every 4th focus session — a structured way to work in sustained, distraction-resistant intervals.
Focus
25:00
Completed focus sessions: 0
How to use
- Set focus, short break, and long break minutes, or keep the 25/5/15 defaults.
- Click "Start" — the timer cycles focus → short break automatically, and switches to a long break every 4th focus session.
- The browser tab title shows the remaining time while a phase is running.
Common use scenarios
- Studying for an exam using timed focus intervals with built-in breaks.
- Working through a large task in structured, sustainable chunks.
- Building a consistent focus habit with automatic break reminders.
- Timing a writing or coding session to avoid working past the point of diminishing returns.

How we verify Pomodoro timer
How to confirm the timer cycles between phases exactly as configured.
Long break triggers every 4th focus session
The timer counts completed focus sessions and automatically switches to a long break after the 4th one — sessions 1, 2, and 3 are followed by short breaks, and only session 4 (and every 4th after that) is followed by the long break.
Tab title shows the countdown
While a phase is running, your browser tab's title updates to show the remaining time and current phase — useful for keeping track of your progress without keeping this tab in the foreground the whole time.
Timing pauses if the tab or device sleeps
Since this runs in your browser, closing the tab, putting the computer to sleep, or the browser being suspended in the background will pause the countdown — it's not a background service that keeps running independently.
Before you rely on the result
- Focus, short break, and long break minutes are set to what you actually want (or you're using the 25/5/15 defaults).
- You understand the long break triggers automatically every 4th completed focus session.
- You're keeping the tab open (not closing it or letting the device sleep) for uninterrupted timing.
- You've checked the tab title if you want to glance at remaining time without switching windows.
Who this is for
- Students studying for exams using timed, structured focus intervals.
- Anyone working through a large task in sustainable, break-inclusive chunks.
- People building a consistent focus habit with automatic break reminders.
- Writers, developers, or anyone wanting to avoid working past the point of diminishing returns.
Real-world examples
Structuring an exam study session
A student studying for finals uses the default 25/5/15 cycle to work through material in focused bursts, taking the automatic long break after every fourth study block to avoid burnout.
Working through a large writing project
A writer breaks a big writing task into pomodoro-sized chunks, using the built-in breaks to step away from the screen regularly rather than pushing through fatigue.
Building a daily focus habit
Someone trying to build a consistent work routine uses the timer every morning to structure their first few hours, relying on the automatic phase switching to remove decision fatigue about when to break.
Limitations
- Timing runs while this tab is open; closing the tab or letting the device sleep will pause the countdown.
- The reminder sound needs a prior click on the page before it can play, due to browser autoplay rules.
Frequently asked questions
Can I change the default 25/5/15 minute settings?
Yes — all three durations (focus, short break, long break) are fully adjustable before you start; the defaults are just a commonly used starting point.
What happens after the long break ends?
The cycle continues — the timer goes back to a focus session, and the count toward the next long break (every 4th session) continues from where it left off.
Will the timer keep running if I close the browser tab?
No — timing only runs while the tab is open; closing it, or letting your device sleep, pauses the countdown since this isn't a background service.
Can I skip a break or jump straight to the next focus session?
The timer follows the standard focus → break → focus cycle automatically; if you want to end a phase early, use Reset and start a new session rather than trying to skip ahead mid-cycle.
