Pomodoro Timer
Work in focused 25-minute sessions separated by short breaks, with a longer break after every four. The timer switches sessions for you and rings at the end of each one.

How the Pomodoro Technique works
- Pick one task.
- Focus on it for one Pomodoro (25 minutes) — no email, no phone.
- Take a 5-minute break.
- After four Pomodoros, take a longer 15–30 minute break.
The fixed rhythm makes big tasks feel finite, keeps breaks honest and gives you a simple measure of effort: “this report took six Pomodoros”.
Choosing your own lengths
25/5 is the classic, but many people prefer 50/10 for deep work or 15/3 when concentration is hard. Change the minutes above — the timer remembers the rhythm until you reload. Students revising for exams often use 45-minute sessions to match real paper lengths.
Getting the most from breaks
- Stand up and move — even a walk to refill water helps.
- Look at something far away to rest your eyes.
- Avoid starting something you cannot stop in five minutes, like a video.

Frequently asked questions
Does the alarm work if the tab is in the background?
Yes. The alarm is scheduled on your device’s audio clock when the session starts, so it rings on time even when other tabs are open. Keep your volume on.
What counts as a completed Pomodoro?
A focus session that runs to the end. Skipped sessions are not counted.
Is 25 minutes scientifically optimal?
No single length is best for everyone. The value of the technique is the regular rhythm of focus and rest — adjust the lengths until they feel sustainable.
