What is the Pomodoro technique?

It is a time-management method that alternates 25-minute focus blocks with 5-minute breaks, taking a longer break after every fourth block. This timer runs those cycles for you and counts the sessions you finish.

Can I change the focus and break lengths?

Yes. Set any number of minutes for the focus block, short break and long break. Changes apply to the current phase when the timer is paused.

What are the default intervals?

The classic 25 / 5 / 15 setup — 25-minute focus blocks, 5-minute short breaks, and a 15-minute long break after every fourth focus session. You can override all three.

When does the long break happen?

After every fourth completed focus session the timer automatically schedules the long break instead of a short one, then the four-session cycle starts again.

Will it alert me when a block ends?

Yes. A tone plays via the Web Audio API when each focus or break block finishes, and the timer switches to the next phase automatically so you do not have to watch the clock.

Why use the Pomodoro technique?

Short, timed focus blocks make large tasks feel manageable, reduce procrastination, and build in regular rest so you sustain concentration over a longer day.

Is anything sent to a server?

No. The timer runs entirely in your browser using JavaScript and the Web Audio API. No timings, settings or session counts are ever uploaded.

A Pomodoro timer that runs in your browser

The Pomodoro technique breaks work into focused 25-minute blocks separated by short breaks, with a longer break after every fourth block. This timer automates the whole rhythm so you can just work: start a focus session, get an audible cue when it ends, and let it switch to the right break for you.

How it works

The timer cycles through three phases and counts completed focus sessions:

focus block (default 25 min)
 → short break (default 5 min)
 → repeat; after every 4th focus session → long break (default 15 min)
a tone plays at each phase change; the session counter increments per focus block

All three lengths are editable, and the completed-session counter tracks your focused work.

Example

With the classic 25 / 5 / 15 settings, one full cycle of four focus sessions runs:

4 × 25 min focus = 100 min focus
3 × 5 min short breaks + 1 × 15 min long break = 30 min break
The counter reads 4 completed sessions after the cycle

Phase	Default	After 4th session
Focus	25 min	25 min
Break	5 min (short)	15 min (long)
