The Pomodoro Technique

The Pomodoro Technique turns a big, vague block of work into a series of small, concrete sprints. You pick one task, run the timer, and commit fully until it rings — then you rest for a few minutes. The rhythm of effort and recovery keeps fatigue in check and turns starting work into a low-stakes decision: just one 25-minute round.

Why 25 minutes?
Twenty-five minutes is long enough to get into real flow on most tasks, but short enough that sitting down for "one round" feels easy even when motivation is low. The number itself is a default, not a rule — many people adapt it to their attention span once the habit sticks.
The tomato-clock principle
The name comes from the kitchen tomato timer Francesco Cirillo used while a student in the 1980s. The core idea is that a finite, visible deadline is more motivating than an open-ended "work on it" plan. Each ring marks a completed unit of work you can count — that tally is what the sessions counter tracks here.
When does the long break happen?
After a set number of consecutive focus sessions — classically four — you take a longer break instead of a short one. The long break (15 minutes by default) gives your mind a real reset before the next cycle. This tool switches to the long break automatically after every N completed focus sessions.

Frequently Asked Questions

Why do pomodoros last 25 minutes?

Twenty-five minutes is a sweet spot found by Francesco Cirillo in the 1980s: long enough to build real momentum on a task, short enough that the commitment feels easy to start. The exact length is not sacred — many people stretch or shrink their sprints once the habit is established.

How does the Pomodoro Technique work?

You pick a single task, set the timer, and work on it with full focus until it rings. Then you take a short break of a few minutes. After every few pomodoros you take a longer break. The idea is that visible, finite work bursts beat open-ended 'I'll work on it later' sessions.

When should I take a long break?

Classically, after four consecutive focus sessions. This tool does the same automatically: once you complete your chosen number of focus cycles (default 4), the timer switches to the long-break duration instead of a short break, then returns to focus.

What happens when I close the page?

The timer stops. Everything runs in your browser with no server, so the running state and session count live only in this page. Reopen the tool and the counters reset to a fresh cycle.

Can I change the durations?

Yes. Focus, short-break and long-break durations are all adjustable in minutes, and you can choose how many cycles to finish before the long break. Changes apply to the next phase, and the current phase keeps its remaining time unless you press Reset.

If silence is what breaks your focus, cover it: keep the Noise Machine playing under the session, land every transition with a minute in the Breathing Timer, or hold a steady working pace with the Metronome.
