Pomodoro Timer

From the tomato-shaped kitchen timer Cirillo owned as a university student, which had a maximum setting of 25 minutes. The length balances easy starting with real depth and became the classic after decades of use — but it is not mandatory, and you can adjust it to any duration that works for you.

The classic rule says a pomodoro cannot be split: once a true interruption happens (a call, an urgent request), the round is void and you begin a fresh 25-minute block afterward. Brief pauses like taking water off the stove can use the pause button, but frequent pausing usually signals that the task needs to be broken down further or the environment adjusted.

Four pomodoros plus three short breaks span about two hours, after which accumulated fatigue noticeably deepens and 5 minutes no longer restores attention. A 15–30 minute long break lets the brain enter its resting-mode network and process what it just absorbed, so focus quality rebounds. You can change the long-break interval in settings.

With browser notifications allowed, an alert appears in the corner of your screen when a phase ends, even if you are in another tab or the window is minimized — combined with the chime, you can safely handle light tasks while waiting for a break. Notifications are generated locally by your browser; this tool connects to no push server and cannot reach you after the page is closed.

Your duration settings and daily stats are stored locally in this browser via localStorage, so they survive refreshes and browser restarts, but clearing browser data or switching browsers or computers will not carry them over. Timing is entirely client-side and works fully offline.

Beginners often feel a clear productivity boost from 4–6; experienced users commonly land at 8–12 per day. More than 12 in a row usually means breaks are being squeezed, which leads to burnout over time. Quality matters more than count — eight fully focused pomodoros beat fourteen timed while half-checking messages.

It works best for people who procrastinate, get easily interrupted, or want an external rhythm — but it is not the only way. Getting pulled out of deep flow by the 25-minute bell can be costly, in which case the 50/10 or 90/20 presets fit better. If timers make you anxious, mute the sound and treat it as a gentle break reminder; you always set the rhythm.

A plain timer handles one interval at a time. This tool cycles focus–short break–long break automatically, counts rounds, keeps daily stats, and links sessions to concrete tasks so you can see how many pomodoros each one took. It is a rhythm-and-feedback system, not just a ringing bell.
