Pomodoro Timer

The Pomodoro Technique, worked out by Francesco Cirillo in the late 1980s, is not really a productivity trick — it is a schedule: one focused block of work, a short break, then a longer break after a set number of blocks. The usual numbers are twenty-five minutes of work, five minutes off, and a long break of fifteen to thirty minutes every four rounds, and that is exactly what this timer starts with.

The work block is meant to be one subject, uninterrupted. The break is meant to actually be a break, away from whatever you were just doing. The round counter matters more than it looks like it should: it is what tells you a long break is due, and it gives a study or work session an actual shape instead of an open-ended stretch that just ends whenever you get tired.

There is no solid number for how much a timer boosts anyone's output, and any page that hands you a percentage has made it up. The research on scheduled breaks and timeboxing is real, but it is modest and varies a lot by task and by person — it does not support one specific figure, so treat any number you see elsewhere as marketing.

What the technique reliably does is procedural, and that is where the value actually is. A fixed block makes starting cheaper, since you are only committing to twenty-five minutes, not the whole task. It makes interruptions obvious, because you notice the moment one lands mid-block. It forces the break to actually happen, which is the first thing anyone busy tends to skip. And it gives a session a unit you can count in rounds instead of vague hours, handy for a long review stretch before a board exam or a big deadline.

If twenty-five minutes does not fit your work, change it. The number is not the point — some tasks need fifty minutes to get anywhere, some people do better at fifteen. What matters is that the block has an end, the break actually happens, and you keep the same shape long enough to tell if it is working for you.

Set your focus length, short break, long break, and how many rounds come before a long break — the page remembers all of it in your browser for next time. Turn on auto-start, and the next interval begins on its own, which is what you want when the cycle itself is the point; leave it off, and each interval waits for you to press Start, which works better when a block sometimes needs to run over.

The time left shows in the tab title as well as on the page, so it is readable from across a desk, and a chime marks the end of every interval. Same as everywhere else on this site, the reading comes straight from your device clock instead of a tick count, so a block spent in a background tab still ends exactly on time. Skip jumps to the next interval, and reset brings the whole cycle back to the start without losing your settings. For a one-off length of time instead of a repeating cycle, the timer is simpler; for time that has already passed, the stopwatch measures that instead.
