How this works in your browser
The timer alternates between focus and break phases automatically, computing remaining time from timestamps rather than counting down a stored value so that a throttled background tab does not cause drift. When a phase ends the next begins immediately with an alert, which is the mechanism that makes the method work: the transition is imposed rather than left to your judgement at the moment you are least inclined to exercise it. Both interval lengths are configurable, since the traditional twenty-five and five is a starting point rather than a rule, and longer focus blocks genuinely suit work with a high setup cost. Nothing is stored or transmitted.

Frequently asked questions
What is the traditional Pomodoro interval?
25 minutes of focus followed by a 5 minute break is the classic pattern, though both lengths are fully customizable here.
Does it automatically switch between focus and break?
Yes, when one phase ends the timer automatically starts the next phase and shows an alert.
Does it keep running if I switch tabs?
Yes, as long as the browser tab stays open, the timer keeps counting in the background.
Why does the technique work?
Because a fixed short interval makes starting easier and interruptions easier to defer. Committing to twenty-five minutes is a much lower barrier than committing to a whole task, and knowing a break is coming makes it reasonable to postpone a distraction rather than act on it immediately. The timer is a commitment device more than a measurement.
Should I stop mid-flow when the timer goes?
Not necessarily, and rigid adherence is where people abandon the method. If you are genuinely absorbed, keep going; the technique exists to help you start and to stop you working past exhaustion, not to interrupt work that is going well. Take the break when the momentum naturally breaks.
What interval should I use?
Twenty-five and five is the traditional pattern and a reasonable default. Deep work that takes a while to get into often suits fifty minutes with a ten-minute break, since the setup cost is paid less often. Both lengths are adjustable because the right interval genuinely varies by person and by task.
What should I actually do in the break?
Something away from the screen. Standing up, walking, looking at something distant and getting water all restore attention. Switching to social media or email does not, because it keeps the same faculties engaged, which is why breaks spent that way leave you no fresher than before.
