The Pomodoro technique works because a defined block is easier to start than an undefined one — twenty-five minutes on one task is a commitment you can actually make at nine in the morning. This free Pomodoro timer runs in a browser tab with no account and no upsell.\n\nFocus length, short break, long break, and the number of rounds before a long break are all adjustable, because the classic 25/5 is a starting point rather than a rule. Plenty of people find 50/10 fits deep work better, and shorter blocks suit shallow admin. Phases can advance automatically so a break does not quietly become twenty minutes.\n\nOne technical detail that matters more than it sounds: timing runs against the wall clock rather than counting down ticks. Browsers throttle timers in background tabs, so a naively implemented countdown genuinely loses time whenever you switch away — which is precisely when you are supposed to be working. This one stays accurate.\n\nA progress ring makes the remaining time readable at a glance from across a desk, and a chime marks each transition. Nothing is stored or uploaded. Pair it with the Online Notepad to capture what surfaced during a session, or the Stopwatch & Timer when you need plain timing instead.

Timing runs against the wall clock rather than counting down ticks, so it stays accurate when the tab is in the background — browsers throttle background timers, which makes naive countdowns run slow.
