Pomodoro Focus Timer

It is a time-management method developed by Francesco Cirillo in the late 1980s. You work in fixed focus intervals — traditionally 25 minutes, called one "pomodoro" — separated by short breaks, and take a longer break after four of them. The idea is to work with your attention span in short committed bursts rather than fighting fatigue through a long unbroken session.

Yes, and this is where many web timers fail. Browsers throttle background tabs, so a timer that simply counts down once per second falls behind when it is not the active tab. This one records the exact clock time each session should end and works out the remaining time from your device clock on every tick, so when you come back it shows the correct time rather than a value that lagged behind real minutes. The tab title also shows the live countdown.

The classic 25 minutes is a good starting point, and it is the default here. If you find yourself repeatedly interrupted before the bell, try a shorter block; if you routinely hit a deep flow and resent stopping, a 45–50 minute focus with a 10-minute break often suits analytical or creative work better. The right length is the longest one you can hold attention through without drifting — adjust the fields and see what fits.

The timer gives you a long break instead of a short one. Counting completed focus sessions and inserting a longer rest every fourth is part of the original technique — the longer pause lets your attention genuinely recover before the next cycle. The completed-session counter on the timer tracks how many focus blocks you have finished so far.

The timer runs entirely in your browser with no account and no server, and it does not persist across a full page reload — the completed-session counter and any custom durations reset when the page reloads. This keeps it private and dependency-free, but it means it is a within-session focus aid rather than a long-term study log.
