Pomodoro Study Timer

It's the original Cirillo length — short enough that anyone can hold attention, long enough to make real progress on a problem set. Filipino learners doing board-exam reviewers often run longer (50 or 60 minutes) once they get into flow; the duration knobs below let you tune it.

Use it on days when your motivation is wobbly or you have a deadline. On days when you're in flow, just keep going. Pomodoros are scaffolding, not a religion.

Every 4 focus blocks, take a 15–30 minute long break. Get up, eat, walk. Brain consolidation happens during these — skipping them is why some reviewers feel sharp at hour 2 and useless by hour 6.

Yes — a soft chime when each phase ends. Tab volume controls it. If sound is muted (e.g. you're at a library), the document title also flashes 'BREAK!' or 'FOCUS!' so a glance still tells you.

Pick any focus / short / long duration in the form. We don't store anything in localStorage — refresh the tab and you're back to defaults. Keep this open in a pinned browser tab if you want to keep streaks.
