About this countdown timer
Set any duration and start counting down. The Pomodoro Technique uses 25-minute work sessions followed by 5-minute breaks — try the built-in presets. The timer uses requestAnimationFrame for smooth display and runs entirely in your browser. Note: the timer may drift slightly if the browser tab is in the background, as browsers throttle inactive tabs.
Private & free — this tool runs entirely in your browser.
