Stopwatch & Timer

Stopwatch with lap times and countdown timer with alarm.

Stopwatch & Timer combines a precise lap stopwatch with a countdown timer that ends in a clear alarm. Start, pause and reset the clock, record split times for intervals or exam sections, and review the full list of laps with their totals before copying them out. The timer lets you set hours, minutes and seconds, keeps counting accurately when the tab loses focus, and flashes the page title so a running countdown is visible even when minimized. Large readable digits, keyboard shortcuts and an optional ticking sound make it practical for workouts, cooking, presentations and classroom practice. Everything runs in the browser, so the tool works offline and asks for nothing.
