Free online stopwatch with laps, countdown timer and Pomodoro timer. Precise, with sound alerts. Works on any device, no download.

Chronometer vs timer (and how to use both)

A stopwatch measures elapsed time (from a start gun); a timer counts remaining time (to a deadline). Training, cooking and experiments typically need both — laps on the way, a bell at the end — which is why this tool includes the Pomodoro cycle alongside the chronometer.

• Laps capture intervals without stopping the clock — the right way to time workout rounds, repeated experiments or customer-service handling steps.
• Centiseconds matter when comparing runs; they are noise when boiling eggs. The display gives you both without clutter.
• Keyboard-friendly: space starts and stops — much faster than mouse hunting when your hands are busy (or floury).
• Pomodoro built in: 25/5 focus cycles with a rest reminder — no need to reset a kitchen timer eleven times a day.

Everything runs locally: closing the tab resets it, keeping the stopwatch honest (no accidental eternal runs) and your data private.
