Timer & Stopwatch

About this tool

This free online timer and stopwatch does both: a countdown timer with an alarm sound when time runs out, and a stopwatch with lap times. Use the quick presets (1, 5, 10, 15, 25, 30 minutes or 1 hour) or set your own hours, minutes and seconds.

It runs entirely in your browser — keep the tab open while it counts.

Features

• Four alarm sounds — beep, bell, digital watch or gentle chime — ringing until you press Stop, or just once
• Ends at — the clock time it will finish, and +1 min while it runs

• Keyboard shortcuts: Space start / pause, R reset, F fullscreen
• Quick presets — 1, 5, 10, 15, 25, 30 minutes and 1 hour

• The time left in the browser tab, and the tab blinks when time is up
