A stopwatch with laps

Press Start, then Lap at each split. Space starts and stops, and L takes a lap.

Stopwatch

0:00.00

Keeps exact time when you switch tabs, and says if it ended while you were away. Keep this page open for the sound, especially on a phone, where browsers may pause a page in the background.

How it works and help
Sounds are made in your browser and nothing is sent anywhere. A running timer is kept only for this tab, so a reload carries on.

A little help along the way

Follow these steps. Every option is explained underneath. Everything runs in your browser; nothing is sent anywhere.

  3. Press StartThe sound is set when you press Start. Pause, carry on, add a minute or reset at any time.
  4. Hear it endIt rings at the end and says when it finished, even if you looked away.

Questions people ask

What is the difference between a lap and a split?
A lap is the time since the last press; the total, often called a split, is the time since the start. The stopwatch shows both for every lap.
How precise is it?
It shows hundredths of a second, worked out from the moments you pressed. Your own reaction, about a fifth of a second, matters far more than the clock.
Can I save my laps?
Press Copy over the laps for a table you can paste into a spreadsheet: the lap, its time and the total.
