How to use the Online Stopwatch
Using the stopwatch is simple and intuitive. The counter displays the elapsed time in hours, minutes, seconds and milliseconds. Click on "Start" to initiate the counting. To pause the running interval, click on "Stop". To resume it, just click on "Start" again. To reset it, click on "Clear" to revert it to the initial settings.
The stopwatch works with minimized apps, inactive tabs and with the phone in sleep mode. The elapsed time will not be interrupted when you turn off your device screen or when you minimize your browser.
