Frequently asked questions
How accurate is this stopwatch?
It measures time down to fractions of a second using your browser's timing functions, which is accurate enough for most everyday timing needs.
Will the stopwatch keep running if I switch browser tabs?
Generally yes, since the underlying timer continues running in the background, though very old or restrictive browser settings could affect this.
