Frequently Asked Questions
How accurate is this stopwatch?
The stopwatch uses the browser's high-resolution performance timer, which provides sub-millisecond accuracy. It is more than precise enough for any practical timing need.
Can I record lap times?
Yes. Click the Lap button during a running timer to record a split without stopping. All laps are displayed in a table with individual and cumulative times.
Are there keyboard shortcuts?
Yes. Space starts and stops the timer, L records a lap, and R resets the stopwatch. These shortcuts let you operate the timer without looking at the screen.
