Frequently asked questions
How accurate is the stopwatch?
Time is measured with the browser's high-resolution clock and shown to a hundredth of a second. Changing your device clock does not affect it.
Will I lose my time if I close the page?
No. The start time of a running stopwatch is stored on this device, so reloading or reopening the page shows the time where it left off. The Reset button clears it.
What is a lap and how do I record one?
A lap is a split time taken without stopping the stopwatch. Press the Lap button or the L key while it runs; each lap time and the total are listed, with the best and slowest laps marked.
