Frequently Asked Questions
How accurate is this stopwatch?
It uses the system clock (Date.now()) and updates every 10ms. Accuracy is within ~10-15 milliseconds, suitable for most timing needs.
What is a lap?
A lap records the current elapsed time as a checkpoint. The split shows how long each individual lap took.
Does it keep running if I switch tabs?
Yes. The stopwatch uses absolute timestamps, so it remains accurate even when the tab is in the background.
