Frequently Asked Questions
Does the stopwatch keep running if I switch browser tabs?โผ
Yes. The stopwatch uses JavaScript timing that continues running even when the tab is in the background. However, the display update may pause in background tabs to save resources. When you return to the tab, the elapsed time will be accurate.
How accurate is the browser-based stopwatch?โผ
Browser stopwatches are accurate to within a few milliseconds, which is more than sufficient for most timing needs. For professional sports timing that requires sub-millisecond precision, dedicated hardware is recommended. Browser timing accuracy can vary slightly under heavy system load.
What is the lap time feature and how do I use it?โผ
Lap time records the elapsed time at a specific moment without stopping the stopwatch. Press 'Lap' to record split times โ useful for tracking running splits, exercise sets, or any activity where you need to measure intervals within a longer timing session.
