Frequently Asked Questions
Common questions and answers about the Online Stopwatch.
Is the online stopwatch accurate?
Yes. It uses your device's internal system clock and the Performance API to track elapsed time, ensuring extreme precision down to the millisecond.
Does the stopwatch work if I close my browser?
Because it runs in the browser via JavaScript, closing the browser tab will stop the timer. However, if you just switch to a different tab or minimize the window, the timer will continue running in the background.
Can I record lap times?
Absolutely. You can click the 'Lap' button while the stopwatch is running to record and save split times without stopping the main timer.
