Frequently Asked Questions
How accurate is this online stopwatch?
It updates in real time using the browser's high-resolution timing APIs. Like any browser-based tool, tiny display variations can happen if your device is under heavy load, but it is accurate enough for workouts, study sessions, cooking, and most everyday timing tasks.
What is a lap time?
A lap time measures one segment between presses of the Lap button, while total time shows the full elapsed time since the stopwatch started. This is useful for tracking intervals, splits, and repeated tasks.
Can I use keyboard shortcuts?
Yes. Press Space to start or stop, L to record a lap on the stopwatch tab, and R to reset the active stopwatch or timer.
Will the timer make a sound when it ends?
Yes, if you keep the sound alert option enabled. The timer uses a simple built-in browser beep so you do not need to upload audio files or install anything.
