Frequently asked questions
- How do I record lap times with the online stopwatch?
- Start the stopwatch and select Lap whenever you want to record a split. Each row shows the lap duration and the total elapsed time.
- Will the timer still alert me if I switch tabs?
- Usually, but browsers slow down background tabs to save power, so the alert can fire a little late. Keep the tab active for time-critical use.
- Does the stopwatch keep a history?
- Laps are kept for the current session and are cleared when you reset or close the tab.
