Yes. Time is measured from the clock, so it stays accurate even if you switch tabs. Keep the page open to hear the alarm.
Why didn't I hear the alarm?
Check your volume and that the phone isn't on silent. Some browsers only play sound after you've tapped the page once.
How accurate is the stopwatch?
It shows hundredths of a second and uses your device's high-resolution clock.
Can I record lap times?
