常见问题

Does it keep running if I switch tabs?

Yes. The timer follows your device's clock, so it stays right while you use another tab; the ring may come up to a second late then.

Why is there no sound?

Check that "Ring when time is up" is on and your device isn't muted. Some browsers only allow sound after you click on the page, which Start does.
