Questions about the timer
Does it keep running in another tab?
Yes. The countdown follows the clock, not the screen, so it is right when you come back.
How long can it run?
From 1 minute up to 120 minutes.
Can I turn the sound off?
Yes. Press the speaker button at the top of the timer. Without sound, the screen still flashes when time is up, until you press Stop.
Does it keep ringing?
Yes, until you press Stop, the Space bar or Enter. If nobody does, it goes quiet on its own after 5 minutes.
