Questions and answers

How many seconds is 13 minutes?

780 seconds.

Does it keep time if my laptop screen dims?

Yes, as long as the computer does not go to sleep. If it sleeps, the timer catches up the moment you come back and rings at once if the time has passed.

Does the timer keep running if I switch tabs?

Yes. TimerNook works out the time left from your device clock and a fixed end time, not by counting ticks, so a background tab is still right. While a timer runs, the page also plays a tone too quiet to hear, so the browser keeps the tab awake; your browser may show a speaker icon on the tab. If you also tick "Notify me", you get a system notification at the end.

Will the alarm ring if my phone screen locks?

Not always. Phone browsers can pause web pages when the screen locks, and an iPhone on silent can mute browser sound. Keep the screen on; while the timer runs TimerNook asks the browser to keep the screen awake where that is supported. If the page was paused, the alarm rings as soon as you return.
