Questions and answers
How many seconds is 9 minutes?
540 seconds, or 0.15 hours.
Can I change it to 9 minutes 30 seconds?
Yes. Open Settings under the timer, set minutes to 9 and seconds to 30, then press Start.
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.
