Questions and answers
How many 30-second timers make a minute?
Two. 30 seconds is half a minute, or 0.5 minutes.
Why do the blocks change colour so early?
On short timers the "almost done" stage starts at half the time, so on 30 seconds the blocks turn orange at 15 seconds left and red with stripes in the last few seconds.
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.
