The iPhone’s Clock app has an alarm clock function that can wake you up in the morning by playing a ringtone or alert tone. But did you know, that even if you set the iPhone’s ringer switch to silent mode, the alarm will still go off and play its sound? It will.
So if you want the alarm to make noise and wake you in the morning, lay your sweet head to rest tonight without worrying about where the iPhone’s ringer switch is set. If you don’t want the alarm to go off, you’ll need to turn the alarm off in the Clock app.
