On my iphone6, even if I set alarm to go off at 9 am to repeat every Monday and Tuesday of the week, if I turn off the alarm to stop it from ringing after I wake up at 9 am Monday morning, I have to reset it to "on" before Tuesday 9 am for it to go off Tuesday at 9 am. Is there a way, or an app for it to go off both Monday and Tuesday at 9 am, setting the alarm only once?
