4 Ways to remove an IOS app: is there a preferred method? Per this article, there are 4 methods to remove an app:


tap and wiggle
from settings 
from iTunes
when updating


Is there an advantage / preference to use one of these methods over another?
Nope, no advantages between them. In my opinion, just doing a tap-and-wiggle from the home screen is most efficient, but each of the four ways you mention just removes the app. Do whatever's easiest in the moment.
