Ok, but what I've wondered about this is HOW OFTEN do apps actually bother to update - how often does iOS actually take action and update apps? Every time I check on my wife's phone for whatever problem she's having, one of the first things I do is check for apps needing updates. She always has like 40 apps needing updates even though she has the automatic updates turned ON in Settings -> App Store, even though she plugs in every night for charging, and her phone is on the house wifi just fine.
So on *my* phone I feel compelled to manually check for updates every single week. PITA.
