You don't have an option. Apple does provide software updates for longer, but the moment they're cut, most apps will stop getting updates. This is because Apple's lack of backporting APIs forces developers' hands to raise the minimum supported iOS version often. Android devices do receive less software updates, but your apps will keep supporting pretty old devices for the most part. Of course there's the security part, but that's a different issue.
