Ive been using Packing Pro for years, and I never have to worry about forgetting anything. Ive got a default list of all the things I normally bring, but if I think of anything unusual for a particular trip (even weeks in advance) I just pop it on the list and I know itll be there when I need it.
Very full-featured app. We all think differently, and its got enough choices that you can adapt it to how you lime to do things.
