What do you look for in Mobile banking app?

I was wondering i'm sure most of you have online banking account, so i was wondering as for a banking app for iphone or ipad etc.

what is the most thing you guys look for in an app? What is the thing you wish your bank had in that online banking app? E.g maybe graphs showing you how much you spend for the last week or month? Maybe transfer money button?

I'm asking due to a research I have to do. So your answers would be much appreciated! Only serious answers please!

You want the kind of app they have in the movies, which take pennies off of other peoples apps, and give you huge returns!
