I look at lot of mobile banking apps. But there are several thousand in the U.S. alone, so I'm not going to claim that I know which one is "best" or even who should be in the top-100.
But I will say, of the mobile banking apps I'm familiar with, ANZ Bank's is right up at the top. Kudos to the bank and Fiserv's M-Com unit that helped with development.
Why is it so good? It's full featured, of course. But it's the first banking app that feels like it runs WITHIN the iPhone instead of being bolted on. It's almost like what Apple would have done if it was building a banking app right into the operating system (notes 1, 2, 3).
I especially like how the person-to-person payments function integrates with iPhone Contacts. And how iPhone's photo gallery can be used throughout the app to illustrate…
