I've heard it said, while the masses own Android, venture capitalists tend to own iPhones. So to get those with money interested in your project, you make an iOS app version first. (I have no clue if this is true, just saying what I heard)

Anyway, I'm happy to see a Bitcoin app because I have an iPhone. But you should be happier, your Android seems to have a lot more Bitcoin potential than my walled-garden device does.
