IPhone is a completely different animal. Apps don't exactly port very well across the two formats. It is something that has definitely been asked of me a number of times, but since Flica already has an app, I have left that alone. I might still attempt something once the dust settles on the Android app, though.
I have to reacquaint myself with a programming language that I haven't used in quite a while, but it might be worth it.
I'll keep you guys posted if I attempt something.
