I am pleased to announce that you can now read this blog (and also the Core Economics blog) on an iPhone app: CoreEcon. Click here to download it from the US iTunes App Store.
It is better than a web page because you can download the posts and read them when you are on a plane or something. And it is optimised for iPhone reading.
Given the fierce competition for attention, I have competitively priced it at $0. Clearly a must have.
