I’m using Codea on my iPad, and I just updated to version 3.0. I’m glad to see that Codea is available for iPhone now. However, when I try to download Codea to my iPhone from the app store, it looks like it is going to charge me $14.99 again. Is that by design, or is there something that I need to do differently in order to put Codea on my iPhone without paying again?
