* The app faithfully implements all features of the iPhone app that were publicly documented last summer, including rj_image, rj_text, sensor input, etc. There have been a few additions since (scaling and rotating text, I think); those will be easy enough to add when I see the new specs, and I'm not aware of any scenes that require them. In short, a properly written RjDj scene should look and behave the same for both versions.

How do you want the spec Peter? As a Pd patch showing how to use it? I'm going to update the help patch for [rj_image] in the RjLib, would that be useful?

Ideally, I'd like to have a list of all externals and their messages, including an explanation of the meaning of parameters (e.g., units, origin and orientation for coordinates and angles, etc.), as well as test scenes/help patches and maybe videos of how it looks and behaves on an iOS device. Realistically, updated help patches would probably be enough to get me started.

This is really cool Peter. Thanks for you all your work! I don't know about Martin, but I don't think many of us in the company are that update with the Android development - being that we all have iPhones :)

You're welcome!
Cheers,
Peter
