The app is particularly addictive if you have time on your hands, you can just keep browsing.

I tried browsing for a few minutes, but I got bored quickly.

Pretty much I'm convinced the site & app will be successful. :)

iOS development is not only objective-c and Cocoa Touch. XCode, interface builder, instruments are also big helpers and sometimes there can be memory problems that you can only trace with instrument.

Definitely. I know RubyMotion currently supports XIBs and Storyboards, but yeah there's no integrated solution with Xcode or Instruments right now. I personally like the Rake-based approach, its more lightweight than booting up an IDE, but I would bet that better Xcode support is possible since MacRuby already does it pretty well.

That's if you like using interface builder. I personally dislike it and prefer to lay things out programmatically, but this probably has to do with the fact that I came to iOS development from the web development world.

I also try to not use IB most of the time, but especially if you are building not so custom designs, IB really increase the productivity and keep the code clean.

Nitron has [slightly hacky] support for IB: https://github.com/mattgreen/nitron

Check the tutorial for an explanation of how to use it. Disclaimer: I'm the author. :)
