Excited to mention that our app Icebreak for couples just got approved by Apple.
The app has a lot of screens and moving parts, but we were able to tie everything together and launch it. We have just launched the iPhone app, and are expecting that Titanium is going to make porting to Android very easy :)
Thanks everyone for answering a ton of questions, most of them before we encountered them :).
good job!! I'll test it and let you know ;) regarding the android porting.. good luck!
