Just wanted to showcase a little app I did with C2.
It's basically a news aggregator with several popular news sources, including some for games.
You can get it on the Google Play Store
It was actually quite easy to do using the ajax plug to connect to an excellent api. I developed it in just about a week.
In fact I think using C2 for apps is quite plausible, and am thinking of doing a few more, as I rather like making graphical user interfaces.
The only issues are every thing has to be done from scratch. There's no built in methods to create the many interface features like menu scroll, swiping etc.
I just pushed the android release last night, and haven't had much input on it, so please give it a try, and tell me what you think.
