I'm honestly thinking about creating an iOS app for the site. I need a side project to distract me from my other side projects.
It's a good idea, however I believe you would need to resort to scraping the site at the moment, as the API isn't implemented yet.
Damn, I haven't really looked into it much. Maybe I can get in contact with someone to get some JSON feeds set up.
The API seems to be on its way sometime this year according to their year in review for 2014. They refer to it specifically as mobile API, even. If you do manage to expedite the API development process, that would be nice though! Some interest in it myself as well.
