I'm working on my first app, and I want to be careful to avoid violating restrictions that will prevent it from being listed. My question is about links to other products that may not be in the App Store.
What I mean is that along with the app's primary functionality, I want to include value by allowing it to connect to other company's resource files that they sell or provide. I would have a Settings page that lets users set up a link to the files that they have on their machines. Can I provide a link to some of the popular resource files so users recognize that my app will work with those files — and the link would help them get those files.
For example, let's say I have a movie app and there were versions of IMDB or Rotten Tomatoes databases that they sold. Would I be able to specify the URLs for IMDB or Rotten Tomatoes so they know they could go buy the resource file from those companies and then incorporate it into my app?
