title: How to identify iOS Universal apps from apple RSS feed
body: <p>I'm working on an iOS app review website and have taken a look at the tools Apple provides, such as iTunes RSS feeds and API.  </p>
  
  <p>However, I do not know how to distinguish an iOS Universal app from the other iOS app types (iPhone and iPad only).  </p>
  
  <p>Any idea how to make this distinction so I can segregate iOS Universal apps?</p>
  
  <p>Thanks!</p>
