title: How to query installed/recently ran aps in iOS for demographic purposes
body: <p>Is it possible to query 'installed apps', or recently ran applications in an iOS environment? Does Apple allow access to this level of user information? I'm interested in seeing a user's installed applications, so that I can be specific in targeting/providing relevant information. </p>
  
  <p>ex. A user has Turbo Tax and CalculatorHD installed, they would find information on Tax Help/Services to be of benefit.</p>
