title: On which mobile analytics SDK can I define different types of users?
body: <p>I'm building an iOS app and would like to use a analytics tool (Flurry, localytics or others).
  My app will have 2 types of users, where some users can be of the 1st type, some can be of the 2nd type and some will be both kinds.
  On which analytics tool can I get adequate reports that take these 2 types into account? 
  Is there some kind of "tag" that I can use to identify the types of users, and then see those in the reports? For example, a report that shows users only from a certain type.</p>
