Anything GPL licensed that is on the iOS App Store is in violation of the GPL unless they own the copyright to all of the code in the app and are effectively dual licensing it. That's the way it's been explained to me due to the restrictive way that the App Store agreement is structured (more restrictively than the Play Store, Amazon App Store, etc).
