With Air, Starling/Feathers is a better choice for Mobile, HTML/JS is not a good choice for app, I use it only for the web.
For app, native, Unity or Air are the better choice I think. Air is not browser dépendent, is not the same problem that Flash Player. For game (not for Flex), I use OpenFl/Haxe to port my ActionScript code. -- Sent from: http://apache-flex-users.2333346.n4.nabble.com/
