They are working on third party app similar to Litchi & Autopilot. Litchi was released early 2014, in the beginning it was buggy with all kinds of problems:
Litchi app
The X-Star Premium is new drone in the market with a great customer service, and that is enough for me. I own both drones, I feel that I am gambling when it comes to buying a DJI product, I am always worried that if I have to contact service is going to take an act of congress for them to get back to me. I have peace of mind when it comes contacting Autel's customer service.
As far as distance goes, in a good day I have gotten 2.9 miles on the X-Star, oh, and no cracked shells. The build does not feel cheap.
The X-Star Premium is designed with an easily removable gimbal which only requires the push of a button on the side of the gimbal to slide it off. This feature will allow the camera to be easily upgraded as payload technologies advance.
Autel added an LCD display to the controller itself which provides critical flight telemetry data such as altitude, range, battery remaining (for both the remote and the AC), gimbal's tilt, AC's orientation, etc. This redundancy provides an increased margin of safety and allows the pilot the option to use the full screen of the external display to view video coming back from the drone at 720P. Let's say that the battery of your tablet or phone dies or that your flying app collapses while you are flying the drone, with X-Star Premium you have an actual LCD that tells you everything you need to know to bring your drone back home safely.
