There is an app called autopilot for djiDo you mean Autopilot by Autoflight Logic? DJI don't make an App called Autopilot.
If that's the one you mean, then yes I have it. I don't use it anymore though as the developers stopped updating it over a year ago, which means it won't be safe to use given all of the firmware updates we get. It also doesn't work very well because IOS has been updated since and it doesn't even fit the screen on my ipad Pro.
I'd recommend avoiding it.
