Hi! I'm a bit confused about the ground station. Is the iPad ground station able to work with the PC version? Reading the manuals it would seems so as the HW is the same. I'm unsure if the PC version can just be downloaded or needs to be bought? Also, WTF is it with DJI, where is the Android version of the app? I have no plans on getting a iPad, but I do have a couple of android tablets, and a laptop will do just fine.
