Its all about streaming from one device to another to another. It is a great experience. You can only do all the streaming if you are close to your Xbox one. You cant play your Xbox outside because obviously you need your controller.
SplashTop 2 is the last piece of the puzzle to actually play your Xbox one unto your smartphone. Love this app. Keep improving.
