An app that allow you to use your tablet to control your PC game. The interface on the tablet is totally customsable: position, size, orientation, color, texture... The interface that you creat can be shared on an online library. I'm using it to play with KSP (there is a mod for KSP with this app), Star Citizen and Elite dangerous. and it really bring to immersion. the app have a built in Macro editor and the edition of the interface can be done directly on the tablet that is great when you feel a button or other slider, pad is not at the right place :)
