Yes i have a lil. to my knowledge for gear VR there is no app . to use it you have to install your phone in a manner that keeps it from getting plugged into the USB port or it will automatically load gear VR software. Ok theres litchi but its $25 never tryed.. i have drone vr.$10. Work cool I just haven't figured out how to get the camera to record with drone VR it's supposed to be voice activated..and i use a cheap vr headset.
The recently update Litchi app ($20) works great with my new Blitswolf VR glasses, it's really amazing how it responds to head movement (left/right, up/down) to control my P3A.
