This is a pretty good VR player, lets you watch a movie on your Google cardboard and splits it to Side-by-side. It does feel like you are at the movies, which is pretty cool.
However, I did notice that it messed up pdf file handling for all other apps on my iPhone 6s. For some reason with the app installed, any pdf file in mail app, Outlook app, Box, Onedrive, Dropbox, etc doesnt preview and you cant open it any another app. Your phone basically fails to recognize what the extension ".pdf" is. I reinstalled all these apps and finally traced it to VR Player.
I did purchase the Pro version of VR player, but I had to uninstall to restore functionality. Fix the pdf issues and youve got a good VR Player app!!
