I used this to download the app. just drop "https://play.google.com/store/apps/details?id=com.reelfx.legendary_vr" without parenthesis into it and you should be good to go. I recommend scanning the QR code for a direct download on your phone.
This VR demo is best viewed on your smartphone. You can tilt your phone to look around. Also compatible with Google Cardboard if you have one of those. You'll need to download the "movie" inside the app, which is 465.6MB so you might want to be on wifi.
