A lot of potential!

Really cool! Just wanted to give some feedback on a few things I noticed on my iPhone 6 with a Google Cardboard viewer: First, the resolution was a bit low, I know the iPhone has a very high-res display, it’s probably a bandwidth tradeoff issue but you could go higher resolution. At the same time I noticed pauses and delays, although I have a great WiFi connection, perhaps some better technology is needed for buffering the videos.
Finally and most easily fixable, in Cardboard mode you have a white bar at the top of the screen that says “Google Cardboard move” and at the bottom when the video needs to load, little green loading bars appear. Both of these are visible within the 3D Cardboard view, appearing on the far left and far right and are distracting and take away from the immersive illusion.
