Works perfectly fine on my iPhone 6s Plus. The theater design and dynamic lighting are great. Great options to adjust the barrel distortion and screen size etc.
A few suggestions to make it better:
1. The drifting is problematic. The drift correction option is annoying and it would be better to just fix the problem altogether.
2. The ability to keep your settings every time you open the app. Tired of having to adjust everything very time I want to watch something.
3. When Im watching one of the movies I put on the app, it would be nice to be able to watch from where I left off if I have to stop in the middle and close the app. Also, the movies restart when I get a phone call or I think even when I unplug my headphones while watching.
4. Better YouTube search. The thumbnails are nice but its hard to tell if Im looking at the right video Im searching for. It needs to have the title under the thumbnail and the description when selecting the thumbnail would be nice.
5. Make the play/menu/settings icons invisible when not looking down to select them. Pretty minor but sometimes I notice them while watching something, which can be distracting.
