The only way to watch YouTube 3D videos on iOS

Im not sure about the other reviewers... I think theyre mis-informed.

This app does what it says it does, plays back 3D videos on YouTube so you can watch them with 3D glasses. With the regular YouTube app, these videos will appear normally as two side-by-side images. This app will mix them for whatever type of glasses you have, and gives you some additional adjustments to fine tune for your liking.
