You can enjoy many different types of content with the Goggles:
1. Apps built for Merge VR - which take advantage of the unique inputs. These are identified in VR Start
2. Google Cardboard apps - the inputs use a capacitive-touch, which is compatible with Cardboard v2.0 apps
3. Any videos that are set up for side-by-side viewing on a mobile phone - these may be individual files or apps (e.g., YouTube videos set up for 3D viewing). As long as the videos can be played with an image for each eye ("side by side" format), you can view them in 3D with the Merge VR Goggles
