VR ONE AR is a free multimedia Android app developed by Carl Zeiss. The app is designed to be used with the ZEISS VR ONE headset and a paper cube that comes with it. Each side of the paper cube has a different background image, and the app can detect which image is in front of the camera and project a corresponding 3D model onto it.

This fun and interactive app provides an immersive AR experience for users. By using the foldable box template provided on the developer's website, users can easily create their own paper cube and start exploring the virtual world with the ZEISS VR ONE headset.

However, it is important to note that the app may take up to 15 seconds to load the live camera view in VR mode. If you encounter a black screen, simply close the app and restart VR ONE AR. Overall, VR ONE AR is a great addition to the ZEISS VR ONE ecosystem and offers an exciting way to experience augmented reality.
