Detailing the differences between the Mobile XReach and the RealWear XReach apps.
In a nutshell, XReach on RealWear does not support annotating, chatting during a call, flipping the camera during a call, or changing your language. Some of these are complex to pull off using the RealWear Glasses human interface but we're constantly working with RealWear to improve the experience and add new features.
