In BETA 4 and earlier the app was not optimized for high-definition screens. There was also a grey bar at the top of the app that was meant to serve as a place to put the app name, but our design philosophy didn't allow for that. With the new update we have a fix for both of these issues. The grey bar is no longer apart of the app, making for a better viewing experience. With the addition of optimization for high-definition screens you will also notice less blurriness in the text app-wide. We also updated the logos and colors to match our new website design.
The new update is available right now on the Companion App page.
