ExpB is pretty good. It does not work particularly well on mobile. (Does anything?) One thing that would make it better would be the ability to change the pixel width threshold breaks between desktop, tablet, and mobile. A primary concern is that many phone users (especially when using map apps) have a tendency to turn the phone sideways. This results in ExpB trying to jam the tablet version onto the phone rendering the app a useless mess. Adding a setting to control the width breaks would be good. Or the hardcoding could be changed to a more generous pixel width that is wider than length of most phone screens.
