Hey there, It would be really amazing if you add a different option of interfaces in companion app. For example, when I am riding free ride it would be preferred for me to see my training zones and at what grade I climb rather than a map. My monitor is not so close so see it on mobile would be much easier. Furthermore sometimes I dont need to see the track aswell.. just stats, kilometers, climbed meters, watts zones etc. 
Thank you very much!
