Terrible

The dealer was insistent that this app was necessary. After installing I can see the dealer is either A: is clueless of what is necessary (not likely)
B: Trying to drive up numbers for app use (my guess)
Like others have stated their car (in my case a 2016 Forrester) is a great car but the app is a waste of storage space on IPhone absolutely no need.
