Ive used this app only once so far (only because I usually know where Im going). And loved that it mapped a route for me using all designated bike paths. Seemed to pick the most efficient - and safe - route. With the exception of some local knowledge assisting in cutting a little distance/time on a couple of turns. Also very helpful that all directions were spoken, as well as showing in sequence on my lock screen for easy reference while riding.
