Very basic
I was pretty disappointed for a $10 app, and the constant black screen (when going back to the map) is very annoying. I expect to be able to touch trails on the map to get details, not manually scroll through a list. Also the map zoom was very weak. I ended up using the free bike maps (at sports centre) along with sports tracker to map/track my ride.
