Good app
Works good. It was my first time to Sundquist and Royal Blue and the app worked good. East of interstate is marked well but app still helped lot. West side not marked and app is necessary. I used it to make it to the eternal flame. I like it. You have to get used to it. I had to turn my phone so that I was pointed the direction I was traveling. It was well worth the money. The other free apps don’t label the trails as well as this app. This review is for Royal Blue and Sundquist app.
