We took two trips (loop Road to Hana and West Maui Coastline Tour) using the app. We had little difficulty at the very beginning. Once we figured out how to use it, it’s very helpful. We enjoyed all the histories, stories, music, and legends during our driving tours. The GPS offline map was very accurate. We leaned a lot about Maui on the long drive. This app was the best purchase we did for the vacation. We will definitely recommend to our friends who want to explore Maui like travelers rather then vacationers.
