Not very useful

We just got back from 2 weeks in Costa Rica. This app was useful on a few occasions but had some serious problems and is not intuitive:
1. Roads and towns in app are like the real thing. They are not well labeled! it was frustrating to be in a small town and have to ask somebody where we were, or try to compare the pattern of roads in the app to a separate map because the towns were not labeled in the app.
2. The app would lock up or crash frequently.
3. Many roads were missing.

This apps is no substitute for a GPS.
