I've been using on this trip to Norway and the detail is excellent. (That said, the only place I found, including undersea tunnels, that I didn't get signal was in the lower car hold of the ferry. This place has infrastructure.) I use it back home to label businesses and add other points to the map. Organic Maps uses OSM data offline and is a little friendlier.
