There is a GPS support and a rudimentary navigation, which unfortunately only by car to work (or I have the menu item is not found for the conversion). However, we have always had an overview in a big city abroad, where we are and where we are moving towards. Here even the smallest footpaths are registered, which are not even detectable in other Card Apps * cough * * cough * Google Maps
Speaking of other countries: The card saves locally to have a plethora of information contingent and nervous after the image again need hours to reload - or in the middle of nowhere not even invites to GPRS level. After all, the locally stored data are of course immediately available. This suggests, of course, in the file size to Beech, but with today's storage in the phone / tablet which should be no problem. Single tickets can be downloaded on request and also delete them.
A big advantage over Google Maps are definitely the categorizations. Hunger, but the restaurant is too expensive? Just search for the nearest object, which is categorized as a supermarket. On A ... the world and tired? Show me hotels near. There are marked at their respective positions in the zoo park benches and even the animals. Children whine? No problem, the next playground is ... Located at 334m.
Why is not there the already on Google Maps? There, still in its infancy. For this there is the navigation relatively good, but consumes very much data volume.
The categorization is indeed a feature of OSM and not this app, but it is in extremely well encapsulated and is very easy to operate even for the layman. Therefore 5 stars.
