One can also utilize features to contribute back to OSM. This includes reporting a bug or adding a POI. This feature doesn't require an internet connection as the points can be uploaded latter upon request.

Through the use of an additional plugin OsmAnd Maps & Navigation is able to utilize contour lines on its maps which helps view the landscape and terrain.

Sometimes one needs more than just navigation, they have a need to view a map or specify a specific route. OsmAnd provides a very nice, detailed map. This can be good for seeing what is around you or showing a place you are talking about to a friend.

It also provides a means to add waypoints on the map which can be used to dictate a specific route (not simple enough to do routinely).

Lane guidance can assist in deciding if one should stay in the right or left lanes. OsmAnd provides detailed information on the number of lanes and which are valid for your chosen destination; based on the data available it may show too many or too few lanes.

Utilizing the community driven OpenStreetMap data has allowed for monthly publishing of new maps that the user can use. Though that doesn't necessarily mean the map data has changed.

OSM provides a map editable by everyone; just like the web-based encyclopedia, Wikipedia.

Using a community edited map allows one to correct isses they encounter. Combined with the monthly turn around, these edits are added for navigation quickly.
