OsmAnd has plenty of features and offers its full functional in the free version. In addition to that, you can expand your possibilities even further with paid OsmAnd services. Let's take a look at each of them in detail.
OsmAnd+ is a full version of OsmAnd. It provides you with an unlimited number of map downloads, including updates, voice files, etc. Also, this version has Wikipedia feature in it. After downloading the Wikipedia file for your region and enabling Wikipedia in 'Configure map - POI' menu, you'll see Wiki articles attached to objects on the map and will be able to read them in your language. Please note that you can buy OsmAnd+ as a separate app on Google Play or buy it as an in-app purchase from the free version of OsmAnd. In the latter case, you won't have to install OsmAnd+, you'll just have all the features unlocked in your OsmAnd app. Get OsmAnd+
In addition OsmAnd maps, you may want to view contour lines over the main layer of information or even add shading to view the terrain in 3D. To do it, just purchase OsmAnd Contour lines and download the files for your region. You can view hillshade and contour lines separately or add them together to the map.

Liked the contour lines representing terrain? Try sea depth maps to view the contour lines showing the relief of the seabed. To get them, just go to the Download Maps menu and select 'Nautical depth contours'. You'll also be able to download a range of additional maps like the nautical depth points for each hemisphere.

iOS extended features
The purchase system in iOS is a little different from that on Android. The Nautical maps and Contour lines are available for purchase while the Wikipedia plugin is free. The map downloads are available in bundles in case you do not need the maps of the entire world at the moment. For example, you can get the maps of Africa or Europe. Of course, free map downloads are available, as well. To view all the options, please visit the 'Maps & Resources' menu.
