Yep it uses a selection of the most important data from OSM because the entire thing would be too huge to keep on your phone. You download the map in sections so region/city based but you can also just get an entire country which will be a few GB.
It can import/export bookmarks and record and import gpx tracks. Has TTS support and you can even edit things (like opening hours and stuff) if you have an OSM account.
