They use OSM as source for maps, yes.
Not sure how much they add, aside from offline functionality.
Other apps add extra data sources.
Comment on Apple will reportedly start stuffing ads into the Maps app
T156@lemmy.world 3 weeks agoA little confused, is this basically the same thing as Open Street Maps, just in app form?

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.
