We ran an informal poll of #OpenStreetMap people on several #Telegram channels to determine their **primary** navigation/mapping app that consumes OSM data. It's very likely that some people are using multiple apps, but the poll only asked them to choose one.
Impossible to mention all apps that but the popular apps were:
* OsmAnd 58% - both official and the #FDroid version
* Maps.Me 35% - including the fork on #FDroid called "Maps"
and a sprinkling of votes for #MagicEarth, #Mapy #LocusMaps
