Mapy uses OSM data outside the Czech Republic, and the extra features there compared to FOSS apps are only marginally useful. However, I am in the Czech Republic so I use the year-old 9.55.2 (9550200) Android app (last version before Premium enshittification).
I use Mapy (EU)
Murena Workspace and kDrive instead of Gmail/Gdrive
AlterSend (P2P) instead of DropBox
vgy.me (UK) instead of Google Photos

AI - Andisearch
