Apps for offline navigation and editing

is there an android app that allows me to view, navigate and edit the map offline. Preferably a FOSS app. Thanks!

Vespucci: for a full editing experience but no navigation.
OsmAnd ( for a full navigation (and a lot more) experience but limited editing.

I don’t think vespucci can show the map offline.

Depending on what you call “the map” sure it can, see for using OSM data offline. If you want to use a background layer offline you can do that too with the MBTiles support.
