Not OP, but this looks like 3D Relief (requires OpenGL render) + Terrain (Avalanche mode) + Contour Lines + Weather Plug-in. My setup is quite similar, and I also have an optional satellite/aerial imagery layer, a Hiking map style, and quick actions set up to toggle all those on or off when I need to declutter the map. AFAIR all require Premium/Plus to use.
Here’s my profile if you want to quickly set it up in your app: https://share.balsoft.ru/OsmAnd-profile-balsoft.osf
Yep, happy that more and more people recognize it for a treasure of features and customization that it is. For me, it’s the best app for trekking, hiking, and offroading there is, even if we consider proprietary stuff like Fatmap and such.
