It's pretty nice and what I use because all the other apps like Gaia and Wikiloc are so extremely commercialised. When I tried both of them out, neither had a way to pay without having an android with a google account which I don't (I use degoogled android). And GaiaGPS was taken over by some other company that started monetising it more.
I don't mind paying for an app, I paid for some others outside of the Google store (nine folders and cryptomator) but many don't bother to offer this option.
But I don't think OsmAnd is great for viewing elevation profiles of routes. It makes a little elevation graph below the calculated route, but it's really hard to see where this maps out to hard parts on the actual map.
For mapping out the hard parts, there's a separate "plugin" that you can enable to turn on contour lines and hill shading or slope map an overlay on the main map https://osmand.net/docs/user/plugins/contour-lines
I know! And I use it. But it's not super visible. I'd love to see colour shading on the route lines based on the gradient or something. OSMAnd does know the gradient, it just doesn't show it in the map view.
