While I like to cycle, I also like to go places. Where I live, some places are just too far to get to by bike (I don't have a shower at work and 70km one way is a decent ride).
To me a car provides a considerable amount of freedom. A bike provides me a different kind of freedom.
Locus maps seemed interesting to me. I was surprised it was not available on F-droid. I found it on the Aurora store though. Contains ads and 4 trackers (google and facebook). Google play services is a dependency.
I'll stick with osmand.
