[Edit: To answer my own question a little bit, I found a post from September 2025 that compares OsmAnd and Organic Maps (which this project forked from): https://blog.firedrake.org/archive/2025/09/OSMAnd_vs_Organic... .
I can't find anything more recent or for CoMaps specifically, other than auto-created "alternatives" pages. I would absolutely love to hear from anybody who has tried both!]
