Interestingly, f-droid doesn't initially show CoMaps but does show Organic Maps because apparently CoMaps doesn't pass an antifeature filter for depending on a tethered service on codeberg. I don't quite understand why this is an issue; they both need to download their maps from somewhere, don't they?

Thanks for recommending. I was not aware that a fork of Organic Maps had been created, or that longtime contributors to OM had concerns about the project.
