Why does F-Droid tell me that the app has features that I may not like?
Non-Free Network Services
This Anti-Feature is applied to apps that promote or depend entirely on a Non-Free network service, or any service which is impossible, or not easy to replace. Replacement requires changes to the app or service. This antifeature would not apply, if there is a simple configuration option that allows pointing the app to a running instance of an alternative, publicly available, self-hostable, free software server solution.
Because you can't change it from using OpenStreetMap.org to an alternative self hosted site.
Because it tracks real time location and uses the internet. Unless it's an app like this where you explicitly want that functionality, that's usually a sign of some sort of tracking mechanism for advertising or nefarious purposes.
That just is not what F-Droid is saying. Why would you even claim that?
This is a cool idea! I contribute little by little when I can but this app looks like it makes it more convenient to do so.
