Quick update on Cartes: They now support English. It looks like the most common stuff has been translated, but there’s still a little work to go.

I’ve used OsmAnd+, Organic Maps, CoMaps, MapComplete, etc.
My favorite app that I’m looking forward to is CartesApp. Unfortunately it doesn’t have an English translation yet. It’s only geared towards French users for now.

It has an interface that’s very familiar to Google Map users, and clicking on locations brings up the kind of information you’re used to when using Google Maps.

Edit: That being said, the web app works fine for me when “installing” with a browser that has a built-in translation service.
