Thanks for the tip about OsmAnd! Google maps is one of the last Google services I use because for some reason Apple Maps doesn’t support directions/navigation in the country I live in even though it has full maps and even traffic. Just installed the iOS app and while it does look like the UI will take a little getting used to, this looks like a solid option!
Oh, on iOS the app is quite different afaik (and, when I last used it, much more limited). I somehow was expecting an Android device, sorry. There may be better options for iOS (though my impression is that most FOSS mobile things happen on Android)
