I've seen several map apps that let you import and export GPX files (e.g. via OneDrive) which are lists of waypoints creating a route. E.g. OutdoorMaps does this for hiking which is really useful. But new routes have to be created externally beforehand, e.g. on PC. I haven't seen any app which allows you to create routes freehand on the phone, but I agree it would be useful and I'd like to know one too :smile:
