My Garmin Edge has turn by turn navigation but you need to be looking at the screen. Not always easy in bright sun and traffic. I looked at several voice nav apps and Komoot is easily the best. The planning method is weird until you figure out the waypoints can be resequenced (duh). If you miss a turn, the app INSISTS on routing you to any missed waypoint until you reach another waypoint, and it resumes without comment. My takeaway from that is to not place waypoints in areas you might be freelancing. The funky rerouting and the lack of GPX import are my only complaints. Fine, fine app.
Hurri47 about komoot - hike, bike & run, v8.4.1
