I use Oruxmaps (Android 7/ Samsung J5) on my bike.
I'm missing following feature (I heard OSMAND has a feature like this, but I never tried the OSMAND-app):
After loading a track and say to Orux "follow them" I turn the screen off and every 20m (maybe 10m or 30m) before I have to turn the screen turns on and show me the direction or maybe the map.
All I currently have is, when I forget to turn, Orux tells me that I'm wrong. But it would be better Orux tells me in advance when I have to leave the way/ street ....
Sincerly
