RouteDraw

RouteDraw is a utility mobile app suitable for short trip route planning, supporting route drawing, route length/gain/loss calculation, time estimation, GPS positioning, compass, track logging, deviation alert, offline maps, and etc. Of course, the main function is route drawing, you can draw a route along a way easily by moving your finger over the map. RouteDraw should be very useful to you, if you like to plan your route before your trip.
Based on the Mapbox mapping services, the route drawing function should work on all places on the Earth besides the poles. But note that the drawing logic is based on the map display data, which is simplified and does not preserve junction info. Therefore, if you draw while zoomed out, the route will have a higher degree of simplification. And whether two ways are connected is based on estimation, and therefore may not be correct. Also, a map object may show slightly different coordinates at different zoom levels.
