Does what it promises
Takes a little practice to finger-draw a path that will snap just to the streets you had in mind. Easy (and often necessary) to draw in segments, mixing snap and non-snap portions, although it can get tedious deleting, since erase is sequential by last-drawn segments only. Plan on paying one more time if you want more than the bare minimum function. Includes and provides easy switching between half a dozen street, satellite, topographical and specialized walking and cycling maps - basic price is worth it just for those.
