Poor  maybe even dangerous. I've tried to persevere with this app. I checked my usual commute via local cycle path network  and I was unable to understand the description  even though the route was the one I ride. Describes curves as turns  doesn't know where the mini roundabouts are  or where the barriers are  just flummoxed  if live this to be great  but it is simply useless. Not to be trusted I'd say  you were warned!
