The app works great for its intended purpose but it has a flaw that ruins it. For some reason they placed a very light colored link that easily blends into the background to something called openstreet. It is placed right in the middle lower section so almost every time you try to scroll your map, the link will get activated and it takes you to this website and away from your map. It is very worrisome if you are tracking your way points through a tough channel and suddenly your map is gone. I have the paid version of navionics too. If they could get rid of that stupid link it could be a great app.
