Disappointed
Save your money. This app is not intuitive at all for the price. There are better options that are free.
This app is based on raster charts which is fine but when I create a route it should auto download all maps for the route. Instead it expects the user to figure which maps are needed.
This also means that your need connectivity when ever you are planning a route or you will be left without a map. So no route planning while you are at a location without connectivity.
save your money!
