Cool I didn't think it was out for android as well. That means PC/Mac users could run it as well using bluestacks.
Ive been searching for the IOS HD USA version but have come up dry. So I figured that when navionics went to the new country wide distribution that had you download the maps it would prevent sharing thru a authentication method in the store. Maybe sharing of the data cards is possibly then or even modifying the maps off a ios/android app for use in a plotter.
