No maps- Just free ads

This app does not show any maps (or indeed anything else except ads). All it does is give me blank screens with ads and options to buy charts or upgrade to the "full" ad-free version. Even after that, you have to pay more since you cant use it until you buy a chart.

I really wanted to check it out to see if its worth buying, but it wont let me. Waste of time.
