The app is ok but it does not provide anything that you couldnt get with google maps and a guide book on beaches. the most useful part of the guide is the beach breakdown, as it points out better places for leaning to snorkel, snorkeling and places where you shouldnt swim. The app is full of useless information that is somewhat randomly organized. I also believe that some of the so-called shopping complexes may have paid for advertising, as only certain ones are mentioned (without any distinguishing reasons). Finally, the app does not make use of the GPS feature, as it does not provide any helpful directions or parking suggestions.
