Three weeks and 600 nautical miles of sailing between the mainland and the Balearic Islands have allowed me to test in live some of iPad maritime applications we have.
Warning : There is no question of making a point-by-point comparison between applications, but rather to highlight certain essential aspects of their use. On the other hand, applications used were up-to-date at the beginning of July. Developments are rapid, and updates may have occurred in August or early September that I did not have. Finally, the messaging app iNavX associated with Navionics charting available from the X-Traverse server for me is the "master-standard" marine applications. iNavX is the most complete application in terms of features to date, and Navionics charting (from the X-Traverse server, I specify) closest to the geographical reality observed by many users.
