The more you use it the more you will like it. One point; its important to download AC to the iPad so that you have it offline. But AFAIK it does not automatically update that downloaded content. Ever so often (monthly) "log out" of AC (you may have to "log in" and then "Log out") and accept the offer to delete AC content to save space. Log back in and re-download the content to get the updated date. Seems cumbersome but I may have missed an easier way.

The owners of Ac (Karen & Jeffrey Siegel) are active cruisers and seem to be genuinely good people. AC itself is a game changer and you quickly learn to read between the lines of the reviews and work out who to believe.
