Feeling ripped
Youve got to use a newspaper or other means of finding out local tide information and plug it in to the iPhone before it even begins to work. Youve got to do this for every different area you visit. The app makers, purposely I surmise, do not make this clear before you part with your money. One of the first points made in their help menu is that the product is sold as is. In other words dont try to get your money back. As is doesnt cut it. Consider yourself warned.
