Tide Tool 2.3
the author of this app says:
Displays tide and current graphs and tables for 6,900 locations worldwide. Displays times of sunrise and sunset, moonrise and moonset, and moon phases. Covers years 1998 to 2031. Provides user-selectable units of height and speed.
It also includes support for expansion memory cards and restores locations in the U.K. A tide level guide, at a level selected by the user, can be displayed on the graph and tide table. Version 2.3 accommodates the 2007 Daylight Savings time changes.
The software and Web site are now offered in French as well as English, and the French tidal coefficient is computed for west coast French ports.
