From Hahn Software Development:
For the iPad, check out AyeTides XL!AyeTides displays tides and currents (also known as tidal streams) for nearly 10,000 tide or current stations worldwide (currents only available in North America). It does not require the Internet; all the stations are available at a moment's notice.Choose a station alphabetically, geographically, or near your location. Set up your favorite stations, or pick a recently opened station. See the value now and the day's tides in a summary table, or by rotating the iPhone/iPod Touch, as a graph. Move from day to day by swiping left or right. Find out sun and moon times via the Information view. Jump over to Maps to see where the station is located.AyeTides automatically compensates for the station's local time, and for Daylight Savings (Summer) Time.
What's new in this version:
Fixed a crash when trying to move from the station's miniature map to the full-screen map.
