AyeTides displays tides and currents for over 9,300 stations worldwide. 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 current value and the day’s tides in a summary 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.
