Now available, the #1 US Tide Prediction app has redesigned for iPad with extra features like saved tide tables, calendar date picker, built in map, improved graphics, and more. Tide Graph HD uses the harmonic predictions from thousands of US coastal stations and presents them in a fun and interactive graph. And now, in version 2.0 you also get an intuitive graph that shows sunrise, sunset, moonrise, moonset, and moon phase at a glance. Save recent locations, find locations using GPS location, and save graphs for later. Tides have a great influence on the lives of boaters, fishermen, surfers, coastal communities, marine life, and vacationers just to name a few. Directly or indirectly, the great flow of our massive ocean bodies of water impact the daily lives of everyone on this planet. The cyclical movement of the Earth's tides are caused by a combination of the gravitational forces of the sun and moon as well as the shape of the costal region. Unlike simple tide clocks that you can buy in novelty stores, more accurate tide predictions use special data gathered by instruments located at each tide station. The data from these measurements are used to determine the harmonic components which then feed into the mathematical algorithms which predict tides for the future. The end results are tested for accuracy and adjustments are made as necessary. Tide Graph has US owned Tide Stations Only. An internet connection is required to get the latest tide graph. - See TideGraph.com for a complete list of stations.



  • Bait and switch

    By Whitelabel1972
    After you purchase, the disclaimer says these are not real time and may be completely wrong. Best example of bait and switch ever.
  • Information display bug?

    By Woofman999
    The text in upper right portion of tide graph page partially overlaps so that tide times and moonrise times overlap and are not legible. I have IOS v7. Tried preferences for plain background display - didn't help.
  • No info for Southern California

    By Yo! ed B
    The furthest southern point for information is Newport Beach Ca.!!!! What's up with that?
  • The information you need!

    This app is almost perfect, a great balance of the information you want to see and to have it easily available. My only suggestions might be a favorite section to put your most used stations and a now button. I often scroll or switch to other days so one button to go back to the current date and time would be convenient. Thanks for the great app!
  • The best

    This app is so easy to use. It is accurate for tides and currents. And a whole lot better than the tide apps that cost $.
