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.

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 perfect tide app

I saw the screen shot and knew I had to have this. What I didn't realize is how well it would work! The large tide graph in horizontal mode is fantastic. I can move the bubble and get the exact time of any tide level. I need this because I have to watch out for tides below 3' in the canals where I live or I could get stuck. And that would be very embarrassing for me when I have a bunch of friends on my boat :-)

An especially nice feature is the new date picker and how it shows which dates I have loaded graphs for. This assures me that I can view these graphs later when I no longer have a wi-fi connection. Of course, all you lucky guys that have the new 3G iPad don't have to worry about this. But, I like my wi-fi only version just fine :-P

This is by far the best tide app I've ever seen anywhere on any device. The graphics and functionality are a perfect example of how apps should be written to take advantage of the amazing iPad. Definitely raises the bar!
