iPad Screenshots


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.

Works perfectly

I've tried all the tide apps on both the iPad and iPhone and I must say that this is the very best one out there. They also have an iPhone version which is the top tide app for iPhone. With nearly all 5 star ratings, I can understand why. But this iPad version is even better. The data is very well organized and easy to read. I wrote the developer and asked them to add a large moon picture on the iPhone version so I could get rid of my moon software. They didn't. But they did add it to the iPad version. I guess they didn't have room on the iPhone. Makes sense now. I also like the built in map that shows the tide location. This is better than the iphone version which makes you leave the app to see the station on the map. Lastly, this has a +/- week button which lets me skip ahead instead of having to hit the + day button a million times. I've told my friends and they are all getting this app. I wish all apps worked this well and were designed so perfectly. Kudos to the developer! Keep up the good work!

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!

Decent, but one serious flaw

Still one huge flaw, which tells me they do not understand tides. The range of the charts resets as the range of the tides changes, this masks highs and lows. It must not reset!!!!

On the annoying side finding the location I want is a huge hassle, naming is not consistent. It should be by body of water then name, or by county then by name. Now it is all over the map, or it goes by closest location then next and so on. That may work in a moving boat but not from home, where I use this to plan.

Also sometimes the bottom half of the graph is cut off and you have to turn the iPad 180 degrees to get it to reset.

The serious fault is the graph does not use a constant zero point. Minus tides can be graphed the same as 1 foot tides, they reset the zero point to the lowest tide of the day. You never know by looking without checking the scale. The nicest thing I can say about that it is stupid. It is very misleading and dangerous.
