- Provided over 10 billion predictions - Supports iOS 11+, Watch OS 4.3+, iPhone 7+ Tide Graph 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.
Great App- definitely worth $0.99
I have bought this for $0.99 for the past several years. It’s one of the few apps that I’m willing to shell out money for. I’m a boater and live in South Florida and knowing the tides around here is important. It’s a great app, easy to use and displays the information is several different formats. I am pleased with it and will continue to buy it every year.
Gotta have it.
When I fish off the Oregon coast, knowing tides is important… It impacts my fishing, when I can cross the bar, and when does stay home. I paid the nominal fee for the premium so that I can plan my fishing trip to weeks or even months in advance.

New review
I don’t see a way to update a review or change it or delete it. I had an issue, couldn’t solve it, wrote a crummy review in frustration. I finally contacted them and after many emails back and forth we were able to resolve the issue, which was “user issue” not the app. So 5 stars for a great app and 5 stars for customer service and if there’s a way to delete it let me know.
Garbage
I don’t understand. I have this app on both my iPhone and my iPad. My iPad is accurate. My phone will show a 5.6 tide when it’s a negative tide. I have deleted numerous times and downloaded again. Makes no difference. I have written a review no response. I have tried to contact support no response. They both have the same exact settings. I have checked it. I have others check it and everything is the same yet. my phone is always off showing the wrong tide.
Always wrong
I have this app on both my phone and iPad. They are identical. The app on my phone is often incorrect. For example, my iPad will show a zero tide at the same time that my phone shows 4 1/2. I have deleted the app on my phone several times and reinstalled, and it will show the correct tide for a few days and then it’s off again. If anyone can tell me how to correct this, I would appreciate it. I took a screenshot of both the iPad and the phone today and everything is the same the date the time, but the graphs are way different.
Won’t upgrade
Have used this app for a few years s now but there is no way to use in new iPhone. 14. It would not accept my restore option and does not upgrade either. Too bad. Was good now not so much.
