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.

I’ve used this app for several years now.
For $0.99 per year, it’s the best tide map on the market. Easy to use and set up. Information is accurate and the graphic display is easy to understand. I highly recommend this app!

Great Tool

I have been using this app for many years.
It’s convenient and easy to see graphical depiction of what the tide level is and what it is going to be any time during the day.

I surf everyday and this app is a real help in deciding where and when to go surf at the tide dependent areas near me.

Easy, does what I need it to do

I use this to know when the best time is to launch my fishing kayak from my local beach. Simple and easy. Ignore the 1 star whiner from May 26th. If you want the data when you don't have internet, it's a small fee for the more than casual fisherman.
