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.

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.


Map of locations disappears

The map of the tide stations disappears when the cellular service is out of range. I used the app to travel by boat from the South Puget Sound to the San Juan Islands and when the cellular service was out of range, I would have to guess which tidal station to select.


Network Error scam

Nice app. Worked well for years. Now that have implemented a pop up that claims there is a network arrow and offers a “solution” at your cost. A tide calculator that works in absence of an internet connection. I don’t need the upgrade. Stop lying that that the app is having network problems in an effort to get me to “upgrade”. Booooo! Awful tactic.
