About this app

- The best selling iOS Tide App for over 7 years finally comes to Android
- Over 5000 locations in the US
- Includes both modern and legacy locations.
- 1 million tide predictions sent each month

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.

Used to be the BEST! Barely works anymore, 0/10 recommend. Also it downloads the tide info every time you open it so it doesn't work offline. Even if I have the app open, on the screen and navigate away, it loses all info. Very frustrating when tidal predictions for a specific location a year or two into the future are really simple to make. This dataset is not a lot of information and without that info this app is as useful as the free paper books that my dad used as a kid.

Keeps saying an error occured and can't connect to tide graph server. My network connection is fine btw. 5/7 update - only way to get it to work is force stop and reboot phone. Then it only works one time. "Reviews are not a forum for technical issues". Really??? Okay I'm removing this trash app then. The review for this app is ZERO STARS. Bye-bye!....

Moving the map by sliding to the left or right will move the entire application. Huge design flaw. Tide info that I was referencing few hours prior also did not show at all while offline on water.
