Tide Watch is a harmonic tide prediction application for the iPad, iPhone, and iPod Touch. Tide predictions, as well as sun and moon events, are available for hundreds of locations in the United States, selectable by state or by proximity to the device. Predictions are provided for thousand of specific locations, called “stations”, for which harmonics information is provided by NOAA. Predictions can be displayed as a table or a chart.

Tide Watch predictions do not incorporate the effects of tropical storms, El Niño, seismic events, subsidence, uplift, or changes in global sea level.
