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.

Ratings and Reviews

Not accurate

Won't load correctly and it's WAY off. Sad when your wind app is spot on but this is junk.

Accurate, User Friendly


UI is easy to use and navigate without any lags. Multitude of data points available-have yet to find an area that is not detected by this app. Excellent support service as well.



If you want a nice graphic tide table for area around you this is nice. The map isn't very useful for selecting distant stations, and you can't specify future dates (like if you're planning a future trip and want to specify August 3rd for example). With some tweaks and perhaps current info this could be a great app.
