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.

- simplified the selection of custom date ranges
- chart views are not strictly bound by date range
- fixed a particularly egregious bug where the first selection of a location after loading the app could display predictions for the wrong location (i.e., incorrect results); not a way to make a good first impression
- fixed another bug in the station list where conditions and predictions for the wrong location was sometimes displayed in a list entry
- updated harmonics file from which predictions are generated, although this should not make a significant difference in prediction values
- removed obsolete Apple Watch support (SDK v1); planning to restore this with better features in a future release
- various other minor bug fixes and performance tweaks
