What's New

Updated a few tide predictions and fixed "upgrade" link.

App Description

World Tides 2015 provides tide predictions for 2015 by using the Simply Harmonic Formula and harmonic constants provided by the UKHO to give 7 day tide predictions without the need for an internet connection. Not all countries are supported because of licensing issues. Please see below.

Unlike real time data, tide prediction software is based on historical measurements taken at various locations. It does not use current weather conditions or take into account any geological changes. Accuracy varies by location resulting in time and height shifts. This software is not intended to replace navigational equipment and should not be used where danger or harm could occur. Professional navigational software costs around 100 times as much as this app. Use this app only at your own risk.

Contains nearly 3500 ports from many countries around the world. Please see the list of supported countries below.

Features: Moon/Sun Rise/Set times, large slidable zoomable tide graph, recent locations, built in zoomable map, search, details page, and manual time offset override option.

Supported Locations
England, United States, Ireland, Australia, New Zealand, United States, Germany, Belgium, Netherlands, Portugal, Japan, Malaysia, and much of South Africa, Central America, South America, and the Pacific Islands.

Unsupported Locations
Canada, France, Hong Kong, and many other countries are NOT included. Please see the list of ports at http://www.brainware.net/apps-world-tides-map to see if your area is supported prior to purchasing the application.
