World Tides uses 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.

Supports AppleWatch 2.0 App, Complications, TimeTravel, Glances

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.
