WorldTides provides one year of tide predictions for 8061 locations from every costal country in the world! You can choose any date in the year you like. In addition there are 715 more locations which provide 7-day predictions (today + 6 more days). And best of all, you don't need to be connected to the internet because everything is built-in including the map. However, for completeness, the app also provides another 277 web links to locations which we could not embed in the app.
