This is a good app
I would like for Lee Ann Rucker to create a subordinate station at 57 degrees, 36.48 minutes, North by 157 degrees, 41.43 minutes, West. That would make me so happy!

The tide data comes from NOAA's National Ocean Service; for more information see https://flaterco.com/xtide/harmonics.html
Very good Xtide implementation
This app ports the functionality of the venerable Xtide program to iOS, adding some nice touches such as location services and good maps. The app meets most of my needs. Getting to the tide predictions for two weeks hence (say) takes a lot of swiping. Linkage of the predictions to a monthly calendar would be very welcome.

The latest version has a date picker - thanks for the suggestion! There's also a list view of the tide data. The Mac version has a basic calendar; I'll see how it works on the iPad. It would be too small on even the largest iPhones.
Slick tide app
Useful at times. Cool plots.
