Good, useful app
This app is very useful whenever a person needs information about tides. I use it frequently. It is an important aid when sailing the inside passage in SE Alaska.
Suggestion for improvement would be to add a place within the app to report any error.
Also, the Anchor Point tide station in the Wrangell Narrows (south of Petersburg, Alaska) comes up with a label of "Anchor Point, Cook Inlet Alaska" which is another tide station in Alaska but it is hundreds of miles away. The label should be fixed.
