AyeTides for the Mac calculates tides and currents predictions on the Mac(™).
Long ago we created the original version of our tide program, Mr. Tides. Over time Mr. Tides became AyeTides for the iPhone and then AyeTides XL for the iPad. Now, we are coming full circle by creating AyeTides for the Mac. It's Mr. Tides, brought up to the latest frameworks and standards, but with even more goodies, like tabbed views and Dark Mode.
We use a tabbed view to show multiple stations, or you can select to have each station in its own window.
