What's New in Coasti

1.7

October 14, 2026

Coasti is on Apple Watch. The watch app shows your home beach's verdict, the reason behind it, the best window and the beaches nearby, and your home beach comes over from your iPhone on its own. Add Coasti to your watch face: the rectangular and inline complications carry the verdict, and the corner and circular ones show the beach flag with a label you choose, the best window or the water temperature. On watchOS 11 the Smart Stack brings Coasti forward in the morning and when you're near the beach. A swim advisory from the Florida Department of Health now sets the verdict, and the beach page says when the water tested clean again. The new Swim advisories guide explains what the readings mean.

Best Beach App!!

If you’re looking for the best beach app… you’ve found it. This app seems to have the best parts of all the other beach finder apps and rolled it into one!
It’s a key to our vacations in Destin, Venice Beach and Naples.
