Great design

Clear, clean, and intuitive to use with a solid amount of functionality. Way better than any other tide app I’ve used for both casual beach walking and multiple night backpacks past pinch points :)

Great App

Simple and very easy to use

I love this app

It’s kept me in the know for a long time now! Very helpful

A Rare Unicorn

No in-app purchases. No subscriptions. No data collection. No ads. Clear, concise, and useful presentation of data. I practically did a double-take when I ran across this app store listing.

This app is a rare unicorn. A vestige of the App Store that was. All apps should be this good and respectful of their user base. Cherish it and hope that the developer never changes their tact.
