*2026-07-03, version 3.3.2*

### 5/5 — Best tide app

*2026-07-03, version 3.3.2*

Used it today diving it was very accurate

### 5/5 — So useful and so beautiful — well done!!

*2026-06-27*

I absolutely love the visual representation of the tidal highs and lows plus sunrise and sunset. Moon phases as well! It’s just so very useful if you live near the ocean and are timing your day around making it to the beach. I am at the beach daily for a surf, dog walk, just lounging…knowing the moon phase a tide height helps me understand if I can squeeze in a visit at high tide or not…at sunrise etc. wind and wind direction would be pretty cool too if added.  I use this daily and enjoy the immersive visual aspect of it..

**Developer response:** Thank you for your kind words. Every feedback is important to us and glad to hear that you are finding the app very useful.

$20 a year to have an app pull publicly available info is a scam.

*2026-04-20, version 3.3*

I’m a Fishing Guide so Tides rule my life.   This is by far THE BEST Tide app that I have found.  Very accurate and the visual depiction of the tide, rise and fall, and current place in the schedule are better then any app.
