Great for weather nerds

This is a fun informative app for tracking water monitoring stations. Noah who works Hohonu is a great engineer.

Awesome app

Nice to have weather and tides all in one simple and accurate. Love the app!

Beautiful and functional

It was so cool to be able to look off the pier in town and know that there’s a sensor providing real time data about what’s happening on our own coast.

Better data collection = better results 🙌

As a waterman, many of my daily choices around activities rely on an accurate tidal readings. It’s great to be able to use an app that I can actually trust uses hyper accurate location specific data to inform its tide forecasts. I’ve been often underwhelmed by the many tide apps that pull from the limited geographical readings compiled by NOAA.

Harmonic and subordinate in “harmony” finally

I’ve long used tide apps or a quick google search to look up predictions for subordinate stations. And if a strong nor’easter came through on a high tide and I wanted to view the observed data from a real tide station, I’d have to go to NOAA Tides and Currents. I LOVE that now there’s an app that includes both that I can easily scroll around on a map to compare different stations to each other. Really nailed what I’ve been trying to find for a long time
