See Nemo's Eye in Action
Uncover the underwater world in real-time
Know what's happening below the surface.
Know why fish are where they are
Fish finders show you where fish are. Nemo's Eye tells you why they're there — and tips on how to approach. Track fish at different depths alongside the oxygen, temperature, and water conditions driving their behavior. It's the difference between seeing a dot on a screen and understanding what put it there.
See conditions at depth
Most apps estimate conditions from a weather station miles away. Nemo's Eye reads the actual water where your line is — how clear it is, how warm, how deep, and whether conditions are changing.
Get plain-language intelligence
The app translates raw measurements into species-specific recommendations. No science degree needed — just fish smarter.
How It Works
Drop in the sensor
Lower the sensor over the side to your target depth. One hand, one motion — it starts reading the second it hits the water.

Read the water
Your phone connects automatically and shows you what’s happening below — fish depth, water temperature, clarity, oxygen levels, and pressure — updated live, right on your screen.

Fish with intelligence
The app tells you what species are likely active, what to throw, and why. When you catch one, it logs exactly what conditions made it happen — so you can repeat it.
Every session on the water makes the water better.
Every fishing session with Nemo's Eye generates anonymized, GPS-tagged water quality data. That data feeds cooperative partnerships with state agencies, fisheries programs, and conservation organizations — helping monitor and protect the lakes and rivers that matter most. You don't do anything extra. The tool you use to fish smarter simultaneously helps protect the water.
Built in Minnesota. Built for Anglers.

Built on the Water
Nemo's Eye was built by a lifelong angler. From the Lake Minocqua chain to Three Lakes, Eagle River, and the Wisconsin River — all of it shaped a life spent fishing year-round, in open water and on ice, from the time he was old enough to hold a fishing pole.
And for the last 18 years here in Minnesota, that same love of the water and fishing — along with a respect for conservation and a deep curiosity — has been passed down to the next generation.
That experience exposed a clear gap: the technology available to anglers never caught up to the science that already existed. “Data-driven” fishing apps relied on anecdotal inputs dressed up as insight — the predictions didn't hold up. Castable sonar often fell short in basic conditions, whether fishing from shore or trolling from a boat.
Access to public waters is a privilege. From novice to pro, anglers alike know that privilege comes with a responsibility: to be stewards of the lakes, rivers, streams, and ponds we all love.
That's why Nemo's Eye is built with water data monitoring as a primary focus for both recreation and conservation efforts — collecting user-agnostic, detailed water data that can support Wildlife & Natural Resources Departments, National Fish Hatcheries, Water Conservation Groups, and more.
Nemo's Eye is both an angler tool and a water monitoring system — equally by design. It didn't start as one and become the other. It was built to do both, from the beginning.
