Our story
Born on the Water, Built for Anglers
FishProof started with a simple frustration: leaving the scale or measuring tape at home. We were tired of guessing weights, arguing over who caught the bigger fish, and missing out on accurate records of our best catches.
So we built the tool we wished existed. Using cutting-edge artificial intelligence driven computer vision and a dataset of thousands of fish images with verified weights, FishProof delivers reliable weight estimates from a single photograph. No handheld scale. No tape measure. Just your phone and your catch.
Whether you're a weekend warrior on the kayak, a tournament competitor tracking your personal bests, or a catch-and-release conservationist who wants to minimize handling time — FishProof gives you the proof without the hassle.

From the field
Verified by Real Anglers
"I've been fishing for 30 years and this is the first tech tool that actually feels useful on the water. Verified my 8-pounder within 3 ounces of the certified scale. Now I share every catch with my buddies before I even leave the dock."
Mike Thornton
Tournament Angler, Texas
"As a catch-and-release guide, I love that I can verify a client's trophy without stressing the fish. Snap a photo, get the weight, release the fish. The client gets proof of their personal best and the fish swims away healthy."
Sarah Chen
Fly Fishing Guide, Montana
"My kids love using it. Every fish we catch becomes a mini competition — they race to photograph it and see who caught the heaviest one. Then they share the results with their cousins. Great family tool."
James Okafor
