We got tired of forecasts that didn't know our water.
Bield: Fish started as a frustration shared across freshwater lakes, mountain rivers, and inshore bays — and the same simple question: why doesn't anyone build the tool a serious angler actually needs?
The frustration
We knew our waters. We could tell you which spot to fish on a given morning given the tide, the pressure, the water temperature, the week of the year. Most of that knowledge lived in our heads — and in scattered spreadsheets, log books, and group texts that died every September.
Every fishing app we tried treated us the same as somebody who had never seen our water before — generic regional forecasts, single seasons of memory, tide and flow data that you had to look up in a second app. Our personal data — the only data that actually matters for our specific water — was nowhere.
The insight
The thing we actually needed wasn't a better forecast engine. It was a better recording engine. A tool that could structure the observations we were already making and preserve them across seasons, so that three years in we'd have something a generic algorithm could never give us: a real model of our specific waters.
The decision
We looked for someone building it. We found pin-dropping apps and tide widgets and species ID toys, but nothing that treated the session itself as the unit of data. Nothing that took rivers as seriously as lakes. Nothing that captured tide and flow automatically. Nothing that worked offline well enough to trust on an offshore run with no signal.
So we started building.
The approach — three environments, equal depth
Bield: Fish treats freshwater, rivers, and saltwater with equal depth from day one. It captures empty sessions as first-class data. It pulls tide stage, river flow, and sea surface temperature automatically. It's offline first because the water doesn't have cell service. And it's built to compound — the data you log in year one becomes more valuable in year three and more valuable still in year five.
That's the bet: that serious anglers will do the work of logging, and that we'll build something worth logging into.
Four commitments. No marketing.
Data belongs to the angler
You own it. You can export it. We will never sell it.
Offline first
You are on the water. The app must work without signal. No exceptions.
Three environments, equal depth
Freshwater, rivers, saltwater — built to the same standard. None as an afterthought, ever.
Patterns over predictions
We don't guess where fish will be. We help you learn what your data says about your specific waters.
