Bield Fish
Charts, weather, water,
and what your trips show.
NOAA marine charts, USGS lake bathymetry, river gauges, tide and current data — the strongest combined federal-data chart stack in any fishing app. Pattern engines unlock as your trips accumulate. Every synthesized insight shows the catches behind it.

Three commitments
What every Bield Fish feature is held to.
Honest intelligence
Pattern features unlock as your data accumulates. When the data is not there, we say so — no invented confidence, no AI hype.
Maps you actually trust
Federal public-domain data — LiDAR, SSURGO, NOAA, USGS, NHD, NIFC — self-hosted so nothing breaks when a vendor changes pricing.
Privacy you can verify
Your hunts, sits, catches, trips, and harvests stay in your account. Your individual data is never sold, traded, or shared.
The data underneath
Federal charts. Live water. Honest patterns.
Nine public-domain data feeds, self-hosted on Bield infrastructure. The chart stack does not change because a vendor changed pricing.

How it works
Log, build, learn. The same loop, every season.
I
Log
You record what happened. Conditions, wind, baro, time, location, and the result — auto-captured wherever possible. Empty sessions count too.
II
Build
Structure emerges. After a handful of sits or trips, Bield begins to surface the cross-references — what conditions, what places, what time of day actually produced.
III
Learn
Patterns appear. By the second season, the app speaks back: which stand for tonight, which water for this tide, which variety in this frost window. Earned, not invented.
Pattern intelligence
The patterns your water actually rewards.
Every pattern card shows the catches behind it. Tap to see the trips that built the insight.
Tide-stage productivity
2h before high · 38% of catches
Bield maps every catch and empty cast to the exact tide stage that produced it. The patterns travel with your fishery, not someone else’s.
Water-temp correlation
Striper bite · 58–62°F
Lure-by-lure, water-by-water. The temperature window that turned on for you — not the regional average that did not.
Lure productivity
Top jighead: 3/16 chartreuse
Which lure paid off across your sessions, ranked against session count — not raw catch count.
Pressure & front passages
Drop > 0.12 in/24h favors PM
Pre-front bites versus post-front lockouts, mapped against your real history on this water.
Migration calendars
Striper run · arriving in 9 days
Striper, mahi, false-albacore — federal migration data and historical arrival timing, surfaced for your region.
Honest catch ratio
12 catches · 20 sessions
The empty sessions count. Bield never confuses bragging count with catch ratio — the ratio is what makes patterns true.
The product
What Bield Fish actually does.
Eight surfaces, one engine. Built for the angler who logs sessions and the one who shows up to a tournament.
Federal chart stack
NOAA marine charts, USGS lake bathymetry, NHD flowlines, NOAA tide stations — the strongest combined public-domain chart stack in any fishing app.
Auto-captured conditions
Tap once when you launch. Wind, baro, tide stage, water temp, sky, sun position. The friction is gone.
Three environments, equal depth
Freshwater lakes & ponds. Rivers & streams. Inshore & offshore salt. No second-class water.
Sessions, not just catches
Bield logs the empty trips too. Without them, every pattern is a lie. With them, the synthesized insights are honest.
Private waypoints
Your spots stay your spots. Per-waypoint sharing controls — never sold, never traded.
Tournament prep
Pre-trip pattern briefs for a specific water on a specific date. Conditions, tide stage, lure history, ranked spots.
Stocking & migration
Weekly trout stocking schedules from state agencies. NOAA migration timing for striper, mahi, and inshore runs.
iOS, Android, Web
Offline chart tiles so the dock has no signal but the app still works.
What Bield does differently
Three ways Bield Fish is not like the others.
If you have tried a fishing app and bounced off, these are usually why.
Federal-data first
No vendor charts that change pricing. Bield self-hosts NOAA and USGS, so the chart you fish with at launch is the chart you fish with at year five.
Salt and fresh, equal depth
Most fishing apps are bass apps with a salt button. Bield gives offshore, inshore, river, and lake the same engine — not a footnote.
Honest synthesis
Pattern features unlock as your trips accumulate. When the data is not there, we say so. No invented confidence dressed up as personalized.
What's included

Common questions
Frequently asked.
Pulled from real conversations with anglers who tried Bield first. If your question isn't here, write us at hello@bield.app.
No. We offer a 7-day free trial that unlocks the full app — every chart, every engine, every water body. After the trial, the subscription is $12.99/month or $79.99/year for a single app. Bundles are annual only — any two apps for $119.99/year, or all three for $179.99/year. We charge fairly so we don't have to sell ads or your data.
You can cancel any time after the trial. Subscriptions don't auto-renew silently — we send a renewal reminder before each charge. If you cancel within the trial window, you're not billed at all.
No. Your individual catches, sessions, and waypoints never leave your account. Aggregate signals (regional bite reports, hatch confirmations) come only from anglers who explicitly opt in, and the contributing data is anonymized at the collection layer.
All 50 states, plus DC, Alaska, Hawaii, and the major US coastal waters — for charts, NHD hydrography, NOAA marine forecasts, USGS river gauges, lake bathymetry, and tide / flow engines. The roadmap items in the comparison above are honest about what comes after launch.
Federal public-domain data — NOAA marine charts, USGS lake bathymetry, NHD hydrography, USGS river gauges, NOAA tide/current stations, NOAA SST. Processed and self-hosted on our own infrastructure. No commercial chart licensing fees means no watered-down resolution to save money.
Yes. Bield Fish is one app with three environments built to equal depth from day one. Tide engine, flow engine, hatch engine, SST engine — all native, all included.
Yes. Logging, map, tide stage, and pattern engines all work offline. Maps download for the regions you use. NOAA conditions backfill when you return to signal.
Yes. One subscription covers iOS, Android, and web — your phone, tablet, and laptop all sync to the same account.
Each single app — Hunt, Fish, or Farm — is $12.99/month or $79.99/year. Same price for all three. We landed all three at the same rate to keep pricing simple and let you pick by use, not by sticker.
Two bundle options. Any two apps for $119.99/year — you pick which two at checkout (Hunt + Fish, Hunt + Farm, or Fish + Farm). All three apps for $179.99/year. Both bundles are annual only — no monthly bundle rate. That's a 25% discount off two or three singles bought separately at the annual rate.
Bundles make sense if you're using more than one app across the full year — spring spawn, summer growing season, fall hunts, winter scouting. Monthly bundling wouldn't reflect how anyone actually uses these together. If you want monthly billing, subscribe to single apps individually.
The product compounds the longer you use it — your personal hatch calendar gets sharper with every catch logged; tide and flow patterns get more reliable each season. The annual rate is the rate for anglers who plan to stay through a full year of water.
All catches, sessions, and waypoints stay in your account. You keep everything you logged. Pattern engines pause until you resubscribe. Nothing is ever deleted automatically — you can also fully export and delete the account on demand.
Yes. Subscribers can export all catches and sessions as CSV at any time from the Settings screen. Your data belongs to you.
It isn't. Pricing is the same across iOS, Android, and web. iOS and web subscriptions go through our payment provider; Android goes through Google Play. Same price, different rails.
