PNW Fishing Atlas

PNW Fishing Atlas is the private fishing intelligence app for serious Pacific Northwest anglers.

Log every trip in under 90 seconds — one photo, and the app auto-fills tide, wind, pressure, water temp, swell, moon phase, and 15+ environmental conditions. Your catch history stays on your phone. Always.

PREDICT YOUR BEST DAYS Open the app to a 14-day fishing forecast. Five XGBoost machine learning models — trained on 13 years of Washington State creel survey data — score every day for chinook, coho, lingcod, halibut, and pink salmon across all Puget Sound marine areas. See which days look great and which to skip, with plain-English explanations like "Falling pressure — active bite expected" and "Full moon — prime time for lingcod."

Tap any day to see the full breakdown: catch probability by species, by area, with the conditions that matter most for each fish. The app tells you WHERE to go, WHEN to go, and WHY.

TIDES + ENVIRONMENTAL TIMELINE A beautiful tide chart with butter-smooth curves (240 data points per day from NOAA). But it's more than tides — stacked below is a full environmental timeline: wind speed with go/no-go color coding, barometric pressure with trend arrows, cloud cover, and temperature. All on one synchronized 24-hour timeline. Swipe between days, tap the date to jump to any day on a calendar, and switch areas instantly.

INTELLIGENT CATCH LOGGING

• One-tap camera capture with automatic GPS and timestamp
• Auto-fetched conditions: tide, wind, pressure, water temp, swell, moon phase, solunar periods
• Species picker with counts, kept/released toggle, and weight tracking
• Depth slider with quick-pick buttons
• Lure/bait autocomplete from your history
• Log skunked trips too — the AI learns from unsuccessful conditions

YOUR HISTORY, YOUR WAY Browse catches as a list or map. Filter by species, location, or date range. Search by keyword. Tap clusters on the map to see all catches in an area. Every trip shows full conditions in a detailed card — your own fishing journal with perfect recall.

PREDICTIONS THAT LEARN New to the app? You get useful predictions immediately from regional fishing data. As you log trips, the model blends your personal patterns with the baseline. After 15 trips, predictions are fully personalized to YOUR fishing style.

The predictor explains itself: top 3 factors affecting your catch probability, best time window, conditional statements ("if wind drops below 10kt, this jumps to 45%"), and depth recommendations from your history.

PRIVACY FIRST No accounts. No server. No data collection. Your catches, photos, GPS coordinates, and fishing history never leave your device. The only network calls are to public weather services (NOAA, METAR, Open-Meteo) to fetch conditions. Backup and restore via encrypted local files.
