Mobile App for Fishing

A fishing app is an intersection of several technical domains: offline maps (angler on waterway often no signal), bite forecast (weather + lunar calendar + barometer), catch log with geolocation, and social community. Making it all work organically is a non-trivial task.

Offline Maps of Waterways

App foundation — map with waterways, fishing spots, working offline.

Tiled maps for offline: MBTiles format (SQLite with tiles inside). User downloads selected region map in advance. iOS: Mapbox Maps SDK perfectly supports offline via OfflineManager.downloadStylePack + TilesetDescriptor. Android: similar via Mapbox or OSMDroid with tile cache.

Budget alternative — OpenStreetMap tiles + Leaflet/MapLibre in WebView. Native loss noticeable, especially working with GPS track.

Fishing spots — user POI (fishing_spots): coordinates, name, water type (river/lake/reservoir/sea), preferred tackle. Stored in cloud, sync to SQLite for offline.

Vector layers over map (spawning zones, forbidden areas) — GeoJSON from server, renders as MGLFillLayer (Mapbox iOS) or PolygonOverlay (MapKit).

Bite Forecast

Fish activity prediction — combination of factors:

  • Atmospheric pressure (trend: rising/falling/stable). Stable high — good. Sharp drop — bad. Data: OpenWeatherMap or Open-Meteo (surface_pressure).
  • Moon phase. Full and new moon traditionally considered active. Calculate locally via formula (no API): moon position computed from date offline.
  • Water temperature. OpenWeatherMap water_temperature for seas; rivers/lakes — UserReport (anglers input themselves).
  • Time of day: morning dawn (30 min before/after sunrise) and evening — peak activity for most species.
  • Wind: moderate west — good, strong north — bad.

Forecast algorithm — weighted sum of factors → rating 1-5 "fish". Specific weights picked empirically or via ML model trained on catch diary data.

Catch Log

Record: fish species (select from reference + photo for ID), weight/length, tackle, bait, depth, spot coordinates, weather at catch time (auto from API). Fish photo — auto-measurement via AR (RealityKit ARWorldTrackingConfiguration + MLModel for size estimate from reference object).

Fish species ID from photo — CoreML model (trained on iNaturalist dataset) for iOS, ML Kit Custom Model for Android. Accuracy 70-80% for common species — sufficient for form pre-fill, user corrects.

Season stats: best spots on heatmap, top species, comparison to last year. Swift Charts (iOS 16+) or MPAndroidChart for graphs.

Community

Public catch feed — users share results (option to hide exact coordinate — "water without point"). Angler rating by catch weight. Forum by waterway — geolocation-attached discussions.

Point confidentiality: "secret place" — coordinate stored with ±500m radius noise on publish. Real coordinate stays in personal diary.

Timeline

Basic app (offline map, catch log, bite forecast) — 6-10 weeks. Full version with fish ID via ML, AR measurement, and community — 4-6 months. Cost individual.
