CatchRules - Fish ID & Rules

LiDAR Measure, Tides & Reg

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Identify ~1,500 fish species, measure them with LiDAR, and look up fishing regulations for every U.S. state and Canadian province. Built for recreational anglers. CatchRules is a compact iPhone reference tool that combines the three things anglers actually need on the water — a fish identifier, a measuring tool, and a jurisdiction-aware rules lookup — with tides and a catch log on top. IDENTIFY ANY FISH, OFFLINE Photograph your catch and CatchRules names the species in about a second. The on-device AI classifier recognizes 1,494 fish species, from largemouth bass and rainbow trout to halibut, red drum, Chinook salmon, and hundreds more. No internet, no cloud upload, no account. Works at the dock, on the boat, or deep in the backcountry. MEASURE WITH LiDAR Tap the fish's head. Tap its tail. LiDAR-equipped iPhones (Pro models, iPhone 12 Pro and newer) read the length in seconds, accurate to the centimeter in good light. No ruler, no tape, no guesswork. Reference only — always confirm legal size with a physical ruler before keeping a catch. RULES FOR EVERY STATE AND PROVINCE 65 jurisdictions in total: • All 50 U.S. states • All 10 Canadian provinces • 3 Canadian territories (Yukon, Northwest Territories, Nunavut) • U.S. federal waters (NOAA) • Canadian federal waters (DFO) Look up size limits, daily bag limits, possession limits, open seasons, and slot rules for thousands of species. Downloaded regulations stay available offline. No signal, no problem. TIDES & CURRENTS NOAA and CHS tide predictions for coastal fishing stations across North America. Today's highs and lows, a full 12-hour curve, and upcoming events at your nearest station. Plan your trip around the bite. LOG EVERY CATCH Every identification lands in your personal collection. Build a visual log of every species you've photographed, with dates, locations, and measured lengths. Track milestones; revisit every trip.
