Fish Identifier: CatchScan

Caught a fish and not sure what it is, or whether you can legally keep it? CatchScan tells you both in seconds.

Snap a photo of your catch and get an instant species ID, an honest confidence rating, and the fishing regulations for the water you were actually fishing: size limits, bag limits and seasons, with a keep-or-release badge whenever the rules settle it. No more guessing.

KNOW BEFORE YOU KEEP
CatchScan reads the location saved inside your photo, not wherever your phone happens to be right now. It works out which jurisdiction governs that water, including whether you were in state or federal waters, checked against NOAA boundary data. Then it looks up the rules live from official sources and explains them in plain English.
- Size limits, bag limits and season status at a glance, with the full details a tap away
- Keep-or-release badges, with "Keepable if legal size" when a size limit applies and "Check before keeping" when the rules can't settle it
- Works on photos from earlier trips, so you can identify last weekend's catch from your couch. Rules are dated, with a reminder to confirm your catch date

INSTANT AI IDENTIFICATION
Point the camera, tap, and know. OpenAI GPT reads body shape, fins, markings and coloration to name the species in seconds, using where the photo was taken as a clue to which species live there. It covers saltwater, freshwater, tropical and cold-water fish, adults and juveniles alike.
- A confidence rating on every result, so a firm identification never looks the same as a tentative one
- The field marks behind each call, so you can check the reasoning yourself
- A "Don't confuse with" section naming look-alike species and the one visible feature that separates each
- Catch difficulty, habitat, typical size and conservation status

BUILD YOUR COLLECTION
Every confirmed identification joins your Collection: a lifetime field guide built only from fish you personally landed.
- Cover photo, scientific name and a running catch count for each species
- Milestones unlock at 1, 5, 10, 25 and 50 species

ASK FOLLOW-UP QUESTIONS (PREMIUM)
Unlike simple ID apps, CatchScan chats. Tap a suggested question, like bait tips, or ask your own: whether it is safe to eat, how to tell it from a lookalike, what its conservation status means, or the best way to catch another one.
