Fish Identifier: CatchScan
ID by Picture, Check the Rules
Free · In‑App Purchases
Snap your catch for an instant species ID and the local rules in plain English: size limits, bag limits and seasons, from official sources. Know before you keep.
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.

Ratings & Reviews
Our biggest fishing-rules update yet: clearer answers on what you can keep, in plain English.
- A redesigned regulations panel: size, bag and season limits at a glance, with the full details a tap away.
- Plain-English rules that name the waters and the authority in charge, with no jargon.
- Smarter badges: "Keepable if legal size" when the rules set a size limit, and "Check before keeping" when they can't settle it. Badge text is easier to read, too.
- Every result shows the date the rules were checked for, with a reminder to confirm your catch date before you keep a fish.
- If a scan has no location, the result now explains why local rules weren't checked, with a shortcut to turn location on when it's off.
- New suggested questions after each identification, including bait tips.
- A refreshed welcome tour asks where you usually fish and fits every screen and text size, from iPhone SE to the largest accessibility sizes.
- Accessibility: VoiceOver and Voice Control now label every control in the main screens, with improved Reduce Motion and Increase Contrast support.
- Privacy: your photo's location now goes to NOAA's US boundary service only when it's in or near US waters.
