Fish Identifier: CatchScan
ID Your Catch, Check the Rules
Free · In-App Purchases
Snap a photo, ID your catch instantly, and check local fishing regulations — size limits, bag limits & seasons. Know before you keep. Never risk a fine.
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, seasons, and a clear keeper-or-release verdict. No more guessing. No more risking a fine.
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 and looks up the regulations that apply there. In United States waters it also checks NOAA boundary data to tell state waters from federal.
- Minimum size limits for your species and region
- Bag limits so you stay within the law
- Season status, open or closed
- Clear keeper or release guidance
- Works on photos from earlier trips, so you can identify last weekend's catch from your couch and still get the right rules
INSTANT AI IDENTIFICATION
Point the camera, tap, and know. OpenAI GPT reads body shape, fins, markings and colouration to name the species in seconds, across 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

FinScan is now CatchScan. Same app, clearer name.
YOUR SPECIES COLLECTION
Every confirmed catch now joins a lifetime field guide built only from fish you have landed, with a cover photo, scientific name and running catch count for each species. Milestones unlock at 1, 5, 10, 25 and 50 species, and records survive even after you clear old chats.
MORE HONEST IDENTIFICATION
- Every result now carries a confidence rating, so a firm match no longer looks the same as a tentative one
- A new "Don't confuse with" section names the species most often mistaken for yours, and the single visible feature that tells them apart
- The species card has been redesigned around a cleaner field-guide layout, with a clearer catch-difficulty gauge
REGULATIONS FROM WHERE YOU ACTUALLY FISHED
CatchScan now reads the location saved inside your photo rather than wherever your phone is at the time, then matches it to the jurisdiction that governs that water, including state versus federal waters checked against NOAA boundary data. Identify a photo from last weekend's trip and you still get the right rules.
POLISH
- New motion design and haptic feedback throughout, with full Reduce Motion support
- Redesigned share cards for showing off a catch
