Know your fish.
Know if it's a keeper.

Open CatchScan, point the camera at your fish (or pick a photo from your library), and tap. OpenAI GPT reads body shape, fins, markings and coloration, then returns the species name, scientific name, the field marks behind the match and how confident it is — in seconds. It works for saltwater, freshwater, tropical and cold-water fish. Learn more →

Snap a photo of your catch and CatchScan names the species on the spot, then shows a confidence rating so you know how firm the match is. You also get habitat, typical size, the field marks that identify it, and a “Don't confuse with” section naming look-alike species and the one feature that separates each. Learn more →

CatchScan reads the location saved in your photo, matches it to the fishing jurisdiction — including whether you were in state or federal waters, checked against NOAA boundary data — and shows the rules that apply there: minimum size limits, bag limits, open or closed seasons, and a clear keeper-or-release verdict.

Yes, and it still gets the regulations right. CatchScan uses the location stored in the photo itself, not wherever your phone happens to be now, so you can identify last weekend's catch from your couch and still see the rules for the water you were actually fishing.

Yes. Every confirmed identification is added to your Collection — a lifetime field guide of the species you personally caught, each with its cover photo, scientific name and a running catch count. Milestones unlock at 1, 5, 10, 25 and 50 species, so there's always a next one to chase.

Every identification includes the species profile and its conservation status. To go further, tap the suggested question “Is it safe to eat?” and CatchScan explains the species' edibility and what to watch for before it goes in the cooler — follow-up questions are a Premium feature. Learn more →

Yes. CatchScan identifies saltwater game fish and commercial species — from red grouper and cobia to tuna and Chinook salmon — along with tropical reef fish, and pairs each with the saltwater regulations for the water it was caught in. Learn more →

Yes. CatchScan recognises largemouth bass, smallmouth bass, trout, salmon, panfish, catfish and other freshwater species, including tricky juveniles, and explains the field marks behind each identification. Learn more →

Yes. Point the camera at a tank — at home, in a shop or at a public aquarium — and CatchScan identifies the species along with its natural habitat, adult size and conservation status. Care tips, tank-mate compatibility and feeding guidance come from follow-up questions, which are a Premium feature. Learn more →

Every identification, free ones included, has a “Don't confuse with” section that names the species most often mistaken for yours and gives the visible field mark that separates each — a Chinook's black gums and fully spotted tail versus a coho's white gums, for example. With Premium you can also ask “how is this different from a coho?” in the chat. Learn more →

CatchScan is free to download, and you get one full identification every day at no cost — species, confidence rating, field marks, look-alike check and the local regulations all included. Premium lifts the daily limit and unlocks follow-up questions, and starts with a free trial. Requires iOS 17 or later. Download it here →

New identifications need an internet connection, but everything you've already identified — your Collection, species profiles, chats and photos — is stored on your device and can be reviewed offline, even with no signal on the water.
