Point at a fish, get an honest answer.
Take a photo of your catch - or pick one from your library - and IDMyFish shows you the most likely species, with how confident it is. It never just declares a verdict: you see up to three possibilities, the features that tell them apart, and an illustration to compare against, so you decide.
WORKS WHERE YOU FISH
Everything runs on your phone. Offshore, on the flats, up a river with no signal - it works exactly the same. Your photos are never uploaded, and the app has no account and no analytics. The free version shows a small banner ad; the one-time unlock removes it.
HONEST, NOT CONFIDENT
Species that look alike are always shown together - gag and black grouper, permit and pompano, blacktip and spinner shark - with the marks that separate them. If the app is not sure, it says so rather than guessing. If several fish are in the photo, you tap the one you mean.
866 SPECIES, WORLDWIDE
Saltwater and freshwater, from the Gulf and the Atlantic coast to the Pacific, Europe and Australia: tunas, snappers, groupers, mackerels, jacks, drums, sharks, bass, trout, salmon, catfish, carp and more.
FULL-COLOUR ILLUSTRATIONS
Over 150 Atlantic and Gulf species carry a Duane Raver Jr. illustration with identification notes: distinguishing features, similar species, where found and typical size. For every other species you get the names, look-alike tips and one-tap links to reference photos online.
ID HISTORY
Keep the fish you confirm - a thumbnail, the species, the date and your own note. Stored only on your phone.
FREE, THEN ONE PURCHASE
Three identifications a day are free, at full quality, forever. A single one-time purchase unlocks unlimited identifications and history, and removes the ads. No subscription - nothing renews, ever.
Identification is assistive, not authoritative. Never eat, handle or make a release decision based on this app alone: a misidentified fish can be dangerous to eat or protected by law. Always check your local regulations.
