IDMyFish: Offline Fish ID
by Verona Solutions

Point at a fish,
get an honest answer.

Take a photo of your catch and IDMyFish shows the most likely species, how confident it is, and the marks that separate it from its look-alikes — so you decide. Everything runs on the phone: offshore, on the flats, up a river with no signal.

Three free IDs a day, forever — one purchase for unlimited, never a subscription
866 species Never online No account, no ads
Possible matches for a photographed fish: Red Drum as a 99% likely match, with Black Drum flagged as commonly confused

What’s included

Honest, not confident

If the app is not sure, it says so rather than guessing.

  • 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.
  • Up to three possibilities — each with its confidence, never a single verdict. If several fish are in the photo, you tap the one you mean.
  • Look-alikes shown together — gag and black grouper, permit and pompano, blacktip and spinner shark — with the marks that separate them.
  • Full-colour illustrations — nearly 200 Atlantic and Gulf species carry a Duane Raver Jr. illustration with distinguishing features, similar species, where found and typical size.
  • Reference links — one tap to iNaturalist, Wikipedia or FishBase for any species, when you do have a connection.
  • Works where you fish — recognition runs on the phone, so it behaves exactly the same with the radio off.
  • Private by construction — photos are never uploaded; no account, no ads, no analytics.
  • 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 IDs and history. Nothing renews, ever.
Assistive, not authoritative. IDMyFish suggests possible matches, and it can be wrong. 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. Recognition models by Fishial.ai (MIT license); illustrations by Duane Raver Jr., used under license.

Know what you caught before you decide.
