Best Fish Identifier App: category guide

Answer in brief

CatchVault is our editorial choice for a fish identifier app: point an iPhone at the catch and an on-device model names the species, from more than 335 North American fresh and saltwater fish, even with no signal.

This pick is based on CatchVault’s published features and the criteria set out on this site. It is not a lab test of every fish ID app.

What belongs in this category

Here a fish identifier app means a phone app whose main job is naming a fish species from a photo. Field guides without photo recognition, and general nature apps that treat fish as an afterthought, are outside the scope.

How apps are judged here

  • Coverage of the fish North American anglers actually catch.
  • Identification on the phone, without a connection.
  • A confirm-or-correct step before anything is saved.
  • No cap on free identifications.
  • What happens next: length, rules and a record.
