Fish identification apps
A fish identification app compares your photo against a trained model and returns the most likely species. CatchVault runs its model on the phone itself, covers 335+ North American freshwater and saltwater species, and works with no cell service.
On-device versus cloud ID
Some apps upload the photo and wait for a server to answer. That fails at exactly the places anglers go: back-country lakes, offshore, deep canyons.
An on-device model answers in seconds without a connection. The trade-off is model size, so coverage is usually focused on the species people actually catch.
Lookalike species
Some pairs trip up people and models alike: white versus black crappie, largemouth versus smallmouth bass, brook versus lake trout, the various sunfish. When the result matters for a size or bag limit, check the distinguishing marks yourself.
From ID to logbook
In CatchVault the identified species fills in the catch record, along with the length, date and place. You confirm or correct it, and the record is saved.
