Fish identification that runs on your phone
FishLock does not need to upload a fish photo to a remote server before it can identify the species. The Fishial-based identification model runs on-device, allowing FishLock to identify fish without depending on a network connection.
That matters when you fish where mobile service is weak, unavailable or simply something you do not want to rely on. It also means the identification step does not require your catch image or fishing location to leave your device.

One offline workflow
Identify, measure and log the catch
FishLock brings several common fishing tasks together. By pointing your phone at the catch, FishLock can identify the species, measure the fish, photograph it, map it and log it. The result is a private catch record that does not depend on a cloud account.

Offline also means private
No fishing account to maintain
FishLock does not require an account or subscription. Species, size, notes, locations, tags and other catch details remain on your phone instead of being stored in an online fishing profile.
For anglers who do not want fishing locations and catch history uploaded to a cloud service, that is a core part of the product rather than an optional privacy setting.
