Automatic fish measurement
Measure fish with your phone
FishLock uses supported smartphone measurement capabilities to measure a fish without a separate reference object. The system is designed to reliably measure catches to within ±0.25 inches.
The measurement becomes part of the same catch workflow, so you can keep the species, size, photo, location and other details together.
As easy as taking a photo
No separate reference object
Available on supported devices
Private by design

FishLock keeps your catch data on your device. Species, size, notes, locations, tags and other details are not sent to a FishLock cloud account.
There is no account and no subscription. Fish identification runs locally on your phone, so the core app can be used without internet access.
