## What is FishLock?

FishLock - Cloud-Free Fishing - 100% private, offline app. Works everywhere!

In just seconds, identify a fish species, measure it to an accuracy of ±0.25", snap a photo, and log the catch data into a completely private logbook.

Advanced computer vision for a reliable measurement in real-time, with no reference object needed.  World-class fish species identification (Fishial.ai, developed by the Wye Foundation) adapted to run directly on your own phone, for total privacy.

No subscription and no account! 
No in-app purchases and suitable for all ages!
Keep your fishing data out of the cloud!

FishLock is a standalone, offline tool available as a one-time purchase, and is built to last.  Your data never leaves your phone. FishLock is a fully offline app (an edge-computed, on-device app).

Thank you for supporting an independent app developer.
