New to fishing - lifesaver!

As a single mum to a young keen fishing boy, this app has helped me so much!

Southern Smiler

I’ve had this app for a number of years- it’s incredibly useful . I do citizen science in shellfish reef restoration and am also a recreational fisherman, but not an ichthyologist. It’s helped out a lot, enabled me to identify & catch or release many fish. Photo function is great . Even in FB chats, I scroll through the hur-hur yokel’s ‘humour’ or the trolling to look for Kristiian’s reply on ‘how to identify ‘ - clear, accurate, helpful. A Southern Smiler is the most recent fish saved to the brine . Subscribe, it’s worth it.

App not working anymore

I’ve been using this app since Jan without any issues, but have recently been logged out for some reason (maybe an app update?).
I cannot log back in- every time I enter name and password the app glitches and closes. So disappointed, I loved this app!

FAQ

What does the iDfish app do?

iDfish uses advanced on-device AI to instantly identify fish species from a photo, even when offline. It also provides crucial fishing regulations, including legal size limits, protection requirements, and eating quality information, helping anglers fish smarter and more legally.

How does the AI fish identification work?

The app's AI is trained on thousands of high-quality images of freshly caught fish, recognizing variations in color, shape, and size. This analysis happens entirely on your device, ensuring it works reliably wherever you are, without needing an internet connection.

What are the costs associated with iDfish?

iDfish operates on a yearly subscription model costing $9.99 per year. New users receive a first month free. The subscription ensures access to ongoing updates for fish images, species data, regulations, and regional closures.

Is iDfish compatible with my device?

The app is available on the App Store. While the AI and core features work offline after initial setup, a Wi-Fi connection is required for the initial download and account creation/login before offline use is enabled.

What are the main benefits of using iDfish for anglers?

Anglers benefit from instant, accurate fish identification, quick access to legal regulations to avoid fines, and information to help maximize the survival of released fish. The offline functionality makes it invaluable for remote fishing locations.
