Nice app

Just started using but so far so good. Great for keeping tabs and journal of your catches. Can’t wait to see more updates.

Great app!

It is a fantastic idea for an app, it now lets users select the correct species, they have added micro fish, and the app is way more fun! The only issue is that the report button is gone, meaning one can’t report a wrong identification and can’t request a new species since the ai often times never said unidentified aquatic catch, making it near impossible to request a new species.

Amazing app

I love the fact that you can just take a picture and it will add it to the aquarium I feel like they should add some more features like taking a photo of the pond and weather and it telling you where and what lures/jigs to use. Love the app.

Very Good !!

I like the way this app is designed . I haven’t explored the pro version but will be giving it a try soon . I mainly got this so I can log every bass I catch . What got me to download this app was a different species I accidentally caught . I like that it gives you the option to size your fish but I wish it would have an option for weight as I fish trophy bass . That would make it a 5 stars ⭐️ and maybe reflect that on the aquarium fishes based on length and size . (Why is my little sunfish as big as my 3lbs bass 😭) but yes little details like that would make this an excellent app overall .

Love the app

I first found it from the YouTube channel (which is actually a good channel)and have loved it since.it always identified the fish correctly and it gives you the option to pay one time instead of doing a annual or monthly fee for the pro version.

FAQ

How does Catcharium identify fish?

Catcharium uses AI to identify fish species from a photo you provide. This feature requires an internet connection. The app suggests a species, which you can then confirm and save to your journal.

What information can I log about my catches in Catcharium?

You can log catch photos, dates, and lengths. You can also edit the species, length, and location of saved catches. The app offers estimated or device-assisted lengths, and you can enter your own measurements.

What are the benefits of Catcharium Pro?

Catcharium Pro unlocks the complete 479-entry field guide, allows searching by localized, English, or scientific name, provides fishing tips, and offers higher-resolution saved photos. It also removes reasonable service and security limits.

How do I subscribe to Catcharium Pro and manage my subscription?

Pro is available via monthly or annual auto-renewing subscriptions, or a one-time lifetime purchase. You can manage or cancel your subscription in your Apple Account settings at least 24 hours before the current period ends. Deleting the app does not cancel a subscription.

Does Catcharium have ads?

No, Catcharium does not contain advertisements. The app is ad-free, allowing for an uninterrupted user experience.

What languages does Catcharium support?

The app and its 479-entry guide support 10 languages. However, names outside the guide remain in English, with scientific names provided when available. Legal and support webpages are in English.

Is Catcharium accurate for fishing rules and safety?

AI identifications and length estimates can be inaccurate. It is crucial to verify fishing rules, protected species, catch sizes, and animal or food safety with authoritative sources. Catcharium is not a certified measuring tool.

How is my catch data stored and backed up in Catcharium?

Catcharium creates an anonymous account for private cloud backup. Signing in with Apple or Google is optional but recommended for restoring your backup on a different device. Without a linked sign-in, changing devices may prevent recovery.
