Catcharium: Fish ID & Log

Identify a fish. Remember the catch.

Catcharium brings AI-assisted fish identification and your catch journal together. Take a photo or choose one from your library, get a species suggestion, and keep the catches that matter to you.

IDENTIFY AND RECORD
• Identify fish from a photo with an internet connection.
• Save catch photos, dates, lengths, and weights in your private journal.
• Review estimated lengths and enter your own measurements.
• Optionally save fishing locations with your catches.

BUILD YOUR COLLECTION
• Bring saved catches into a personal animated aquarium.
• Track your collection, earn badges, and share catch cards when you choose.
• Explore a 485-entry field guide covering fish and other aquatic animals.

FREE ACCESS
Free use includes photo identification, a catch journal, and basic guide information for catches in your collection. Any paid plans, features, and localized prices are shown in the app before purchase. Service and security limits apply.

YOUR JOURNAL AND DATA
Catcharium creates an anonymous account for private cloud backup. Recovery requires the same account; changing devices or losing its credentials may prevent recovery. Saved, released, and deleted catches, photos, and related cloud data are retained without automatic expiry. Closing your account in Settings clears the device journal and disables account access; cloud data remains retained without automatic expiry. Other scans on active accounts become eligible for cleanup after 90 days; cleanup may be delayed. Request permanent erasure at support@catcharium.app; verification is required. Keep independent copies of important photos.

BEFORE YOU CAST
The app and its field guide support English, Simplified Chinese, Traditional Chinese, Japanese, Korean, French, German, Spanish, Brazilian Portuguese, and Italian. Names outside the guide may remain in English, with scientific names when available. Legal and support webpages are in English.

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