Fish Atlas

Explore aquatic life with a beautifully illustrated field guide built for discovery, learning and personal observations. Fish Atlas brings together 100 fish species in an immersive, easy-to-use reference. Browse detailed profiles, explore the environments fish inhabit, compare aquatic worlds side by side and build your own private field journal—all without creating an account. FEATURES • Discover 100 fish species with common and scientific names, characteristics, habitats, diets and conservation information. • Explore seven detailed habitats: coral reef, open ocean, mangrove, river, lake, deep sea and estuary. • Compare habitat depth, temperature, salinity, visibility, currents, learning level and key threats in a clear side-by-side view. • Browse taxonomy and understand how species are related. • Search by name, family, habitat and descriptive tags. • Use photo-led candidate matching with observable field clues to narrow down possible species. • Record sightings in a personal field journal with notes, photos and optional manually entered coordinates. • Track favourites, seen species, catches and aquarium records. • Review collection statistics and conservation topics. • Export and restore a local recovery backup through the Files app. PRIVATE BY DESIGN Fish Atlas does not require an account. The app is designed to work offline, and personal records remain on the device unless the user chooses to export a backup file. IMPORTANT Candidate matching is an educational aid based on the traits selected by the user. It is not a definitive scientific identification. Species illustrations may be artistically generated and should not be used as the sole basis for identification, health, safety, legal or conservation decisions.
