Features

Identify fish however you like

Take a photo, describe the fish in your own words or answer a few multiple choice questions. Fin tells you which fish you saw, even when two species look almost alike.

Keep a logbook of every catch

Save each catch and sighting with the place and the date. Your Spotted, Caught and Favourites lists grow with every trip, so you always know what you found and where.

See what swims in your water

Draw an area on the map and see which species live there. You know what to expect before you head out, and your own catches show up on the map.

Everything about 12,519 species

Every fish has its own page with photos, a range map, size, diet and protection status. You know what you caught, where it lives and whether it is safe to handle.

Learn to recognise the fish

Short quizzes and games teach you the species of your own water in a few minutes a day. Next time you know the fish before you need to look it up.

Share your catches

Post your catch in the fish feed, follow other anglers and divers and see what they find. Your best moments land with people who get it.
