Point your camera at any wild animal and Critterdex names it on the spot — then turns it into a collectible card. There are 214 to find. A pigeon counts.

Free to start. Your first three catches are on us — no account needed.

See it, snap it, and it’s yours.

No field guide, no guessing. Three taps from spotting an animal to a card in your book. Live animals only — photos of screens don’t count.

  1. Spot

    A fox at dusk, half-hidden in the grass. You’d have walked straight past it.

  2. Snap

    Raise your phone. Critterdex finds it in the frame and names the species within moments.

  3. Reveal

    It lands in your book as a finished card — art, name and rarity, yours to keep.

One book. 214 species.

Everyone starts with an empty book of grey silhouettes. Every catch fills one in. Everyday animals are first-class here — a house sparrow earns its page next to a badger.

Grey means still out there. Colour means already found.

From everyday to once-in-a-summer.

Every card carries a rarity. The animals you pass every day fill the common tiers; the shy and the seasonal reward you with rarer art the deeper you go.
