A family field guide

A painted field guide to the creatures you keep, and the ones you find outside.

Critterbook holds 36 hand-painted creatures. Point the Bug Lens at what your kid found and it names what it sees on the phone, where the photo stays. The Journal fills in as the family finds them. Free, private, offline.

Feature 01

The painted guide

Thirty-six creatures, each one hand-finished as a painted plate.

Snakes, frogs, butterflies, the quiet ones in the soil. A shelf worth coming back to.

Feature 02

The Bug Lens

Point the phone at what you found and the Bug Lens names what it sees, right there on the device.

The photo never leaves the phone. When it isn't sure, it says so, and shows you the closest plate.

Critterbook Journal, a collection wall filling in as the family finds creatures.
Feature 03

The Journal

Every creature the family finds presses into a shared collection wall.

It fills a little at a time, and the empty plates are their own kind of invitation.
