Critter Collection

Every walk outside is a chance to catch something new. Snap it, learn why it works the way it does, and watch your field guide fill up.

Turn a walk outside into a collection.

Snap a photo of any plant, bug, bird, animal, mushroom, shell or even a cloud, and it becomes an entry in your own field guide. Coco, your explorer companion, is there for every find, with a friendly "why?" quiz that teaches the science behind what you just caught.

WHAT YOU CAN DO

• Catch 103 species: plants, insects, birds, fish, mammals, reptiles, amphibians, fungi, minerals, shells and sky
• Answer a "why?" quiz on every discovery and learn something real
• Fill in the silhouettes: species you have not found yet show hints on where to look, what colour and what shape
• Hunt legendary creatures, five-star finds that arrive on a golden card
• Earn badges from your very first find all the way to 100
• Watch a shared habitat map and rarity ranking grow from everyone's discoveries
• Read everything in kana for younger explorers, or switch it off

SAFE BY DESIGN

• Photos are never stored on our servers. Identification happens, then the photo is gone
• Locations are rounded to roughly 5 km, so nobody can tell where you were
• No account, no sign-up, no ads
• Dangerous species such as hornets and vipers always arrive with a warning

Available in English, Japanese and Spanish.
