Critter Collection
Find, snap & collect nature
Free · Designed for iPad. Not verified for macOS.
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.
