How our family studies nature

# 1
Collect
See a bird, plant, bug, fish, or animal on a walk? Open Wildfolio with your kid and snap it together. The moment it's in frame, you'll know the species.
# 2
Learn
The moment you snap, the species details show up. Name, rarity, habitat, diet, a one-line fact. It's saved to your guide automatically.
# 3
Field guide
Birds, plants, bugs, fish, animals... Every find your family makes stacks into the guide by category. The fuller the guide, the more your family learns and remembers together.
# 4
Map
Use the map to see which species live where you're headed next. Pick what to spot this weekend with your kid. A family outing turns into a small nature lesson.

More you can do

Record sounds

Just record a bird call, an animal cry, or an insect chirp, and we'll figure out the species and add it to your guide.

Learning biology through rarity

Common

Easy to spot on a neighborhood walk. Great for your kid's first observation practice.

Uncommon

Shows up at the right season and time. Kids learn 'when and where' species appear.

Rare

Worth an early-morning walk or a trip to a specific habitat. A small family expedition starts here.

Mythic

Worth a weekend trip to spot. Collect rare species and build a precious family memory.

We loved learning nature in person.

Growing up, our families took us outside to see and touch nature, and we learned alongside them.

But watching our younger cousins, all we see is a screen. Nature, learned through a monitor.

We wanted a world where kids meet nature in person instead of through textbooks or screens, and learn alongside their family.

What stays with you longer isn't what you memorized off a screen. It's the plant you pointed at outside, side by side with your family.

We hope more kids get to build memories with their family, learn the name of a bird they spotted together, and tell their friends about it.

Wildfolio is a great starting point that turns the photos kids take into meaningful ecological learning. It isn't a worksheet or a video. It starts from the species your kid actually met, so the curiosity-driven memory sticks longer. A solid educational app for parents and kids to understand nature as data, together.
