Breakfast
Two heads, one puzzle
One new puzzle a day, from a different room. It fits between the cereal and the shoes.
The zoo where learning feels like playing.
CurioZoo is a place where children learn while having fun: puzzles, science, and stories read aloud by a kinkajou named Kaju. They grow a whole zoo just by thinking. No ads. No chat. Nothing to sign up for.
Coming soon on the App Store

Give Kaju five words.
An example from the app
This is a small taste of what you get in the app: a real game, in Kaju’s real voice. Pick the silliest word you can find. He does the rest.
The app has many more stories and games like this one. There, a child can also say their words out loud. The sound never becomes text, never leaves the device, and goes away when the game ends. The microphone starts off, and only a grown-up can turn it on.
Safe for kids.
Peace of mind for parents.
Here’s how. This is what we left out:
- Ads
- Strangers
- Chat
- Bad content
- Videos not meant for kids
- Endless feeds
- Coins to buy
- Accounts
- Tracking
- Streaks
- Leaderboards
- “Come back!”
- Links for kids
Everything in CurioZoo was made for kids and lives inside the app. Nothing comes in from the internet, and nobody can reach a child through it. So there’s no need to worry about what’s on the screen.
Data we collect about children: none. Progress lives on the device. Purchases go through Apple, behind a grown-ups’ gate.
Even Kaju knows when to stop.
After a while, Kaju yawns, stretches and offers a break. He encourages kids to put the screen down and go move. Two equal buttons, and no sad face, whichever one they pick.
Coming to the app: a section for getting active. Jump, stretch, run and explore, away from the screen.
Nobody here says “lesson.”
Ask a kid what they did today. “I saved an elephant.” They won’t mention the physics. Tap a card to see what really happened.
Screen time that turns into family time.
Most apps keep kids to themselves. CurioZoo keeps sending them back with something to show, try or talk about. Here is one table, on one day.
After school
A real experiment
Home Labs use things from the kitchen. Why does a peeled orange sink? Guess together, then find out.
Dinner
Something to talk about
A note for grown-ups says what they explored this week, with one good question.
Tonight, ask (coming soon)How can a mouse lift an elephant?
Bedtime
A story, side by side
Kaju reads a two-minute episode, and every game has drawn a little more of the map. This one is for sitting together.
A look inside the app.
Real screens from CurioZoo. Just a few of the games.
What’s inside.
Stories read to you
Kaju reads The Voyages of the Wonder aloud, and each word lights up. Readers read along. Not-yet-readers listen and follow.
A zoo that grows with thinking
56 animals to earn, care for and make laugh, and 8 of them are rare, with tracks to follow. No animal costs pretend money. They’re earned by thinking.
Home Labs
Coming to the app29 real experiments, with no fire and no strong chemicals, and a picture and a voice for every step. First you guess. Then you find out.
The Sinking OrangeDancing RaisinsString TelephoneBouncing Bubbles
Little mode
Big talking doors, for children who can’t read yet.
No internet needed
Everything is inside the app. Nothing to wait for, and nothing goes out.
A corner for grown-ups
Behind a grown-ups’ gate: the weekly note, screen limits and every setting.
“You tried another way. That’s how puzzles open.”
Praise here is for what a child did, never for what a child is. And when something goes wrong, they hear “Let’s look again.” Never “Wrong!”
A zoo full of rooms to explore.
Here are some of them, with more on the way. Each room has a keeper waiting. Tap one: they like being said hello to.
