The Library
Reading and language
Rhymes, first sounds and silly words. Reading a real book together counts the most.
A gentle game for ages 3 to 8
Find a mystery egg. Care for it together. See who hatches.
Your child raises little creatures by reading, counting, drawing, exploring and being kind. What hatches depends on how they cared for it. Every day ends with something to do away from the screen.
- Ages 3–8
- 8–20 minutes a day
- No ads or purchases
- iPad first
How a day goes
Short, calm, and it always has an ending.
A day of play takes about 8–12 minutes for ages 3–5 and 15–20 minutes for ages 6–8. Then the Hollow goes to sleep until tomorrow.
-
Tend the egg
Each egg has one or two small needs. A blanket when it’s cool, a song when it’s dim, quiet company when it’s restless.
-
Choose a place
Your child picks where to go: read in the Library, trace in the Workshop, read faces in the Meadow. The guide never pushes.
-
Watch it grow
The egg changes a little every day. When it hatches, the game explains exactly what your child did to shape it.
-
Say goodnight
The Hollow falls asleep, and the guide suggests one thing to do off screen, like reading a page to someone.
Places to explore
Six places, each one a different way to grow.
Activities adjust to your child’s age and pace, so a three-year-old and a seven-year-old each find the right challenge.
The Market
Counting and number sense
Which pile is bigger? Count out four for the shopkeeper. Weigh, measure and make change.
The Workshop
Drawing and building
Trace paths, copy shapes and put things together, step by step and with both hands.
The Meadow
Feelings and friendship
Read faces, take turns, and figure out how to make things right after a mix-up.
The Trail
Exploring and adapting
Short trips where the path changes. Pack wisely, try a new way, and keep going.
The Burrow
Calm and patience
A quiet space with no goals, open from anywhere. Watch a seed grow, breathe, and come back when ready.
Every creature is earned
What hatches is up to your child, never to luck.
“You read or sang to your egg on 5 of 7 days, more than anything else.”
- Nothing is random and nothing is for sale. The same care always hatches the same creature.
- Nothing bad ever happens to a creature. Missing a day costs nothing, and every egg hatches on time.
- Every creature has its own abilities and quests. There are no “rare” labels and no comparing with friends.
Made for families
Designed to put the tablet down, not keep it up.
A real ending
When the day’s play is done, the Hollow sleeps. Extra time earns nothing extra.
Off-screen counts
Reading a real book, hopping five times or finding a triangle at home all help an egg grow.
No ads, no purchases
No in-app purchases, no ads, no tracking, no chat and no leaderboards.
Grown-ups hold the keys
Settings, reports and any link out of the app sit behind a parent PIN.
Works offline
Everything works without a connection. Progress backs up when you’re online again.
Your data, your call
Export or delete your child’s data any time. Camera and microphone stay off unless you turn them on.
Gentle on every kind of sensory system
Turn on Calm Palette for softer colors, reduce motion, or set a volume ceiling. Nothing ever flashes or shakes. Every screen a child uses works without reading.
For grown-ups
A short weekly story, not a scorecard.
It’s a game, not a test. It never scores, grades or compares your child. Behind the parent PIN, you’ll find:
- This week’s story
- What your child explored, in a sentence or two.
- Strengths
- One or two things your child is good at right now.
- One thing to try
- A single, simple idea for the two of you, like counting steps on the way to the park.
- Time, honestly
- Minutes per day on screen, and how much progress came from off-screen activities.
If a skill stays harder for a while, you’ll get a plain-language note and a one-page summary you can bring to your pediatrician, if you choose. You decide what is shared and with whom.
Questions
Things parents ask us
Is this a test or a screening?
No. It’s a learning game. Your child is never quizzed or scored. Behind the scenes, the app notices how play is going so it can pick the right activities and share strengths and ideas with you. It doesn’t diagnose anything, and it isn’t a medical device.
What ages is it for?
Ages 3 to 8. Younger children get bigger buttons, shorter days and simpler activities. Older children get longer quests, more places and more choices.
What devices will it run on?
We’re starting on iPad with families in the United States. iPhone and Android tablets will follow.
Do I need to turn on the camera or microphone?
No. Every activity works with them off. If you turn them on, they’re used only during activities that need them, like saying a silly word out loud or copying a face. You can switch them off or delete recordings at any time.
How much screen time is it?
About 8–12 minutes a day for younger children and 15–20 for older ones, with a clear stopping point. Playing longer doesn’t earn more.
Who makes it?
Levian Health, a small team that started with one family’s long wait for answers. The app is built in collaboration with researchers at Stanford. Read our story.
Early access
Be one of the first families to play.
The app is built and in early testing. We’re inviting U.S. families with an iPad to try it first and tell us what they think.
- Invites go out in small groups
- We’ll email you when your invite is ready
- Your feedback shapes what we build next
