Heero · a game for ages 3 to 9
A game your child loves. Peace of mind for you.
In Heero, your child designs their own hero, dresses them up and plays short games with them. The hero giggles, wobbles and cheers back. Each week, you get a short story of how your child is growing, and a clear next step if something ever needs a closer look.
- Ages 3–9
- 8–12 minutes a day
- No ads or purchases
- Weekly parent insights
- iPad first
Poke me! Tickle me! Let’s play!
Try it
Meet the hero and play three of the games, right here.
A short look at the real thing, for grown-ups: the hero in the park and three of the games, as they are in the app. The games door is on the right. Sound starts once you tap in. Nothing you do here is saved or sent anywhere.
Loading Heero…
The demo is made for a tablet-sized screen. On a phone, open it on its own page and turn your phone sideways.
Open the demoThis is a demo build, not the app itself: there is no setup, no account, no parent view and no saving, and it uses a mouse or a finger in place of the iPad’s touch. The app is for iPad and is being tested with families now; join the waitlist to be invited.
Meet your hero
A hero that’s all theirs, and plays back.
Heero opens straight onto your child’s hero, already awake and waiting. No menus, no reading, nothing to figure out first. Sparky, a friendly guide, explains everything out loud.
-
Design them
Pick a creature, choose its colours, give it a name and a cape. A hero that looks the way your child imagines.
-
Play together
Poke, tickle, swing and spin them. Every touch gets a face, a wobble and a sound, from giggles to sneezes to dizzy stars.
-
Play games
Through the games door: short games of counting, words, shapes, focus and feelings, played against a friendly rival, Sparky or their own best.
-
Say goodnight
Tap the moon and the park turns to night. A lullaby plays and the hero tucks in until morning.
The arcade
Quick games that feel like play, and build real skills.
Each game takes a few minutes and adjusts to your child’s age and level. Win a medal, beat your best, then pick a prize: a small one now or a bigger one after the next game.
Which Is More?
Counting and number sense
Which pile is bigger? Count some out, place numbers on a line, weigh and compare.
Follow the Path
Drawing and fine motor
Trace winding trails and copy shapes with a fingertip, steady and smooth.
Word games
Reading and language
Rhymes, first sounds and building words, with Sparky saying every one out loud.
Sort and switch
Flexible thinking
Sort by colour, then the rule changes to shape. Keeping up is the fun part.
Read the faces
Feelings and friendship
The hero shows a feeling. Your child works out what it is and what would help.
Hero missions. For bigger adventures, your child’s hero heads out on missions: hunting playful monsters and taking on a boss. Nobody gets hurt. Beaten monsters turn friendly and float away.
Dress them up
Earn outfits, collect them all, and make your hero yours.
Capes, masks, hats, shoes and more, earned by playing and kept forever.
- Every outfit has a clear, fixed price in coins earned by playing. Nothing is random, and nothing is for sale.
- Nothing is ever lost. There’s no game over, and a missed day pauses the daily gift, never resets it.
- Your child competes with a friendly rival, Sparky or their own best. Never with another child, and no leaderboards.
Made for families
Big fun, small doses, and nothing to worry about.
Short and sweet
About 8–12 minutes a day. Coins and prizes stop at a daily cap, so playing longer earns nothing extra.
Safe by design
No chat, no strangers, no friend requests and no comparing with other children.
No ads, no purchases
No in-app purchases, no ads and no tracking.
Grown-ups hold the keys
Settings, reports and any link out of the app sit behind a parent PIN.
Never sad because of your child
The hero gets startled, wobbly or sleepy, then grins again in a moment. It never sulks, nags or suffers when your child is away.
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 colours, reduce motion, set a volume ceiling, or tap the speaker by the hero to switch all sound off. Flashes and shakes happen only in the action missions, and never when motion is reduced. Every screen works without reading, because Sparky says everything out loud.
For grown-ups
A short weekly story, not a scorecard.
Your child is never graded, labeled or compared with other children. Behind the parent PIN, you’ll find:
- This week’s story
- What your child played and 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 which games they chose.
Most weeks, the story is simply reassurance that your child is growing well. If something needs a closer look, here’s what happens.

Peace of mind
If something needs a closer look, you’ll know early, and know what to do.
Most parents just want to know their child is on track. For most children, that’s exactly what the weekly story tells you. When it isn’t, you won’t be left guessing.
Questions
Things parents ask us
What is Heero?
Heero is our first app: a game where your child designs a hero, plays with them, dresses them up and plays short learning games together. Underneath, it quietly notices how your child is developing, so you get a weekly story of their strengths and early notice if something could use a closer look.
Is this a test or a screening?
No. It’s a learning game, not a diagnostic test, and your child is never graded or compared with others. Behind the scenes, the app notices how play goes over weeks, so it can pick the right games, show you your child’s strengths, and let you know early if a skill could use a closer look. It doesn’t diagnose anything, and it isn’t a medical device.
What ages is it for?
Ages 3 to 9. Every game adjusts to your child’s age and level, so younger children get simpler versions and older ones get more of a challenge.
Is it a fighting game?
No. It’s a superhero game with lots of slapstick, but nobody is ever hurt. In the missions, beaten monsters turn friendly and float away, and the hero is never sad or angry because of your child.
What happens if the app notices something?
You’ll get a plain-language note explaining what we noticed and what it may or may not mean, ideas to try at home, guidance on who to talk to, and a one-page summary you can share with your pediatrician if you choose. See how it works.
Is there anything for children under 3?
Not yet. Heero is designed for ages 3 to 9. Tools for the earliest years, from birth to 3, are next on our roadmap. Join the waitlist and choose “Under 3” so we can let you know.
What devices will it run on?
It launches on iPad first, and families anywhere in the world are welcome to join the waitlist. iPhone and Android will follow.
Do I need to turn on the camera or microphone?
No. Every game works with them off. If you turn them on, they’re used only during the activities that need them, like copying a face in the mirror. You can switch them off or delete recordings at any time.
How much screen time is it?
About 8–12 minutes a day. Coins and prizes stop at a daily cap, so playing longer doesn’t earn more, and the bedtime door lets your child wind down with their hero.
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.
