Eight skies to explore

A whole universe of topics

From the planets next door to black holes and galaxies — every topic is a new adventure, written in plain language for young astronomers.

The Solar System & planets The Moon & eclipses The Sun & the stars Galaxies, black holes & the universe Astronauts, rockets & missions Comets, asteroids & meteors Constellations & stargazing How gravity, light & space work

How it works

Read, play, collect stars

Pick a topic

Choose a sky to explore. Every topic opens with short, illustrated slides — one idea per screen, read aloud on request.

Take the quiz

Friendly questions with a simple explanation for every answer. “I don’t know yet” is always an option — trying counts.

Light your sky

Points become stars, collected on a constellation that grows as your child learns. No timers, no streaks, no pressure.

Inside the app

Calm by design

A deep-sea night sky, warm peach-gold rewards, and nothing that nags. Built to feel gentle at bedtime.

Made for parents to trust

Safe, calm and ad-free

🛡️

No child sign-in

Children never register and never enter personal information. There is nothing in the child experience for a child to type.

🔒

Parental gate

Settings, the optional account, and every route into a purchase sit behind a simple grown-up gate.

🚫

No ads or tracking

No ad networks, no third-party analytics, no behavioural tracking — ever. No links out, no chat.

📶

Works offline

All slides and questions ship inside the app. A connection is only needed for optional backup and purchases.

☁️

Optional backup

A parent can sign in — behind the gate — to back up a child’s progress so it survives a lost or replaced device.

💛

Kind about mistakes

No timers, no streaks, no red crosses. A wrong pick is shown warmly beside the right one, with an explanation.

Free to learn, one-time to unlock

The illustrated slides are always free for everyone, along with free questions in every topic. An optional one-time purchase unlocks the complete question set — you pay once and it’s yours forever. It is not a subscription: nothing renews, and there’s nothing to cancel.
