The Curio Island hub: a 3D island with labs for colour, chemistry, physics, maths and biology

Three age bands, separate games

Every child gets labs made for their age.

Pick an age when you add a player. A five-year-old never sees molecules, and an eleven-year-old is never handed toddler games.

For parents

Made for families, from the first screen.

Curio Island is built for children and follows Google Play's rules for apps in its Families programme.

No accounts, no personal data from children

Progress stays on the phone. There is no sign-up, chat or social feed.

Child-safe ads, only at breaks

Ads are non-personalised and rated for children. None in the first few minutes and never in the middle of a game.

A grown-ups' corner

Sound, voice, music, language, players and purchases sit behind a parent check.

One small purchase removes all ads

A one-time Ad-free option, bought by a grown-up. Coins in the game are earned by playing and can never be bought.

Questions

Good to know

When can we download it?

Curio Island is in testing on Google Play now and launches soon for Android. Email us and we'll tell you the day it's out.

Is it free?

Yes, free to download and play, with child-safe ads at natural breaks. A one-time purchase removes all ads.

Which ages is it for?

Four to twelve, in three bands: Explorer (4–7), Tinkerer (7–10) and Inventor (10+). Each band has its own labs, and several children can have their own player on one phone.

Does it work in Hindi?

Yes. Every screen switches between English and Hindi, and the youngest children hear tasks read aloud in either language.

Does it need the internet?

The labs work offline. Ads need a connection.

Is there an iPhone version?

Not yet. Curio Island is launching on Android first.
