Your child as the hero: a samurai folktale from Japan and a knight’s life in the Middle Ages.
See all 2 booksDeep in the Amazon, under the pyramids, out among the stars: an adventure made just for your child and you, with something new to discover on every page.

One everyday photo of your child, and one of you if you’re in the story (the Samurai book is just your child). We use them only to draw the characters.

Each page is a moment in the story, a true fact and a question your child answers from the picture: what Saturn’s rings are made of, how Triceratops got its name, what a knight wore.
Ten hardcover picture books on four shelves. Each is a story set in a real place or time, with your child drawn into every page. Tap a book to look inside.

The ten picture books are on sale now. The Cradl app, coming soon, brings every world, its books and games, and the parent tools together in one place.
On an Android phone or a Fire tablet, the Cradl app notices which YouTube videos are played, which apps are used and which sites are visited, by name. On an iPhone, you sign in once to your child’s Google account from your own phone and Cradl reads their YouTube history from there. Cradl then investigates the creators, products, apps and communities that keep appearing, and sends you a short report every week, with an email when something new needs your attention.
Those set time limits and block apps. Cradl tells you who is influencing your child and what they’re being sold: which creators have their attention, what those creators promote, and what 18+ content or communities reached them. Most families keep the free tools for limits and use Cradl to know.
No. Nothing is installed on the iPhone or iPad. You sign in once to your child’s Google account from the Cradl app on your own phone.
No. You sign up on your phone, and the child’s phone is set up in about three minutes, together with your child.
Android phones and tablets, Amazon Fire tablets, and iPhone and iPad through their Google account.
