The core experience

Stories made just for them

In the app, your child is called by their own name in every story. That's not a gimmick: it's what makes them recognize themselves, feel attached and come back the next evening.

  • Your child's name in every adventure, inserted by code—never invented by AI.
  • Emma & Theo stories: recurring characters kids genuinely bond with.
  • A free printable coloring page with every episode, one click to print.
  • The Advent Calendar: a surprise every morning from December 1st to the 24th.

What the app does

Three promises kept

Not another screen that winds kids up. A gentle ritual that soothes children and gives parents a breather.

The Emma & Theo stories

A new episode regularly, with your child's name at the heart of every adventure. Getting ready for Christmas, playing in the snow, bonding with the characters.

A free printable coloring page

Every story unlocks a page from our collection to print. Kids color it, stick it up, collect them. The experience continues on paper, away from the screen.

The Advent Calendar

A surprise every morning in December. The ritual kids ask for by themselves, all the way to the 24th. The most anticipated countdown of the year.

Simple and fast

How it works

Three gestures. The rest? Pure magic.

Open today's story

2 to 4 minutes, read or listened to together. Perfect at bedtime, in the morning or after school. The voice, the name, the atmosphere.

Print and color

One click to print the page linked to today's story. Markers, pencils, off you go. The screen goes off, the drawing begins.

Come back tomorrow

"Tomorrow, do we find out about the little reindeer?" The next episode is waiting, the cliffhanger is gentle, the child can't wait. The ritual is set.

Built to last

Designed to build a habit, never a dependency

A gentle routine, light rewards, a collection that makes them want to come back—no pressure, no guilt, ever.

A collection to complete

Pages, badges and little rewards: kids want to "collect them all," at their own pace, with no pressure.

Heroes they truly love

Emma, Theo and their reindeer friend appear in every episode. Kids know them, love them and come back for them.

The name: the emotional lock

Your child is IN the story. That single detail is what makes the app irreplaceable and genuinely unforgettable.

Questions

What parents ask us

What age is it for?

The Emma & Theo app is designed for children aged 4 to 8. The stories are gentle, the vocabulary accessible, and the coloring pages use bold outlines suited to small hands. Older children (8 to 12) may also enjoy the more detailed coloring books from our collection.

Is the app available yet?

Not yet. We're opening the doors for Christmas 2026. Waitlist members will be the first to receive access and will benefit from the founder's rate for life. Sign up so you don't miss it.

How much does it cost?

The app will offer a free plan (1 story per week, sample coloring pages) and a premium subscription to unlock everything. The planned price is around $4.99 per month or $39 per year. Waitlist founders will receive a special rate locked in for life—the best price possible, reserved for early members.

Will my child be glued to the screen?

No—that's at the heart of our philosophy. The story takes 4 minutes, then the child prints their page and colors it, away from the screen. Screen time is short and intentional. The rest is paper, markers and joy.

How does name personalization work?

Your child's name is woven into the story text by code. It is never drawn or generated by AI—which means it will always be spelled correctly and look right, whatever the name.

Do I need to create an account?

For the personalized experience (name in stories, coloring collection, progress), a simple email account is all you need. No complex password: a magic link in your inbox and you're in.

Are the coloring pages really printable?

Yes, in high resolution, ready to print on any home printer. A4 or US Letter format, pure black outlines, white back. The exact same standards as our KDP paperback collection.
