A clinician turned her book into a working app for busy-brained kids, no code

An installable, offline app with thirteen guided practices for neurodivergent children, built without writing a single line of code.

Dr Danielle Baillieu works with neurodivergent children and wrote a book on mindfulness for busy brains. In AI Mastery, a loose idea became a real app that keeps her practices in children's hands after therapy ends. It is a moving example of expertise finally getting the tool it deserved.

Before

Danielle had a mission: to build something for neurodiverse kids that mainstream mindfulness quietly excludes. She already used her own exercises with clients and patients, and had written a book for parents. But the app was only a loose idea, and writing code was not something she did.

“My mission: to build something for children's mental health — for the neurodiverse kids that mainstream mindfulness quietly excludes.”

In their own words

The turning point

AI Mastery showed her how to build with AI tools. She used Claude Code for the app, the assessment and the legal and privacy pack, ChatGPT for the illustrations and Suno for the Anchor Song. Her own clinical knowledge shaped the thirteen practices themselves.

“Now, when therapy ends, they can keep using the web app to reach the practices themselves.”

In their own words

After

She now has a real, working, installable, offline app with guided practices, an assessment engine, a growing-world reward system and a legal pack wired into the right screens. It is a fast first version, with voice recordings to be redone properly, but everything works. She feels ready to perfect it, build a version for teens and use the same process for quick assessment apps in her practice.

What it lets people do

Children can keep reaching their practices when therapy ends, for worries, getting to sleep and more. Sessions welcome movement, show time as a shape, and make quitting halfway a non-event, with no streaks or scores. Nothing leaves the device, so a child's privacy is protected by collecting nothing at all.

What they learned

Deep expertise plus the right AI process is enough to build something real, fast. She learned that a first version does not need to be perfect to work, and that the same method can now serve many more needs in her practice.

“I feel ready now to perfect it, then build a version for teens.”

https://velvety-pixie-df2176.netlify.app My mission: to build something for children's mental health — for the neurodiverse kids that mainstream mindfulness quietly excludes. I started with a loose idea — "an app for children's mindfulness for busy brains," to complement my book. It became a real, working, installable, offline app: thirteen guided practices, an assessment engine, a growing-world reward system, and a full legal pack wired into the right screens — built without me writing a single line of code. WOW.!Only possible because of AI Mastery. I already use these mindfulness exercises with my own clients and patients, who are neurodivergent — ADHD, ASD and beyond. Now, when therapy ends, they can keep using the web app to reach the practices themselves. Each one is designed for something these children struggle with — worries, getting to sleep, and more. This is a fast first version. The voice recordings were done in a hurry on my iPhone to hit the deadline and will be re-recorded properly later — but everything works. How it was actually made: - Claude Code — the app, the assessment, the legal and privacy pack - Suno — the Anchor Song (such fun — I love it ) - ChatGPT — the illustrations for the book and the app - My own clinical knowledge — the thirteen practices themselves I feel ready now to perfect it, then build a version for teens. And I can already see myself using this exact process to spin up quick assessment web apps for my practice. Formal Blurb: Ask a busy-brained child to sit still, close their eyes and breathe quietly for ten minutes, and you've asked them to do the one thing their brain finds hardest. Then they feel they've failed — at relaxing, of all things. Busy Brains is built the other way round. It's the companion app to Dr Danielle Baillieu's Mindfulness for Busy Brains, turning the book's thirteen practices into guided sessions a child can actually finish: movement is welcome, time shows as a shape rather than a number, and quitting halfway is designed to be a non-event — no streaks, no scores, nothing to lose. The opening assessment is the book's own Busy Brain Check questionnaire. The Anchor Song, the illustrations on each card, and the guiding principle — do them with your child, not at them — all come straight from its pages. The book teaches the parent; the app sits in the child's hands. Nothing ever leaves the device — because the safest way to protect a child's privacy is to collect nothing at all.
