Rox’s Secret Code

FWA Site Of The Day • Apple Store App of the Day

An empowering picture book and companion AR app that inspires kids to code. I created Secret Code to help close the gender gap in STEM and create more diversity in tech.

Why we made Secret Code:

The story behind the book.

Secret Code is about a tech-savvy girl who, instead of cleaning up her messy room, codes a robot to do it for her. But the story is about more than technology: themes touch on of bravery, curiosity and leadership – values that lead to a fulfilling future.

Rox’s Secret Coding Game

At the end of the book, the story isn't over. Turning inspiration into action, you can download our app that lets kids customize their own robots and learn coding principles.

Kids can design their own amazing robot creations.

A customizable book that makes YOUR girl the hero.

When you buy the book on our site, you personalize the hero’s name, skin color, hair color/style and eye color, so she looks just like the girl you want to inspire – and any girl can have a relatable role model.

Parent Customization 

Mixed race parents, same sex parents, and single parents are common in the real world, but nonexistent in children's books. By letting people customize parents, any family could see themselves in Secret Code – making it the most inclusive children's book, ever.


We launched Secret Code with a video that inspired parents to teach their girls to #BreakStereotypes so they'll grow to be unstoppable.

The best part about writing Secret Code? Hearing from parents and fans.

We hear about kids who want to read it over and over again. Girls who start playing robot instead of princess. And kids who dress up as Rox.
