Coding that actually goes somewhere
Most “coding for kids” apps are drag-and-drop blocks kids outgrow. Rocket Cadets teaches the real language — the one professionals use.
Real Python, not just blocks
Kids type actual Python in a real editor — the upgrade path for anyone who's outgrown Scratch. 15 worlds, 80+ space missions.
AI literacy, done right
Hands-on playgrounds teach how AI actually works — not a chatbot to talk to. Nothing your child does is sent to any AI service.
$14.99 once. That's it.
Less than one month of a typical coding subscription — and it never renews. Family Sharing covers siblings on Apple devices; on the web, one code covers the family's computers.
Works on a plane
100% offline. Every lesson, playground and demo runs with no internet — proof that nothing leaves the device.

Why I built this
I'm a parent and an engineer. I built the app I wanted my own kid to have: one that teaches real Python and how AI actually works, works on a plane, and collects literally nothing. World 1 is free — see if your kid lights up.
