Geeky Lessons for Anyone
Micro courses: AI, tech & more
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
How AI works, how computers work, what companies know about you, how products get decided, and the real sky behind your sign. Every course starts free.
Five short courses on things you use every day and were never really taught. Every course starts free, and one purchase opens all of them.
THE COURSES
Data to AI: how AI works, starting with the data on your phone.
Product Management: how the things you use every day get decided.
Your Data Rights: what companies collect, what gave them the right, and what you can do about it.
How Computers Work: what's inside the box, and how to fix it when it's slow.
Star Signs: the real sky behind your sign, and why the horoscope can't forecast.
HOW IT WORKS
Each course is 24 modules of short lessons, and each one follows a small cast of characters through a story. You play with an idea before it gets its name, then check yourself with a quick question. Pick any course from your shelf. The ring around each one fills in as you go, so you can hop between courses and always pick up where you left off.
WHAT IT COSTS
The first part of every course is free. A one-time purchase unlocks every lesson in every course. No subscription and nothing else to buy.
WHAT IT DOESN'T DO
No account and nothing to sign into. No ads. Your progress stays on your phone, and every course works offline.
