What it is
Short lessons and small challenges teach programming or system design in a format that works on a phone. It is for beginners and working developers who learn in small gaps of time.
Why it looks interesting
Beginner coding courses are easy to find on the web, and a small new app teaches system design on phones. Mobile-first learning is a test of its own, because writing code on a small screen is hard.
How it makes money
A monthly or yearly subscription with a free first track.
