This document discusses the Lean UX process for building apps that users love. It emphasizes starting with user research to understand problems, rapidly prototyping solutions, and getting frequent feedback to iterate designs. The process involves creating personas, testing assumptions with users, prioritizing problems, making paper/digital prototypes, getting early feedback, and continuously improving through multiple iterations. The goal is to build something that solves the right problems in a way users enjoy.
