ChatGPT didn't build my app. But I probably wouldn't have built it without ChatGPT.

I spent a few months building and launching a mobile app with ChatGPT as my primary technical collaborator. Not "generate a logo" or "write a tweet". I mean actual product development: Flutter code, Firebase architecture, database design, bug fixing, App submission, Google Play release, website creation, analytics, experiment design, content creation. The app explores luck, probability, behavioral patterns, and real-world experiments. What's interesting isn't the app itself. It's that before this project I had never shipped a mobile application. ChatGPT didn't magically build it for me.
