a0.dev is an AI app builder for mobile. You describe what you want in a chat, and it writes the code for an iOS and Android app, with web deployment too.
Beyond building, it offers one-click publishing to the app stores, built-in payments and growth analytics, so you can earn money from your app in the same place. The company is backed by Y Combinator and says a large community already uses it. There is a free way to sign up and start experimenting.
