a0.dev

Build and launch native mobile apps from plain-English prompts

About a0.dev

a0.dev is a Y Combinator-backed AI platform that turns plain-English descriptions into real React Native mobile apps. Users describe an idea, watch a live simulator preview in the browser, and refine the app conversationally without setting up Xcode or Android Studio. Because the output is a genuine Expo project with exportable source code, finished apps can be submitted to TestFlight, the App Store, and Google Play, making it aimed at indie builders and founders shipping native products.
