Build and Publish a Full-Stack Mobile App with AI
Building a production-ready mobile application once required a dedicated team of frontend, backend, and DevOps engineers. In 2026, modern AI tools have collapsed that pipelineβan individual developer can now take an idea from concept to the App Store.
In a comprehensive new tutorial published on the freeCodeCamp.org YouTube channel, you'll learn how to build and publish CodexGram, a full-featured, Instagram-style social media application. Moving well beyond superficial "vibe coding," this course emphasizes deliberate planning, reproducible design prompting, robust backend integration, and strict adherence to App Store review standards.
Tech Stack
CodexGram is built using:
- Expo (React Native) with TypeScript for cross-platform development
- NativeWind (Tailwind CSS for React Native) for styling
- Expo's liquid-glass Native Tabs for navigation
