You are no longer just learning theory — today, we built and shipped your first real AI-powered mobile app.

Welcome to Video #7 of AI Mobile Engineer 2026 by The Techzeen and Project #1 — where we build a working AI Chat App using React Native, Expo and the Gemini API.

In this project, we combine AI tools with real mobile engineering: writing professional prompts, using Claude as an AI coding assistant, debugging AI-generated code, securing API keys with .env, and testing the finished application on a real physical device using Expo Go.

What We Built & Learned
AI Chat App using React Native + Expo
Connect React Native with the Gemini API
Write professional AI prompts
Use Claude as an AI engineering assistant
Debug real AI-generated errors
Understand the importance of .env and environment variables
Avoid hardcoding sensitive API keys in your source code
Run and test the AI app on a real physical device with Expo Go
Follow an AI-assisted development workflow without blindly trusting AI-generated code

This is your first step from learning React Native → building real AI-powered mobile applications.
