description	Expo React Native development platform. Use for React Native apps.

Expo

Expo is an open-source framework for apps that run natively on Android, iOS, and the web. It builds on top of React Native, providing a curated set of tools and libraries (SDK) to simplify the development lifecycle.

When to Use

• Building React Native apps without managing Xcode/Android Studio projects manually.
• Needing fast Over-the-Air (OTA) updates via EAS Update.
• Rapid prototyping with the Expo Go app.
• Teams that prefer a "Managed" workflow but still need native capabilities (via Config Plugins).

Quick Start

# Create a new app with Expo Router (default in 2025)
npx create-expo-app@latest my-safe-app
cd my-safe-app
npx expo start

// app/_layout.tsx
import { Stack } from "expo-router";

export default function Layout() {
  return (
    <Stack>
      <Stack.Screen name="index" options={{ title: "Home" }} />
    </>
  );
}
