Tambo uses the same `@tambo-ai/react` SDK for Expo and React Native as it does for web apps. Hooks like `useTambo()` and `useTamboThreadInput()` work the same way — you just build native UI instead of using the pre-built web components.

## Create an Expo app

```bash title="Create from the Expo template"
npx tambo create-app my-mobile-app --template=expo
```

Or add Tambo to an existing Expo project:

```bash
npx tambo full-send
```

The CLI detects Expo and skips web component installation automatically.

## Setup

Wrap your app with `TamboProvider` the same way you would in a web app:

```tsx title="App.tsx"
import { TamboProvider } from "@tambo-ai/react";

export default function App() {
  return (
    <TamboProvider
      apiKey={process.env.EXPO_PUBLIC_TAMBO_API_KEY!}
      userKey="user-1"
      components={components}
      tools={tools}
    >
      {/* Your React Native content */}
    </TamboProvider>
  );
}
```

## What works in Expo

The SDK is framework-agnostic. Everything that doesn't depend on the DOM works out of the box:

* **All hooks** — `useTambo()`, `useTamboThreadInput()`, `useTamboComponentState()`, etc.
* **Component registration** — Register React Native components the same way
* **Tools** — Define and use tools identically
* **Streaming** — Progressive prop updates work the same
* **Thread management** — Message history, thread switching, all of it
* **MCP** — Connect MCP servers the same way

The only thing that doesn't carry over is the pre-built UI components from the CLI registry (`tambo add`), since those use DOM elements and Tailwind CSS. Build your chat UI with React Native components instead.
