Installation

Expo
Bare React Native

Install the package

expo install picks a version that matches your SDK:
Terminal window
```
npx expo install expo-check-installed-apps
```

Add the config plugin with the apps you want to check

{
  "expo": {
    "plugins": [
      [
        "expo-check-installed-apps",
        {
          "android": ["com.whatsapp", "com.android.chrome"],
          "ios": ["whatsapp", "googlechrome"]
        }
      ]
    ]
  }
}

More on this in Configuration.

Rebuild the native app
Terminal window
```
npx expo prebuild --clean
npx expo run:android   # or: npx expo run:ios
```
Or create a new development build with EAS: eas build --profile development.

Set up Expo modules

If your project doesn’t use Expo modules yet, follow Installing Expo modules first (npx install-expo-modules@latest).
Install the package
Terminal window
```
npm install expo-check-installed-apps
```
Install pods
Terminal window
```
cd ios && pod install
```
Declare the apps you’ll check

Without config plugins, edit AndroidManifest.xml and Info.plist by hand. See Manual setup.
Rebuild both apps.
