#Alternatives

Some features require Quest-specific packages that provide the same APIs as their mobile counterparts.

#In-App Purchases

#expo-iap

The expo-iap library supports Meta Horizon OS billing:

npm install expo-iap

Follow the expo-iap Horizon OS setup guide.

#Use Cases

• Premium content unlocks
• Subscriptions
• Customization items
• In-app currencies
• One-time purchases

#Notifications

#expo-horizon-notifications

Use expo-horizon-notifications as a drop-in replacement for expo-notifications:

npm install expo-horizon-notifications

#Migration

Simply change your import:

// Before
import * as Notifications from 'expo-notifications';

// After
import * as Notifications from 'expo-horizon-notifications';

The API is identical, so no code changes needed.

#Example

import * as Notifications from 'expo-horizon-notifications';

Notifications.setNotificationHandler({
  handleNotification: async () => ({
    shouldPlaySound: false,
    shouldSetBadge: false,
    shouldShowBanner: true,
    shouldShowList: true,
  }),
});

Notifications.scheduleNotificationAsync({
  content: {
    title: 'Notification!',
    body: 'It works on Meta Horizon OS!',
  },
  trigger: null,
});

Note: Expo Push Service is not supported on Meta Quest.

#Location Services

#expo-horizon-location

Use expo-horizon-location for location services:

npm install expo-horizon-location

#Important Limitation

Meta Quest devices don't have GPS hardware. Location is determined through:

• WiFi networks
• IP geolocation

This provides city or region-level accuracy at best.

#Use Cases

• Timezone detection
• Regional content defaults
• Analytics
• Light social features

#Example

import * as Location from 'expo-horizon-location';

async function getCurrentLocation() {
  const { status } = await Location.requestForegroundPermissionsAsync();
  if (status !== 'granted') {
    console.error('Permission denied');
    return;
  }

  const location = await Location.getCurrentPositionAsync();
  return location;
}

#Platform-Specific Logic

When writing cross-platform code, use platform detection:

import { Platform } from 'react-native';
import ExpoHorizon from 'expo-horizon-core';

function getPlatform() {
  if (ExpoHorizon.isHorizonDevice) {
    return 'horizon';
  }
  return Platform.OS;
}

Some libraries provide feature checks:

• expo-sms - Check SMS availability
• expo-sensors - Check sensor availability
