This library is currently in alpha and will frequently experience breaking changes.

expo-age-range provides access to user age range information. It uses Google's Play Age Signals API on Android and Apple's Declared Age Range framework on iOS.

This library allows you to request age range information from your app users to help you comply with age-appropriate content regulations (such as in Texas, USA) and provide age-appropriate experiences in your app.

Limitations

We strongly recommend testing the functionality on a real device, as simulator runtimes may not work as expected.

Installation

If you are installing this in an existing React Native app, make sure to install expo in your project.

Configuration in app config

Setup iOS project

To use the age range API on iOS, you need to build your project with Xcode 26.0 or later. The com.apple.developer.declared-age-range entitlement is required. Add it to your app config file:

{
  "expo": {
    "ios": {
      "entitlements": {
        "com.apple.developer.declared-age-range": true
      }
    }
  }
}

<key>com.apple.developer.declared-age-range</key>
<true/>

Usage

import * as AgeRange from 'expo-age-range';
import { useState } from 'react';
import { StyleSheet, Text, View, Button } from 'react-native';

export default function App() {
  const [result, setResult] = useState<AgeRange.AgeRangeResponse | { error: string } | null>(null);

  const requestAgeRange = async () => {
    try {
      const ageRange = await AgeRange.requestAgeRangeAsync({
        threshold1: 10,
        threshold2: 13,
        threshold3: 18,
      });
      setResult(ageRange);
    } catch (error) {
      setResult({ error: error.message });
    }
  };

  return (
    <View style={styles.container}>
      <Button title="Request Age Range" onPress={requestAgeRange} />
      {result && (
        <Text style={styles.result}>
          {'error' in result ? `Error: ${result.error}` : `Lower age bound: ${result.lowerBound}`}
        </Text>
      )}
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    padding: 20,
  },
  result: {
    marginTop: 20,
    fontSize: 16,
  },
});
