react-native-app-usage-stats

React Native module for querying per-app foreground usage time on Android. Returns a graceful E_NOT_SUPPORTED error on iOS.

Platform Support

| Feature | Android | iOS | | ------------------------ | ------- | -------------- | | openUsageAccessSettings | Yes | Rejects E_NOT_SUPPORTED | | hasUsageAccess | Yes | Returns false | | getUsageByApps | Yes | Rejects E_NOT_SUPPORTED | | getUsageAllApps | Yes | Rejects E_NOT_SUPPORTED |

Why no iOS data? iOS does not expose per-app foreground usage time to third-party apps. The Screen Time APIs (FamilyControls / DeviceActivity) are restricted to managed device and parental control use cases with special entitlements.

Installation

npm install react-native-app-usage-stats
# or
yarn add react-native-app-usage-stats

iOS

cd ios && pod install

The iOS pod compiles but all data methods return E_NOT_SUPPORTED.

Android

No extra linking needed for RN >= 0.60 (autolinking).

Add the usage stats permission to your app's android/app/src/main/AndroidManifest.xml:

<manifest ...>
    <uses-permission
        android:name="android.permission.PACKAGE_USAGE_STATS"
        tools:ignore="ProtectedPermissions"
        xmlns:tools="http://schemas.android.com/tools" />
    ...
</manifest>

Important: PACKAGE_USAGE_STATS is a special permission. It cannot be requested at runtime via a dialog. The user must manually grant it in Settings > Apps > Special access > Usage access. Use openUsageAccessSettings() to navigate the user there.

OEM Quirks

• Samsung / Xiaomi / Huawei: Some OEMs restrict background data collection. If getUsageByApps returns 0 for all apps despite permission being granted, advise users to also disable battery optimization for your app.
• Android 10+: Uses appOpsManager.unsafeCheckOpNoThrow() for permission checks (handled automatically by the module).

API

import {
  openUsageAccessSettings,
  hasUsageAccess,
  getUsageByApps,
  getUsageAllApps,
} from 'react-native-app-usage-stats';

openUsageAccessSettings(): Promise<void>

Opens the system Usage Access settings screen. Android only.

hasUsageAccess(): Promise<boolean>

Returns true if the app has usage stats permission. iOS always returns false.

getUsageByApps(packageNames: string[], days: number): Promise<AppUsageRecord[]>

Returns foreground usage for the specified packages over the last days days (including today).

const data = await getUsageByApps(
  ['com.instagram.android', 'com.twitter.android'],
  7
);
// [
//   { trackId: 'com.instagram.android', usage: 3600, date: '2026-03-06' },
//   { trackId: 'com.twitter.android',   usage: 1200, date: '2026-03-06' },
//   { trackId: 'com.instagram.android', usage: 2400, date: '2026-03-05' },
//   ...
// ]

getUsageAllApps(days: number): Promise<DailyUsageReport[]>

Returns foreground usage for ALL apps over the last days days.

const reports = await getUsageAllApps(3);
// [
//   {
//     date: '2026-03-06',
//     data: [
//       { trackId: 'com.instagram.android', usage: 3600 },
//       { trackId: 'com.android.chrome',    usage: 7200 },
//     ]
//   },
//   ...
// ]

Types

interface AppUsageRecord {
  trackId: string;   // package name
  usage: number;     // seconds
  date: string;      // YYYY-MM-DD
}

interface DailyUsageReport {
  date: string;
  data: Array<{ trackId: string; usage: number }>;
}

Error Codes

| Code | When | | -------------------- | ----------------------------------------- | | E_PERMISSION_DENIED | Usage access not granted (Android) | | E_NOT_SUPPORTED | Called a data method on iOS | | E_UNKNOWN | Unexpected error |

Compatibility

• React Native >= 0.71
• Android minSdkVersion 21 (Android 5.0+)
• iOS 13+ (compiles; returns E_NOT_SUPPORTED for data)

Example Usage

import React, { useEffect, useState } from 'react';
import { View, Text, Button, Platform, Alert } from 'react-native';
import {
  openUsageAccessSettings,
  hasUsageAccess,
  getUsageByApps,
} from 'react-native-app-usage-stats';

export default function App() {
  const [hasAccess, setHasAccess] = useState(false);
  const [usage, setUsage] = useState<any[]>([]);

  useEffect(() => {
    hasUsageAccess().then(setHasAccess);
  }, []);

  const fetchUsage = async () => {
    try {
      const data = await getUsageByApps(
        ['com.instagram.android', 'com.android.chrome'],
        7
      );
      setUsage(data);
    } catch (e: any) {
      Alert.alert('Error', e.message);
    }
  };

  return (
    <View style={{ flex: 1, padding: 20, paddingTop: 60 }}>
      <Text>Permission: {hasAccess ? 'Granted' : 'Not granted'}</Text>

      {!hasAccess && Platform.OS === 'android' && (
        <Button
          title="Grant Usage Access"
          onPress={openUsageAccessSettings}
        />
      )}

      {hasAccess && (
        <Button title="Fetch 7-day usage" onPress={fetchUsage} />
      )}

      {usage.map((item, i) => (
        <Text key={i}>
          {item.date} | {item.trackId} | {Math.round(item.usage / 60)} min
        </Text>
      ))}
    </View>
  );
}
