react-native-device-activity

Provides access to Apples DeviceActivity API. It does require a Custom Dev Client to work with Expo.

Please note that it only supports iOS (and requires iOS 15 or higher). For Android I'd probably look into UsageStats, which seems provide more granularity.

Examples

import * as ReactNativeDeviceActivity from "react-native-device-activity";

const DeviceActivityPicker = () => {
  // First things first, you need to request authorization
  useEffect(() => {
    ReactNativeDeviceActivity.requestAuthorization()
  }, [])

  const [familyActivitySelection, setFamilyActivitySelection] = React.useState(null);

  // next you need to present a native view to let the user select which activities to track, you need to do this before you can start tracking (this is a completely unstyled clickable native view):
  return (
    <ReactNativeDeviceActivity.DeviceActivitySelectionView
      onSelectionChange={(event) => {
        setFamilyActivitySelection(
          event.nativeEvent.familyActivitySelection
        )
      }}
      familyActivitySelection={familyActivitySelection}>
        <Text>Click here</Text>
    </ReactNativeDeviceActivity.DeviceActivitySelectionView>)
  }
}

// once you have authorization and got hold of the familyActivitySelection (which is a base64 string) you can start tracking with it:
const trackDeviceActivity = (activitySelection: string) => {
  ReactNativeDeviceActivity.startMonitoring(
    "DeviceActivity.AppLoggedTimeDaily",
    {
      // repeat logging every 24 hours
      intervalStart: { hour: 0, minute: 0, second: 0 },
      intervalEnd: { hour: 23, minute: 59, second: 59 },
      repeats: true,
    },
    events: [
      {
        eventName: 'user_activity_reached_10_minutes',
        familyActivitySelection: activitySelection,
        threshold: { minute: 10 },
      }
    ]
  );
}

// you can listen to events (which I guess only works when the app is alive):
const listener = ReactNativeDeviceActivity.onDeviceActivityMonitorEvent(
      (event) => {
        const name = event.nativeEvent.callbackName; // the name of the event
        /* callbackName is one of, corresponding to the events received from the native API:
          - "intervalDidStart"
          - "intervalDidEnd"
          - "eventDidReachThreshold"
          - "intervalWillStartWarning"
          - "intervalWillEndWarning"
          - "eventWillReachThresholdWarning";
        */
      }
    );

// you can also get a history of events called with the time where called:
const events = ReactNativeDeviceActivityModule.getEvents();

Installation in managed Expo projects

For managed Expo projects, please follow the installation instructions in the API documentation for the latest stable release. If you follow the link and there is no documentation available then this library is not yet usable within managed projects — it is likely to be included in an upcoming Expo SDK release.

The package requires native code, which includes a custom app target. Currently it requires targeting iOS 15 or higher, so populate app.json/app.config.json as follows:

"plugins": [
    [
      "expo-build-properties",
      {
        "ios": {
          "deploymentTarget": "15.0"
        },
      },
    ],
    [
      "react-native-device-activity",
      {
        "appleTeamId": "<YOUR_TEAM_ID>",
      }
    ]
  ],

The Swift files for the iOS target will be copied to your local /targets directory. You might want to add it to your .gitignore.

⚠️ Please note that you need to apply to apply to use this API before launching it in AppStore

Installation in bare React Native projects

For bare React Native projects, you must ensure that you have installed and configured the expo package before continuing.

Add the package to your npm dependencies

npm install react-native-device-activity

Configure for iOS

Run npx pod-install after installing the npm package.
