What does the "Find My" app require to function correctly?

The "Find My" app requires location services to be enabled in order to function correctly. This is because the app relies on GPS and other location technology to determine the current physical location of the Apple device. When location services are active, the app can pinpoint the device's whereabouts, allowing users to find lost items or devices. This functionality is fundamental to the "Find My" app, as it cannot provide the device's location without access to accurate location data.

While having an active iCloud account is also necessary for the app to track devices, enabling location services is the essential step for real-time location tracking to function effectively. The other aspects like Bluetooth connectivity and biometric security features like Face ID or Touch ID are useful but not central to the app's primary location tracking capability. Thus, enabling location services is critical for the app to perform its main task.
