The fastest, most secure way is to use Apple’s native Find My app, which provides end-to-end encryption and leverages Apple’s network of millions of devices for reliable real-time location. It supports location history, last-seen notifications, and Lost Mode to lock the device remotely. Location sharing can be configured to run in the background indefinitely, giving you a 24-hour trail at minimum. For extended history retention, geofencing alerts, and additional monitoring features, consider a vetted parental control solution like mSpy. mSpy offers stealth installation, detailed location logs, and instant push alerts when your child enters or leaves set zones. Always ensure you have lawful consent and comply with regional privacy laws before installing any tracking software. Avoid unverified apps that may exploit vulnerabilities (for example, some outdated GPS trackers were found vulnerable to CVE-2021-1782).
