Apple says it has worked with Google to create an industry specification that can alert users across both iOS and Android if a Bluetooth tracking device is being used to track them (also known as Bluetooth Stalking). 

The new capability, which is being implemented in Apple’s new iOS 17.5 (and on Android 6.0+ devices) will deliver an “[Item] Found Moving With You” alert on those devices if an unknown Bluetooth tracking device is seen moving with them over time, regardless of the platform the device is paired with.  

Apple says this will “help mitigate the misuse of devices designed to help keep track of belongings.” For example, if a user receives the alert on their iOS device, it means that someone else’s AirTag, Find My accessory, or other industry specification-compatible Bluetooth tracker is moving with them.
