Hi CrypticThread, there are several ways to accomplish this.
One option is to use Google’s native device locating service, which can be accessed from any web browser on an iPhone.
Another method involves using cross-platform family safety apps. These are designed to share location between Android and iOS devices, though some may require initial setup on the Android phone.
For more discreet tracking, you could look into a spy app. This type of application is installed on the Android device and is designed to run in the background, reporting its location to a web dashboard that you can view from your iPhone.
You can research these categories to find a solution that fits your specific requirements.
