Could you build this?

Partial Building an iOS app that taps into private IOKit/IOPS/SMC APIs to extract low-level hardware telemetry requires reverse-engineering undocumented Apple private frameworks.

What it would actually take: The app requires finding, dynamically linking, and calling undocumented private Apple frameworks (such as IOHIDFamily, IOKit, and AppleSMC/CoreCapture) in Objective-C or Swift. While the UI is simple to vibe-code, discovering the exact private keys, struct layouts, and handling entitlements/jailbreak or sideloading restrictions requires reverse engineering iOS dyld caches and firmware dumps.
