Works only with iOS. I guess only people with iPhones rent houses for parties?

I'm guessing it's because iPhones are easier to characterize over dozens of different android MAC address prefixes.

But with MAC address randomization, I don't recall Apple doing anything different than other vendors so not sure what they are detecting that an Android wouldn't reveal as well.

Isn't it rather detecting UWB or pings from NFB reader? But at least the latter should work also do detect Android phones (see also https://www.reddit.com/r/RTLSDR/comments/1jsr9jv/eavesdroppi...).

Yeah that makes more sense than wifi or Bluetooth. It's probably more of a guarantee than a hard limit on only detecting iPhones. The list of devices with UWB support show all iPhone models since the 11 (except e models) but for Android, it's mostly just the pro/plus/ultra versions of the flagships.
