Airprowl shows every wireless device around you in one live terminal view: Bluetooth (classic and BLE), WiFi access points and the clients talking to them, and Sub-GHz devices on 315, 433, 868 and 915 MHz through a Yard Stick One.
Each device gets a smoothed signal reading with a trend arrow, a rough distance estimate and a vendor name from bundled IEEE and Bluetooth SIG databases. WiFi scanning works without root; watching WiFi clients uses a monitor interface and parses the raw 802.11 frames.
There's also a headless mode that streams JSON, and a demo mode with simulated devices, which is what the recording above shows.
