Check a place
An Airbnb, a hotel room, an office. It names the speakers, displays, cameras and robot vacuums on the Wi-Fi by model, finds the cheap hidden cameras that answer a tell-tale question, and walks you through the seventeen places a camera hides.
Wi-Fi and Bluetooth
On a date
Camera glasses and AI recorders give themselves away over Bluetooth when they switch on, pair or come out of the case. It names the ones nearby and keeps listening if you leave it on the table. Meta glasses go silent once connected, so a quiet table isn't proof.
Can see or hear you
Being tracked?
AirTags and other Find My items, Samsung, Tile, Chipolo and Google tags, which of them say they're away from their owner, and the same device turning up where you go on different days.
Can follow you
Card reader
At a gas pump it listens for the newer Bluetooth parts skimmers are built from and follows the signal from pump to pump. Most skimmers found so far use older Bluetooth an iPhone can't hear, so it can't clear a pump.
Skimmer parts
Plate readers
The Flock and other license plate cameras mapped across the US and Canada, spoken alerts before each one on the road, and routes that pass fewer of them.
On the road
Overhead
Drones broadcasting their Remote ID, with where the pilot is standing, and the planes and helicopters above you, including which ones the FAA lists as government owned and which are circling.

Who's on my Wi-Fi?
Every device on your own network by name, what each one can see or hear, and what's new since you last looked. A security check flags a camera that opened a door to the internet and shows what anyone scanning your address from outside would find. A speed test, DNS comparison, ping, port scan and Wake on LAN are built in. Your names, rooms and notes stay on your phone.
