Listening Device Detector - LD

LD sweeps the room you are in and answers one question: what here can hear you? It checks the Wi-Fi network you are on, the Bluetooth around you, and the magnetic field, then gives you a report. Every device is named, classified and explained — not a needle on a dial you have to interpret. Everything runs on your phone. No account, no sign-up, nothing uploaded. WHAT A SWEEP FINDS Smart speakers and voice assistants. Echo, Nest, HomePod and the rest announce themselves on the network, and LD tells you which ones listen for a wake word. IP cameras and baby monitors. Anything streaming over RTSP or ONVIF is visible, and nearly all carry a microphone next to the lens. Bluetooth audio devices. Headsets, speakers and earbuds broadcasting nearby, including ones you never paired. Everything else on the network. Printers, computers and file shares are listed too, so every device is accounted for. EVERY FINDING EXPLAINS ITSELF Tap any device and LD shows what it actually broadcast, why that led to the conclusion, and what to do about it. A verdict you cannot check is not worth much. THE GUIDED ROOM SWEEP The devices a phone cannot see have to be found by looking, in the right places, in order. LD includes a step-by-step physical sweep: smoke detectors and ceiling fittings, anything with a plug, air vents, mirrors, the bedside area, the bathroom. WHAT NO APP CAN FIND, INCLUDING THIS ONE Read this before you trust a clean result. A covert bug transmitting on its own radio frequency sends on a band an iPhone has no receiver for. It is invisible to this app and to every other app - those are found with a dedicated RF detector, not a phone. A bug with a SIM card reports over the mobile network and broadcasts nothing. A recorder that only stores audio transmits nothing at all. A wired microphone is electrically silent from outside. Anything switched off is not there to be found. LD does not detect hidden cameras by their lens or infrared - that is a different technique. It finds cameras only when they are on the network. So a clean sweep means exactly one thing: nothing with a microphone answered on this network or over Bluetooth. It is not proof a room is clear, which is why the guided physical sweep exists. WHAT YOU GET FREE - Full sweep across network, Bluetooth and magnetic checks - The findings report, with every device named and classified - Device detail showing the evidence behind each conclusion - The hotel room guided sweep - The complete, honest list of what a phone cannot detect WHAT PRO ADDS - Guided sweeps for cars, offices and rental homes - History, so you can spot a device that was not there last time - Magnetic locator with a live proximity meter - Export a sweep report as CSV IF YOU THINK YOU ARE BEING MONITORED Contact the police. If you find a device, photograph it where it sits rather than handling it, and report it. In a rental, tell the platform too - an undisclosed indoor camera breaks most of their rules. LD is a tool for checking a room, not a substitute for the authorities. PRIVACY Sweeps stay on your device. No account, no analytics, nothing uploaded.
