Checking into a hotel or Airbnb? Sweep the room in about two minutes before you unpack. Faraday turns your iPhone into a privacy scanner: find hidden cameras, spot Bluetooth trackers that may be following you, and see exactly who's connected to your Wi-Fi. We'll tell you the honest truth up front — no phone can catch everything, and we show you what each scan can and can't detect. That's the difference between Faraday and the apps that overpromise. WHAT FARADAY DOES • Hidden Camera Detector — scan your Wi-Fi for connected devices and possible IP cameras, and use your camera to catch tell-tale lens reflections and infrared LEDs. • AirTag & Tracker Detector — sweep for nearby Bluetooth trackers and flag the ones that look like they're traveling with you. • Who's On My Wi-Fi — see every device on the network, with unknown devices called out. Plus a built-in Wi-Fi safety check and speed test. • Continuous Background Monitoring — keep watching your Wi-Fi after you close the app and get an alert when a new device appears. • Bug Detector — use the magnetometer to sense magnetic fields from some hidden electronics. • Room Sweep Presets — one tap runs the whole sequence for where you are: Hotel, Airbnb, Home or Car. BUILT FOR PRIVACY Faraday runs entirely on your device. No account. No sign-in. No third-party tracking. Your scan results never leave your iPhone. FARADAY PRO Upgrade for unlimited scans, background monitoring with new-device alerts, full scan history, and complete room-sweep reports. Available as a weekly, monthly, or annual subscription, or as a one-time Lifetime purchase with no subscription. Each subscription starts with a free trial. HONEST ABOUT LIMITS A phone can't do professional RF detection, and no scan is guaranteed to find every device. Faraday helps you check the most common risks quickly and tells you plainly where its limits are. Travel a little safer. Questions?
