HOW IT WORKS • IR / Reflection Camera — spot bright lens reflections that may hide a camera. • Magnetic Anomaly Detector — calibrates a baseline, then alerts on magnetic spikes near electronics. • Bluetooth Scanner — finds nearby wireless devices with live signal strength (hot/cold). • Network Scanner — lists devices on your Wi-Fi, like IP cameras and smart gadgets. KEY FEATURES • Instant sound + vibration alert • Live proximity meter — get closer, signal gets stronger • Magnetic alarm with baseline calibration • Scan history with a simple risk score • Step-by-step manual inspection guide • Works fully on-device — nothing is uploaded • No account, no sign-up PERFECT FOR Hotels, Airbnb & rentals, changing rooms, restrooms, offices, and anyone who values their privacy.

SONAR: HIDDEN CAMERA AND TRACKER DETECTOR Sonar helps you check for hidden cameras, hidden microphones, and Bluetooth/Wi-Fi trackers, a privacy inspection support tool with infrared, Wi-Fi network, and Bluetooth scanning. Whether you're in a motel room, hotel, Airbnb, locker room, public restroom, fitting room, car, or your own luggage, Sonar helps you inspect the space in minutes. IMPORTANT: no phone app can guarantee with certainty that a space is free of hidden cameras. Sonar is a support tool, each finding comes with a confidence level so you can physically check the spot it flags. Always use it alongside a manual inspection. DETECTOR FEATURES Infrared scanner Point your phone's camera and look for the telltale reflection of hidden spy camera lenses, a common sign in cameras disguised as a button camera, pen camera, charger, smoke detector, or clock. Works best in a dark room and doesn't replace a physical check. Wi-Fi network and Bluetooth device detection Sonar scans the local Wi-Fi network and nearby Bluetooth devices to flag devices with characteristics of connected cameras or trackers. Each result shows a confidence level, not a definitive confirmation. Bluetooth tracker detector Flags signals from Bluetooth trackers nearby: in your car, bag, luggage, or personal belongings, as support against unwanted tracking during travel and everyday life. Guided sweep A practical checklist walks you through spots where cameras and microphones are commonly hidden: outlets, smoke detectors, picture frames, mirrors, chargers, clocks, and more, so you can physically inspect each one.
