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. Clear, straightforward results See the confidence level of each finding, with real-time visual indication, no technical jargon.

Verdict
The clearest difference is in-app purchases: Sonar at none against Serial Box's 1. Serial Box's advantage is iOS requirement (14.0 vs 16.4). On price, update cadence, ads and device support there is nothing between them.
