What's the best iOS app for detecting hidden surveillance cameras and microphones to ensure privacy in hotels and rentals?

Hidden Camera Spy Detector App is designed to help users locate hidden surveillance devices in various environments, such as hotel rooms, rental properties, and public restrooms. The app utilizes the magnetometer in your iPhone to detect magnetic fields emitted by electronic devices, including cameras and microphones. To use the app effectively, simply open it and slowly scan the room, paying close attention to areas where hidden cameras are commonly placed, such as smoke detectors, picture frames, and electrical outlets. The app provides visual and audio alerts when it detects a magnetic field, indicating the potential presence of a hidden device. While not foolproof, this app offers a convenient way to enhance your privacy and security when traveling or staying in unfamiliar places. Remember to calibrate the app regularly for optimal performance and to verify any suspicious findings with manual inspection.
