ReceptionRating · Positive reviews · Number of ratings

Hidden Camera Detector holds the better App Store score, 3.6 against 3.4. That said, the two scores are not equally well evidenced: Hidden Camera Detector has 1.8K ratings behind it against 200, so its average is the more settled of the two. Written reviews complicate that: 21% of Hidden Camera Detector's written reviews are positive against 54% of EMF Radiation Detector's, so the app with the better star average is not the one people write more warmly about.
