# Hidden Camera Detector vs EMF Radiation Detector

The clearest difference is in-app purchases: EMF Radiation Detector at none against Hidden Camera Detector's 2. EMF Radiation Detector also leads on review sentiment (54% vs 21%) and iOS requirement (7.1 vs 15.6). Hidden Camera Detector's advantage is rating (3.6 vs 3.4) and ratings volume (1.8K vs 200). On price, ads and device support there is nothing between them.

Both are free to download. Hidden Camera Detector sells 2 in-app purchases, starting at $9.99 per month. EMF Radiation Detector asks for nothing beyond the download.

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.
