Both are free to download. EMF Detector sells 2 in-app purchases, starting at $4.99 per month. Radex asks for nothing beyond the download.
EMF Detector holds the better App Store score, 4.3 against 2.3. That said, the two scores are not equally well evidenced: EMF Detector has 319 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 25% of EMF Detector's written reviews are positive against 33% of Radex's, so the app with the better star average is not the one people write more warmly about.
EMF Detector ships an update every 2 weeks, Radex every 2 months. The most recent releases landed on October 13, 2026 and September 29, 2026 respectively.
