EMF Detector holds the better App Store score, 4.3 against 4.1. That said, the two scores are not equally well evidenced: EMF Detector has 319 ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 70% of GMCMap's written reviews are positive against 25% of EMF Detector's, so the app with the better star average is not the one people write more warmly about.
GMCMap ships an update every 5 months, EMF Detector every 2 weeks. The most recent releases landed on September 22, 2026 and September 21, 2026 respectively.
