# Metal Detector EMF vs Magnetometer

Metal Detector EMF also leads on ratings volume (2.4K vs 13) and update cadence (every 7 months vs every 34 months). Magnetometer's advantage is in-app purchases (none vs 1) and review sentiment (86% vs 71%). On ads there is nothing between them.

Metal Detector EMF is free to download; Magnetometer costs $0.99 up front. Metal Detector EMF sells 1 one-off in-app purchase. Magnetometer asks for nothing beyond the download.

Metal Detector EMF holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Metal Detector EMF has 2.4K ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 71% of Metal Detector EMF's written reviews are positive against 86% of Magnetometer's, so the app with the better star average is not the one people write more warmly about.

Metal Detector EMF ships an update every 7 months, Magnetometer every 34 months. The most recent releases landed on September 23, 2026 and September 7, 2026 respectively.
