# Electromagnetic EMF Detector vs Metal Detector

The clearest difference is price: Metal Detector at Free against Electromagnetic EMF Detector's $1.99. Electromagnetic EMF Detector's advantage is ads (none vs shown) and update cadence (every 5 weeks vs every 7 months). On rating, review sentiment, ratings volume and in-app purchases there is nothing between them.

Metal Detector is free to download; Electromagnetic EMF Detector costs $1.99 up front. Electromagnetic EMF Detector sells 2 one-off in-app purchases and Metal Detector sells 6 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Metal Detector holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 212 and 415 respectively. Written reviews complicate that: 79% of Electromagnetic EMF Detector's written reviews are positive against 78% of Metal Detector's, so the app with the better star average is not the one people write more warmly about.

Electromagnetic EMF Detector ships an update every 5 weeks, Metal Detector every 7 months. The most recent releases landed on October 22, 2026 and October 30, 2026 respectively.
