# Radiation Scan Pro vs EMF Detector

The clearest difference is rating: EMF Detector at 4.3 against Radiation Scan Pro's 3.2. EMF Detector also leads on update cadence (every 2 weeks vs every 3 months) and ratings volume (319 vs 16). Radiation Scan Pro's advantage is in-app purchases (none vs 3) and review sentiment (52% vs 25%). On price, ads and device support there is nothing between them.

Both are free to download. EMF Detector sells 2 in-app purchases, starting at $4.99 per month. Radiation Scan Pro asks for nothing beyond the download.

EMF Detector holds the better App Store score, 4.3 against 3.2. That said, the two scores are not equally well evidenced: EMF Detector has 319 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 52% of Radiation Scan Pro'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.

Radiation Scan Pro ships an update every 3 months, EMF Detector every 2 weeks. Both last shipped on October 13, 2026.
