Verdict

The call

The clearest difference is review sentiment: DeFNCE at 100% against EMF Radiation Detector Reader's 53%. DeFNCE also leads on in-app purchases (none vs 2) and update cadence (every 4 weeks vs every 7 months). EMF Radiation Detector Reader's advantage is rating (4.5 vs 1.0) and ratings volume (4.7K vs 1). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

EMF Radiation Detector Reader holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: EMF Radiation Detector Reader has 4.7K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 53% of EMF Radiation Detector Reader's written reviews are positive against 100% of DeFNCE's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

EMF Radiation Detector Reader ships an update every 7 months, DeFNCE every 4 weeks. The most recent releases landed on October 15, 2026 and October 2, 2026 respectively.
