# Atom Radiometer vs EMF Detector

The clearest difference is rating: EMF Detector at 4.3 against Atom Radiometer's 3.7. EMF Detector also leads on ratings volume (319 vs 9). Atom Radiometer's advantage is in-app purchases (none vs 3) and review sentiment (54% vs 25%). On price, update cadence, 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. Atom Radiometer asks for nothing beyond the download.

EMF Detector holds the better App Store score, 4.3 against 3.7. That said, the two scores are not equally well evidenced: EMF Detector has 319 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 54% of Atom Radiometer'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.

Atom Radiometer ships an update monthly, EMF Detector every 2 weeks. The most recent releases landed on September 27, 2026 and September 30, 2026 respectively.
