ReceptionRating · Positive reviews · Number of ratings

Device Detector holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Device Detector has 3.6K ratings behind it against 69, so its average is the more settled of the two. Written reviews complicate that: 49% of Device Detector's written reviews are positive against 66% of EMF Analytics's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Device Detector ships an update monthly, EMF Analytics every 2 days. The most recent releases landed on October 1, 2026 and September 28, 2026 respectively.
