ReceptionRating · Positive reviews · Number of ratings

Device System Services holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Device System Services has 392 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of atCompassMobile's written reviews are positive against 52% of Device System Services's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

atCompassMobile ships an update every 6 months, Device System Services every 4 months. The most recent releases landed on November 1, 2026 and November 6, 2026 respectively.
