ReceptionRating · Positive reviews · Number of ratings

OnStar Guardian holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: OnStar Guardian has 23K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 32% of OnStar Guardian's written reviews are positive against 100% of OmniSecure by SiriusXM Connect's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

OnStar Guardian ships an update every 5 weeks, OmniSecure by SiriusXM Connect monthly. The most recent releases landed on September 24, 2026 and September 18, 2026 respectively.
