ReceptionRating · Positive reviews · Number of ratings

Expression Guest Registry™ holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Petkey has 823 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Expression Guest Registry™'s written reviews are positive against 44% of Petkey's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Expression Guest Registry™ ships an update every 2 months, Petkey every 5 weeks. The most recent releases landed on October 6, 2026 and October 16, 2026 respectively.
