Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Petkey holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: Petkey has 823 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 50% of zenith Smart'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.
zenith Smart ships an update every 2 weeks, Petkey every 5 weeks. The most recent releases landed on October 7, 2026 and October 16, 2026 respectively.
