Petkey holds the better App Store score, 4.8 against 3.5.

Written reviews complicate that: 51% of Maddie's Pet Assistant'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.
Maddie's Pet Assistant ships an update every 6 weeks, Petkey every 5 weeks. The most recent releases landed on October 24, 2026 and October 29, 2026 respectively.
