VinCheckUp holds the better App Store score, 4.2 against 3.1. Both are backed by a comparable volume of ratings — 41 and 20 respectively. Written reviews complicate that: 33% of VinCheckUp's written reviews are positive against 50% of Catalytic Converter Database's, so the app with the better star average is not the one people write more warmly about.
