CorePendium holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: CorePendium has 1.5K ratings behind it against 78, so its average is the more settled of the two. Written reviews complicate that: 91% of thumbroll's written reviews are positive against 62% of CorePendium's, so the app with the better star average is not the one people write more warmly about.
