Verdict
The clearest difference is price: CorePendium at Free against EyesHaveIt's $4.99. CorePendium also leads on rating (4.9 vs 3.8) and update cadence (monthly vs every 6 months). EyesHaveIt's advantage is review sentiment (80% vs 67%) and iOS requirement (6.0 vs 15.1). On ads, in-app purchases and device support there is nothing between them.

CorePendium is free to download; EyesHaveIt costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.
CorePendium holds the better App Store score, 4.9 against 3.8. That said, the two scores are not equally well evidenced: CorePendium has 1.4K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 80% of EyesHaveIt's written reviews are positive against 67% of CorePendium's, so the app with the better star average is not the one people write more warmly about.
EyesHaveIt ships an update every 6 months, CorePendium monthly. Both last shipped on September 28, 2026.
