# EyeQue PDCheck vs Opthy

The clearest difference is rating: Opthy at 4.5 against EyeQue PDCheck's 3.6. Opthy also leads on ads (none vs shown) and ratings volume (2.9K vs 130). EyeQue PDCheck's advantage is review sentiment (31% vs 13%) and iOS requirement (12.0 vs 14.0). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Opthy holds the better App Store score, 4.5 against 3.6. That said, the two scores are not equally well evidenced: Opthy has 2.9K ratings behind it against 130, so its average is the more settled of the two. Written reviews complicate that: 31% of EyeQue PDCheck's written reviews are positive against 13% of Opthy's, so the app with the better star average is not the one people write more warmly about.

EyeQue PDCheck ships an update every 3 weeks, Opthy monthly. The most recent releases landed on August 24, 2026 and September 29, 2026 respectively.
