# Lab Values Pro vs Eye Charts

The clearest difference is review sentiment: Eye Charts at 68% against Lab Values Pro's 0%. Eye Charts also leads on update cadence (every 2 months vs every 10 months) and ratings volume (29 vs 3). Lab Values Pro's advantage is rating (4.0 vs 3.5) and price ($0.99 vs $4.99). On ads, in-app purchases and device support there is nothing between them.

Lab Values Pro costs $0.99 and Eye Charts $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Lab Values Pro holds the better App Store score, 4.0 against 3.5. That said, the two scores are not equally well evidenced: Eye Charts has 29 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 0% of Lab Values Pro's written reviews are positive against 68% of Eye Charts's, so the app with the better star average is not the one people write more warmly about.

Lab Values Pro ships an update every 10 months, Eye Charts every 2 months. The most recent releases landed on October 6, 2026 and October 18, 2026 respectively.
