# Eye Chart Pro vs Colorblind Eye Exam Test

The clearest difference is rating: Eye Chart Pro at 4.3 against Colorblind Eye Exam Test's 3.7. Eye Chart Pro also leads on update cadence (every 3 months vs every 6 months) and iOS requirement (12.0 vs 17.0). Colorblind Eye Exam Test's advantage is ratings volume (310 vs 3) and review sentiment (66% vs 53%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Eye Chart Pro sells 10 one-off in-app purchases and Colorblind Eye Exam Test sells 5 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

Eye Chart Pro holds the better App Store score, 4.3 against 3.7. That said, the two scores are not equally well evidenced: Colorblind Eye Exam Test has 310 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 53% of Eye Chart Pro's written reviews are positive against 66% of Colorblind Eye Exam Test's, so the app with the better star average is not the one people write more warmly about.

Eye Chart Pro ships an update every 3 months, Colorblind Eye Exam Test every 6 months. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
