# Eye Chart Pro vs Smart Optometry

The clearest difference is rating: Smart Optometry at 4.4 against Eye Chart Pro's 4.0. Smart Optometry also leads on ratings volume (529 vs 2) and device support (3 vs 1). Eye Chart Pro's advantage is review sentiment (53% vs 42%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Eye Chart Pro sells 11 one-off in-app purchases and Smart Optometry sells 10 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Smart Optometry holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Smart Optometry has 529 ratings behind it against 2, 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 42% of Smart Optometry'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, Smart Optometry every 4 months. The most recent releases landed on July 27, 2026 and September 20, 2026 respectively.
