Simply press a button to randomize the entire eye chart, or touch an individual line of the chart to randomize that line. Swipe right for the chart selector. Eye care professionals around the world use Snellen Eye Charts to measure visual acuity. However, patients often memorize the classic Snellen chart, leading to less accurate vision measurements. Enter EyeChart! Though this unique, pocket-sized randomizable eye chart should not be used as a primary visual acuity measuring tool, it can provide a handy rough vision screen when a chart is not available, or it can be used to complement static, wall-based Snellen charts.

The subscription costs $0.99 per month of access, and is available through an auto-renewing subscription which will renew each month for your convenience until you choose to turn it off.

Verdict

The call

The clearest difference is rating: Smart Optometry at 4.4 against EyeChart's 2.8. Smart Optometry also leads on ratings volume (530 vs 17) and update cadence (every 4 months vs every 9 months). EyeChart's advantage is iOS requirement (7.0 vs 13). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. EyeChart sells 1 in-app purchase, starting at $0.99 per month 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.

ReceptionRating · Positive reviews · Number of ratings

Smart Optometry holds the better App Store score, 4.4 against 2.8. That said, the two scores are not equally well evidenced: Smart Optometry has 530 ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 45% of EyeChart'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.

UpkeepUpdate frequency

EyeChart ships an update every 9 months, Smart Optometry every 4 months. The most recent releases landed on November 3, 2026 and November 6, 2026 respectively.
