Easy to use, clinically evaluated visual acuity screening app. Over 1M people have downloaded our mobile electronic eye charts for iOS. Read below for more information on the clinical evaluations. Useful for: - Triaging - House visits - Hospital rounds - Emergency rooms - Schools - Patients who have memorized the office chart Eye Chart HD is a pocket vision screener: randomized Snellen, Tumbling E, and other charts to offer a rough but useful screen of visual acuity. 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 Eye Chart HD! 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. Subscription: In addition to our free features, Eye Chart HD offers a subscription to exclusive paid features, including the Randomizable Near Vision Chart, Line Isolation, Amsler Grid, and Single Optotype Charts! The subscription costs $2.99 per month of access and has to be purchased specially within the app. Once purchased, it is available through an auto-renewing subscription which will renew each month for your convenience until you choose to turn it off. Please let us know if you have any questions about your subscription at eyechartapp@gmail.com. Below is further information on clinical evaluations that have been done. Please do check out the papers cited below if you have concerns. We didn't do these tests and can't speak to them, but we are providing them here for transparency and your reference: Snellen & Tumbling E charts on Eye Chart HD on iPhone: “Comparison of Visual Acuity Measurement Using Three Methods: Standard ETDRS Chart, Near Chart and a Smartphone-Based Eye Chart Application” Clinical Ophthalmology. Conclusion: “VA measurements with the Near Chart and smartphone-based Eye Chart application corresponded well to the standard ETDRS chart, suggesting potential utility of alternative portable VA tests for in-office or remote vision monitoring, particularly during periods of physical distancing such as the Coronavirus disease 2019 (COVID-19) era” Sloan Chart on Eye Chart HD on iPhone: “Does the EyeChart App for iPhones Give Comparable Measurements to Traditional Visual Acuity Charts?” The British and Irish Orthoptic Journal. Conclusion: “This study found that the VA scores achieved on the EyeChart app are comparable to those achieved using the gold-standard ETDRS chart in a healthy young adult population. This is a promising finding; however, it is necessary for further large-scale studies to investigate the EyeChart app when used on a variety of patient population groups.” Snellen Chart on Eye Chart HD on iPad Mini: “Comparative Study of the Snellen iPad App versus Traditional Light Box Snellen Chart in Distance Visual Acuity” International Journal of Ophthalmology and Clinical Research. Conclusion: “It showed that the results from Eye Chart HD app used in an iPad Mini 2 agreed with the results of the traditional light-box Snellen Chart when used at the Outpatient Department.“ Rapid Vision Screening Chart on Eye Chart HD on iPhone/iPod: “Assessment of a rapid method to determine approximate visual acuity in large surveys and other such settings.” American Journal of Ophthalmology. Conclusion: “An iPod application requiring about a 1-minute testing time provides an objective, portable, rapid, and low-cost method to determine approximate VA, allowing VA testing to be performed efficiently in large surveys and other settings where approximate VA should be measured.”

Verdict
The clearest difference is rating: Eye Chart HD at 4.4 against Shift Admin's 3.3. Eye Chart HD also leads on iOS requirement (12.0 vs 15.1). Shift Admin's advantage is in-app purchases (none vs 2) and ads (none vs shown). On price, review sentiment and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Eye Chart HD sells 2 in-app purchases, starting at $2.99 per month. Shift Admin asks for nothing beyond the download.
Eye Chart HD holds the better App Store score, 4.4 against 3.3. That said, the two scores are not equally well evidenced: Shift Admin has 71 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 33% of Eye Chart HD's written reviews are positive against 35% of Shift Admin's, so the app with the better star average is not the one people write more warmly about.
Eye Chart HD ships an update every 6 months, Shift Admin every 2 months. The most recent releases landed on October 20, 2026 and October 15, 2026 respectively.
