The most accurate, advanced visual acuity screening app for iPhone and iPod Touch. Over 1,000,000 people have downloaded our mobile electronic eye charts for iOS. This version is our best for iPhone, and it's now completely free. Useful for: - Triaging - House visits - Patients who have memorized the office chart Features: - Randomizable Snellen Chart - Randomizable Tumbling E Chart - Randomizable Sloan Letters Chart - Randomizable Landolt C Chart - Randomizable Near Vision Chart (w/subscription) - Line Isolation (w/subscription) - Amsler Grid (w/subscription) - Single optotype charts (w/subscription) Description: Eye Chart HD is a pocket vision screener: randomized Snellen, Sloan, Tumbling E, and Landolt C 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. Check out our Terms of Use and Privacy Policy at eyechartproapp.com/termsofuse. Eye Chart HD was made with the best of intentions, and we hope to continue improving it. Your feedback is appreciated!



  • Awful

    By Sphingosaurus
    Have to register who you are, what your profession is, every time you open the app. Makes it useless in a professional setting
  • Painful

    By Nicholasname124
    I have to register every time I open the app. What a pain
  • Stopped working in iOS 8.

    By Wheresnaldo
    Support website does not exist and app is nonfunctional frozen on the first screen. Need a new app now :(
  • Orphaned App

    By Desert Samurai
    Another orphaned app. No updates in a while.
  • Where is the mirror button?

    By CRSlack
    When I did the explore option it said there was a mirror feature so I paid for the upgrade--no mirror feature.
  • Essential for residents

    By JABtertius
    I am a neurology resident and when seeing patients in clinic and in the emergency department, there is generally no chart available to test visual acuity. Even if you are lucky enough to have a pocket card, the patient already knows what the letters are after you have tested the first eye, biasing the results of the second eye exam. This program eliminates all of these difficulties. My iPhone is always on my person so I can easily whip it out and check visual acuity and with the randomization feature, the patient has unique combination of letters each time.
  • Excellent but a few caveats & suggestions

    By Sliv99
    Make sure you turn the brightness setting to max. This greatly impacts the score. The instructions should mention this The Ishi Hari is a great addition. I would like the plates numbered and an interpretation available. I would be willing to pay a little more for a few more plates With these changes, this would be 5-star. A great App.

    This app is great. I use it to test my vision all the time when I am at home/away from my doctor. It is also a fun little tool to test your friends' vision.

    It's useful, but probably NOT the BEST eye test out there.
