It’s remote-controlled, pleasant for patients and providers, and FREE. Similar chart projector functionality usually costs over $1000. Check out the last screenshot to see more information on the clinical reviews in peer-reviewed publications and their conclusions. Useful for: - Triaging - House visits - Patients who have memorized the office chart Features: - Randomizable Snellen Chart - Randomizable Tumbling E Chart - Randomize the whole chart or one line at a time - Smooth interface with animations - Basic remote - Metric / Feet functionality Description: Eye Chart Pro is a generator for randomized Snellen and Tumbling E 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. Tap another button to toggle between Snellen and Tumbling E charts. 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 Pro! Though this unique, notebook 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. Eye Chart Pro was made with the best of intentions, and we hope to continue improving it. Your feedback is appreciated! Here is a summary of clinical evaluations we have found: ETDRS Chart on Eye Chart Pro on iPad: “Validation of the visual acuity iPad app Eye Chart Pro compared to the standard Early Treatment Diabetic Retinopathy Study chart in a low-vision population” Journal of Telemedicine and Telecare. Conclusion (summary quote): “The ETDRS chart function on the Eye Chart Pro application can reliably measure VA across a range, from normally sighted patients to those with low vision.” Sloan Chart on Eye Chart Pro on iPad: “The validity of visual acuity assessment using mobile technology devices in the primary care setting.” Australian Family Physician. Conclusion (summary quote): “The high level of agreement of visual acuity results between the Snellen wall chart and both mobile technology devices suggests that clinicians can use this technology with confidence in the primary care setting.” Tumbling E Chart on Eye Chart Pro on iPad: “A Pilot Trial of the Ipad Tablet Computer as a Portable Device for Visual Acuity Testing” Journal of Telemedicine and Telecare. Conclusion (summary quote): “Bland-Altman analysis revealed a mean difference (bias) of 0.02 logMAR units between the VA results from the iPad chart and the light-box chart, with 95% limits of agreement of -0.14 to 0.19.” We are not responsible for the above studies, so please check out the papers above if you have further questions. ## Key features - Randomizable Snellen Chart - Randomizable Tumbling E Chart - Randomize entire chart or line by line - Smooth interface with animations - Basic remote control - Metric / Feet functionality ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | ETDRS Chart 1 | $39.99 | one-time | | Professional Version with ALL Features | $39.99 | one-time | | Premium Home Edition of Eye Chart Pro | $19.99 | one-time | | Advanced Remote Control | $39.99 | one-time | | All Charts | $39.99 | one-time | | Professional Package | $199.99 | one-time | | Value Pack | $59.99 | one-time | | Amsler Grid in Portrait and Landscape. | $9.99 | one-time | | HOTV Chart | $19.99 | one-time | | Sloan Letters Chart | $19.99 | one-time | | Sloan Duochrome Chart | $39.99 | one-time | ## Recent user reviews (10 of 66) All indexed reviews: https://appshunter.io/ios/app/eye-chart-pro/id364802332/reviews.md ### 3/5 — Bug *2025-07-25, version 3.1.0* There is a bug. If you tap the Settings cog, then [About / Show directions], the overlay cannot be dismissed. Also, not sure how to change between Home/Medical user, if the wrong one was selected at install. Unclear if there’s any difference in functionality. ### 5/5 — Excellent support *2025-02-02, version 3.1.0* I had no connection between the devices for a couple of weeks, I sent an email, the support team answered me, updated the app and it’s working again. Thank you so much for your support! ### 1/5 — Mala actualización *2024-11-23, version 3.0* Se actualizo la app después de mucho tiempo y dejo de funcionar en mi iPad que usaba, ya compré una 9 y funciona pero el control ya no conecta en la app, yo pague la versión PRO espero que solucionen el problema ### 2/5 — What size iPad is this for? *2022-10-08, version 2.0.4* I loaded it on a small iPad and a larger iPad Pro. The chart fills the screen on each which, obviously cannot be correct since they both say to use it at 8’. Either it must adjust the letters to the size of the screen or adjust the recommended viewing distance to compensate for the size of the letters. Looks like they are about the right size on the smaller iPad Air and much too larger (Warranting a viewing distance of perhaps 11 or 12 feet rather than 8) on the large iPad pro. If the app runs on multiple form factor devices it needs to compensate or at least alert users of an issue. Barring that issue, the free version does everything I would expect, but that issue is significant. ### 2/5 — Paid app *2022-05-09, version 2.0.4* No preview of functionality ### 1/5 — Worked great at onetime *2021-08-07, version 2.0.4* Worked great for the first few years after purchase, but now it does not work at all. Just keeps taking me to a page asking me to make purchase of the app again, not happening! ### 5/5 — Fantastic app *2021-07-11, version 2.0.4* I just bought this app in June 2021 and it works fantastic. I use this app everyday to both check my vision and practice Active Focus. The remote control feature from my iPhone is awsome, I love that I can sit on the couch and isolate any line on the Snellen and practice clearing up print and exercising my focusing ability. Great job in making this app, I also loved that you could try it out before purchasing. Once I tried it out I immediately purchased this app and it was well worth the money for me. Keep up the great work. ### 2/5 — Was great... not after latest iOS update. *2021-03-10, version 2.0.4* Worked for years and was wonderful. After last iOS update, no w crashes immediately upon launch. Would be 5 stars otherwise. ### 1/5 — Doesn’t work with iOS 14 *2020-12-21, version 2.0.4* App hasn’t been updated in 4 years. Immediately crashes on app launch and apparently is incompatible with current iOS version. Time to look for a new eye chart app.. 😕 ### 1/5 — Was great,now doesn’t work. *2019-11-23, version 2.0.4* Updated to latest IOS for iPad and this app now doesn’t work. Did love to check my and my boys vision using this app, but if isn’t fixed will have to find a different app. And the support website is not a “trusted” website. So not comfortable sending the developer this issue. ## Frequently asked questions about Eye Chart Pro ### What does Eye Chart Pro do?
