Eye Chart Pro is a clinically-reviewed, randomizable visual acuity exam. 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.”

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!

I am a neurologist and use EyeChart Professional on my iPad quite frequently seeing patients on rounds and in the clinic. This newest version of Eyechart has several features including the ability to test acuity at a variety of distances from the patient. I can hold it 10 feet from the patient inside the clinic and easily switch to 4 feet when I’m at the foot of an inpatient bed. You can also isolate rows for testing acuity, not to mention limitless randomization, which is particularly useful as patients can subconsciously familiarize the fixed letters on hand cards or wall charts, throwing off the accuracy of repeat testing. Though I mainly use the Snellen chart for acuity and the Amsler grid for visual field defects, there are numerous advanced charts for optometrists and ophthalmologists. It would not surprise me to see an iPad with this application on the wall of eye doctors’ offices, as this app has countless more features and versatility than the anachronistic wall projector, and the long term cost would be less (e.g. several hundred dollars to replace a projector bulb). I strongly recommend this app for any physician who does visual screening, and certainly for eye specialists. It is simple enough for non-medical individuals to use to test their own vision as well.
Bug
Hlother
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.
Fantastic app

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.
Remote control functionality has been updated for newer devices.
