About this app
This mHealth application intent is to provide and empower mobile regular users and health professionals with the tool with which they can estimate their or others visual acuity, based on a classical Snellen Chart Test. This App is innovative because it transforms an old style poster test design in a new, modern, intuitive, ubiquitous test. One App with a simple user interface, and an intuitive navigation chart using swipe gestures to navigate from optotype to optotype, and with the capability to adapt the Snellen Chart Test to different screen sizes, screen resolutions and user distances.

Thank you. Outstanding app. Love the way it takes into account the screen size and pixel resolution, in addition to distance from the eyes. All adjustable in settings. You're a genius! The performance is actually much better that the charts in my eye doctor's office. Which is projected onto a screen, then reflected in a mirror. Each step of the way resolution is lost! Your app is so much better. Thank you for helping so many people with this app! God Bless you! Please add plain font option!

Great app, much better than any others, but a few issues: * would appreciate diopters measurements * voice control is not comfortable, especially if English is not your native. Couldn't pronounce "down" correctly even a single time. Perhaps some control over wireless head phones could help? * some instructions would benefit some users Thanks for the app!

Very good; IMHO the best of the available apps for testing visual acuity. Two minor points. I just moved from a 5-year old Nexus %x to a Poco F3 which I configured to run in dark mode. In this mode, Snellen Chart does not display the test text. The other available apps do. Also, the text for the LogMar and Decimal figures in the bottom right and left corners is partly cut off.
