Snellen Chart

João Meneses

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.

Ratings and reviews

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!

Been using this app for 2+ years, kinda panicked and thought that app support was gone a couple of weeks back, glad that it's sorted now. Thank you so much, it helps me a lot in my practice and for my patients! 😊

Great app. I used it for couple if years and it really helps. Nice selection of options. And the Dev was quick to respond and add Missing features. Overall nice and useful.
