1. 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.

2. This App is innovative because it transforms an old style poster test design in a new, modern, intuitive, ubiquitous test.

3. 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.

1. Love the way it takes into account the screen size and pixel resolution, in addition to distance from the eyes.

2. Going back on Snellen chart does nothing : expected to close app, going back on settings screen exits app : expected to go back to acuity testing screen.Cool app.

3. Also, could you add the Monoyer chart letters? Anyway, thanks for this app! Update: actually the feature to make the text bigger with space/enter is even better than audio.

4. It’s a Mac keyboard for info.Fabulous. App takes into account screen size & resolution which is shown in settings.

5. The only thing I would love for you to add is an option to test near vision from N5 to N60 then this would truly be the most perfect domiciliary app :)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.

6. Good that it takes into account screen size and makes a definition of distance of eyes to screen.

7. One little feature request: an audio/keyboard command to read (tts) the current letters, to verify what I've read (or thought I've read) with my eyes.

8. 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.

9. But I didn’t seem to get the letters to appear bigger with space and/or enter 🤔 Tried other combinations too.

10. I compared the letters to a printed Snellen chart and they are the same size.

11. User can swipe left or right for new letters, as well as up and down to change x/y reading distance.
