Wow! This is exactly what I was looking for. I compared the letters to a printed Snellen chart, and they are the same size. 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. Also, could you add the Monomer chart letters? Anyway, thanks for this app! Update: actually the feature to make the text bigger with space/enter is even better than audio. I am using a Bluetooth keyboard and use the arrow keys to navigate the different levels. But I didn’t seem to get the letters to appear bigger with space and/or enter 🤔 Tried other combinations too. It’s a Mac keyboard for info.

For someone who has been suffering from low visual acuity all his life, this app still my best way to keep track of my visual acuity through the years. Great Job.

Last version is awful please roll back to previous version or make available previous version. Not useful to me at all. Looking for alternatives

Still can't measure at 6/6 metric unit, even if I changed it, it will always revert to 20/125, kinda frustrating when using it

This app has been excellent for helping with portable VA in tricky areas, until the latest update which has broken it entirely. Attempting to configure it with settings means non-stop crashes.

Use to work fantastically. Now I can't switch to Metric system, user interface became less user-friendly, color choice in menu makes everything unclear when making choices. App worked fine before, now it's a massive pain to use. Going to have to search for another Snellen Chart app.
