A #blind friend does use #Conversations_im (or more correct: #Quicksy) by @daniel on Android. I was surprised by that, because I thought, it were not developed with #accessebility in mind. But it seems to work sufficiently well for them.
I don't know if #Monal by @Monal on iOS works for the #visuallyImpaired, though.
For Windows and MacOS no idea at all. Maybe #Gajim by @gajim? Or a web client such as #ConverseJS by @jcbrand?
