Hello, my company Philosoft Mobile develops apps for the blind and visually impaired, but in addition to this we sometimes do auditing for other company's apps in terms of accessibility.
I my self am a blind person, and so, I have no problem checking behaviors with screen readers like Voiceover and Talkback, However, I need to pass all visual issues, like font size, contrast etc. to my sited colleagues.
I ren into an article that introduced me to a verry nice software that runs on my PC or Mac depending on the software I am checking – Flow Analyzer for Mobile .
The app Flow Analyzer for Mobile, is fully accessible for me as a blind user. While it is not a replacement to human testing, and does have some more testing to include, it will give me a nice report on visual and nonvisual incompliances with WCAG 2.0.
The report is verry detailed and include reference to articles about any issue it reports as a problem.
I find that the app gives me a verry good starting point on my audit.
One mor thing, as a blind user I find myself trying to explain accessibility problems to the developers of an app I use, even outside my role in my company, now I can direct the developers to this app, and it explains most of the accessibility problem's.
Hope this will help someone.
