When we first released Soundproof we had to make the difficult decision to delay polishing our VoiceOver experience for accessibility users.
We had done some work on this already, but due to the nature of our custom UI elements such as the time scrubber and Count-In screen, the work was too much to complete first time around.
In hindsight, I really would like to have done this for the first release. It seems to be common that developers don’t bother with this until later, if at all, but it is extremely useful as it tells you things about your visual UI that you wouldn’t have considered. In short, it is a great test of your visual design.
