Unless it improved in the last six or eight months, Pureflix has some serious accessibility issues. I dropped it because it once was accessible on both my iPhone and iPad as well as my Apple TV. It was also accessible on my PC. When I cancelled the service it was no longer accessible on any of my devices other than the PC and that was only marginal and not very good.
I spoke to several people at Pureflix and they were aware of the issue and encouraged several blind individuals including myself to get a refund for our service rather than work toward accessibility.
I hope they changed or will change soon. They had some good family friendly content on there.
