Device(s) App Was Tested On:
As of today, May 3, 2016, both Calculator HD Pro Free and their Calculator Pro Free apps are fully accessible with VoiceOver. I wrote them on april 19, 2016 and they released updates to both apps today. For $2.99 you can remove ads.
If you need a good calculator with a history tape or just need a good scientific calculator, I recommend checking these out. Great app support!
