We've gotten a couple of reports of accessibility issues with the iOS app, especially with buttons not being read aloud in VoiceOver mode.
I've filed https://bugzilla.wikimedia.org/show_bug.cgi?id=69120 so we don't forget to research exactly how to fix that up -- there should be accessibility role and label fields we can set on the labels and buttons to let VoiceOver pick them up correctly, so that part should be an easy fix once we get in there.
We may also want to make slight adjustments to content HTML to reduce redundant link titles.
