Could you please enable the accessibility features on your IOS app so that users of Voiceover are able to use its features?
For instance, the 'finish' or 'go' button at the end of the initial welcome screen is just labelled as "button", and the grid of icons just below the search the web field are all inaccessible to Voiceover users. Simply cannot move focus to any of those icons, and hence they are not read.
Pretty easy fix I think. Most everything else works fine in the app. Great work and thanks!
