Not voiceover friendly voice

I found this app on AppleVis. Thought it sounded great because of the conversion component. I then found that component would cost a $1.99.
They still thought it would be worth it and purchase it. Now trying to use the app with voiceover is very frustrating and not operating at all. Very, very disappointed. I did not want to give it any stars but I have to give it at least one so that I can send this review
