Small mendment to a free iOS app which helps children who have difficulty readng (dyslexia)

If a child who has reading difficulties sees any word on an iPhone or iPad screen they can just touch the word and that word will be immediately read aloud helping the child to carry on reading without interruption and helping them understand the text. The app currently works with any previously uploaded files on the iPad or iPhone and also with Google web files. However, I need the app to read words aloud from Kindle books. A fuller explanation is given in the attached WORD file.
