this has been the most used App since I bought it a few weeks ago, Well worth the money, with a lot of in app voices to buy if you want or can use default iOS voices if you want, I use this App to read pdf files , it helps me retain the information faster, with a built in dictionary (regex capable) to correct words that are pronounced wrongly, what can I say more ,it has everything you need to read all of your books, documents,articles aloud with the most elegant and customizable way . If only there is a chance this App adds tts voices from Nuance this would be amazing ,from my personal experience Nuance provide great tts engines , also if there is an option to fit pdf by width to read in landscape mode it would be great.
