Very helpful app.
This app is an effective use of time. I use it to read scientific papers for work at the gym and in the car while commuting to work. Few draw backs. The voice doesnt flow well. Tends to pronounce syllables more often than the entire word, which takes some getting used too. And it reads EVERYTHING, which can be frustrating when reading scientific papers. The Pauses are too long at periods, citations and tables.
