Dynamic Reader helps you read faster, much faster. It uses a technique called “Rapid serial visual presentation” (RSVP) in which words in a book are displayed one or a few at a time in a fixed position:

“The unique method used by RSVP allows for the reading of unlimited text in a limited position. Researchers from Carnegie Mellon have found that as many as 12 words per second are readable in controlled situations (720wpm). Further research has shown that for shorter pieces of text, RSVP formats increased reading speed by 33% with no significant differences in comprehension or task load.”
