Read Demon is an application that helps teach you how to speed read, and actually retain the information. Customize the interface so that you’re reading white text on a black background(or black text with a white background), along with font size.
Not only can you control the font color and size, but you can also control the speed that the words scroll past the screen.
It’s hard to believe that you could actually read at 350 WPM, but after 2 minutes with this application I was surprised that I could read that fast(when forced to). It’s much different seeing one word at a time(instead of all of the words on the page). . .but after some practice Read Demon makes it easier and easier.
It comes with 18 different ‘lessons’ right now, but hopefully they will be adding more in future updates(I couldn’t find anything that confirmed this though).
