Increases focus, helpful distraction – Schultz Tables - increase your reading speed! Review
You don't realize it until you've played with it a few times, but this app helps keep you focused and maintaining accuracy. The effect seems to last quite a while, although I keep playing with it so I'm not sure if it's repetition or learning that does it. Worth the effort.
