ReadingPointer simulates the speed reading technique called Meta Guiding. Meta guiding involves visually guiding your eye using some sort of pointer (finger, pen or this ReadingPointer
app) in order for the eye to move faster along the length of a passage of text.
The point is to decrease distraction and focus on the specific words to increase your reading speed. Try to keep moving your pointer slightly faster than your comfort zone to increase the reading speed.
