Although apparently the two formulations suggest the same, differences are important and need to be clarified. In clarifying this difference we will start from the definition of speed reading. Speed reading is a human ability that can be transformed into a useful skill through training.
In other words, ability designates a potential that is not yet being used. When this potential begins to be properly stimulated, through training, it turns into usable skill. This skill is fast reading and it brings us a lot of benefits such: earning time, better understanding of information and its more efficient memorization, effective learning, better reading motivation.
And now let's see more clearly what's the difference between a program for learning speed reading and a speed reading app.
