A very good app that served its purpose fully. However, there is an exercise which I personally think is pointless and that is the word search in a text block under time pressure. Clear this promotes the "scan" a text, but the test will be based in the context of the words found in the time available, "counted" and because the words are selected randomly each time, it may be that you only always some words towards the end the text is. Even the fastest "Scanner" this lost time.
Basically, however, the best app in this area that I have tested so far
