I am from Recife in Brazil South America, and I dont want to do this,I dont do reviews, but this dictionary is so wonderful, i felt like it needed one... So basically, I would like to say that,this is the best dictionary in the world for Brazilians that are trying to learn English.Mainly because when it describes a word? It describes it in context for the word, in a phrase or something... So,you already know from the definition how to use it, and the purpose that the word in the English language and grammar has in the phrase. Its simply the best.The only problem is that its its very limited in the the number of words it has, it has only a few, not a lot of words... I wish it had as many as its textbook has, and you could buy that app with that many words in it.
