You type a word, and you get a comprehensive definition with etymology and a button to push to get a audio clip of the word spoken. It is intuitive and easy to navigate, and you can link it to other apps. It also gives synonyms and antonyms.
To the user who said that it doesnt do anything: I dont understand. Do you mean other than define the word, give you its origin and say it out loud for you? Okay, you got me. ?
Its a great app.
