Great way to learn and refine definitions of difficult words
For a good (albeit long-winded) sample of how the app can improve your vocabulary, pronunciation, and usage of English, check out word 30 of Level 2: “verbose.” The narrator delves into a verbose description of the key word and many similar words, eventually defending the title of the app itself.
The pace is quick enough that you can listen to each twice (look in the settings to make this adjustment) and the narrator often tells humorous explanations enabling an understanding of the key words. Perfect for the logofile in each of us!
