This is a dictionary for advanced learners. The purpose of using this dictionary will be more like checking the usage of vocabulary, a phrase or an idiomatic expression than looking up the meaning. While looking up a word, it is also a chance for you to check other words in the definition and sample sentence. You may find it inconvenient at first, since there is no cross-reference inside the dictionary and all information is written in Chinese. However, through using Chinese to understand the meaning will let you become more immersed in the language and dig more into pragmatic aspects of Chinese. It is even more useful when looking up something that only exists in Chinese culture.
The definition is complete and the app opens smoothly, no lag due to the big data base of lexicon. Words or phrases in any field are available, so it is not going to disappoint you as a free app. I would also recommend it as a quick tool for a Chinese teacher overseas.
