U-Dictionary
This app provides three different explainers: "Basic", "Advanced", and "Mastery". Beginners can look up translations of a word in their mother tongue, while more advanced speakers can learn different ways to speak English like a native. The app also has a f a s t and accurate w o r d scanner (文字扫描仪). Scan a word with your phone's camera and the definition will pop up. The app also contains word quizzes (小测验), and listening and writing exercises to help you master English.
Dictionary
The app has plenty of functions, including a dictionary, a thesaurus (类意词典) a "Learners" function, and an "Origins" page. The "Learners" function is very useful for students of the language, as it provides information on how the meaning of a word can change in different contexts, or with other words. The app also provides word quizzes, articles about how language is used, word trends, and a "Word of the Day" section on the app's homepage.
Oxford English Dictionary
The best feature of this app is that it allows you to look up definitions of words even as you're reading things in other apps on your device. The benefit of this app over others is that you can sort your saved words into folders or categories. Unfortunately, one of the major downsides (缺点) is that there is no thesaurus or offline dictionary.
Merriam-Webster
Unlike other apps,that require you to download a bunch of packages before you can access them offline, this dictionary works with or without data on your device. There is also an option to toggle (切换) between dictionary and thesaurus mode. Sadly, because this app has so much to offer, the drawback is a few advertisements, which pop up occasionally.
