Fluent English Pro has no ads and more books than the free version. It will help you practice understanding native English speakers and increase your vocabulary. It works like an audio book reader and also provides translation for words that you don’t understand. For better learning, it also provides pronunciations of each word in several different voices. To learn efficiently and to be able to use the dictionaries, your native language needs to be one of the following: Arabic, Armenian, Bulgarian, Chinese, Czech, French, German, Hindi, Croatian, Hungarian, Italian, Japanese, Korean, Persian, Polish, Portuguese, Russian, Spanish, Swedish, Thai, Turkish, Ukrainian, or Vietnamese. Note that some of the dictionaries and books are very large, so make sure you are on WiFi before downloading them.We reserve the right to anonymously track and report a user’s activity inside of our app, and technical parameters of the phone to help us fix the bugs.
