DuoLingo is one of the most dependable apps when it comes to learning a language the authentic way. Most courses here are created and offered by native speakers, this ensures accuracy regarding how the language is spoken today. Another feature that makes DuoLingo reign supreme is that it is not aimed solely at an English native speaker. For each of nearly 100 language courses, there is the option to select a course designed for those with a first language other than English.
