Duolingo: Learn languages free

Through this bright and fun app, you can not only teach languages to children, but also restore/improve your own knowledge. The entire learning process takes place in a game format with the same rewards. The app provides training in reading, writing, and speaking, starting from the basics and gradually moving on to more complex tasks. The app also has another feature. In addition to translating ready-made templates, you can practice on real texts uploaded by users, or vice versa, upload the required text and wait for the service's users to translate it, and then, of course, pay for this service. It supports Android Wear.
