DLL Ebook - the interactive coursebooks app for learning languages. It is based on the direct method of language learning.

The application is an ideal tool for learning languages, not only because it contains a huge amount of material (over 700 vocabulary items and explanations, including many examples of how to use each word in different situations), but also because it is very easy to use. All you need to do is to tap the word, and you will hear the correct pronunciation. If you don't know the pronunciation, you will be able to check it by checking the translation.

Apart from that, you can check the translation of the entire sentence and the translation of the whole chapter.
