Ratings and reviews

why there is no "Play/Stop" button? do I really need to get back to the beginning every time I want to stop for a second? is difficult to tap in the right place, in the right moment, most of the time you will get the translation of the word trapped. not comfortable

I found the selection of books very good - plenty of Russian classics. Reading and sound quality excellent. There are plenty of options on the menu to adjust voice, reading etc. However, the app lacks a possibility of bookmarks, which makes finding the place where you leave off reading difficult. There is also no possibility to search within the text.

not much options for languages you want to learn
