Language consists of skills such as writing, grammar, pronunciation, listening, speaking practice, vocabulary, and reading - a total of 7 skills you need to master any language. These skills are interconnected, and by developing one, we indirectly develop all the others. But if we develop all skills simultaneously, resonance occurs, and the efficiency of language learning multiplies. This is the task before us: our goal is to turn DoubleReading into an interactive environment where the user can learn a language in resonance, improving all the necessary skills in one place.
