[Achieve "Conversational English" in the Shortest Time with Instant English Composition]
For adults who want to relearn English.
This app focuses on instant English composition, which trains you to "translate thoughts into English," and on English vocabulary actually used in everyday life, rather than TOEIC preparation or test-taking. With approximately 14,000 example sentences using AI audio and automatic review based on the forgetting curve, you can effortlessly acquire conversational English.
■ Three Features of the App
