This app is an okay free language lesson app but not super helpful on explaining the subtleties of grammar in a language. I am taking the Korean course and there are several ways to say "Hello" and "Goodbye"but this app won't go in depth on what the differences are. With the recent changes, courses I mastered I have to re-learn as they introduce new words I have never seen before. Also remove the TikTok ad with the awful lound sound effects. You expect me to get tinnitus after a lesson?
