After each review, your rating — Again / Hard / Good / Easy — helps estimate memory strength and calculate the next review date. Words you remember well appear later; words you may forget return sooner. Every card stays connected to its original sentence. Context Cloze, spelling, and listening exercises all use the context and original audio where possible. Remember it where you first encountered it. 【SYNC】 Study history, saved items, and podcast subscriptions sync between iPhone and iPad through iCloud. 【MEMBERSHIP】 Yujingdao is free to download and use.
