The app can pick words automatically, or learners can choose the list they want to study today.
Study one word
Open Mini Lesson, listen to the word, read examples, and filter contexts that match the day’s goal.
Mark progress
Mark a word as learned, needing review, or mastered. The word list changes state clearly.
Review before forgetting

Quick guide
Open the Today tab first. The large focus line tells you what to do next. Use Today Words to see the full list, then start the Mini Lesson for the current word.
In Mini Lesson, use the speaker and loop controls for listening. Use context filters to avoid scrolling through examples that are not relevant to your current study goal.
