How this works
869 pages turned into questions, each shown back just before you would have forgotten it.
- Review — a prompt, your answer, then four buttons. Each one sets when you see the card again.
- Drill — a printed table with one column hidden. Same schedule. Start one from a chapter below.
- Progress — this screen. What is sticking, chapter by chapter.
Nothing to set up. Press Review.
