Smooth page-curl animations and orientation lock round it out. HIGHLIGHTS, NOTES & VOCABULARY Highlight passages in six colors and attach notes to any range of words. Save words to a personal vocabulary list, then make them stick with five AI word games: Quiz, Puzzle, Hangman, Word Guess, and Riddle Rush.
