• Challenges open on the quiz with "Sam challenged you," so you know what you're playing for, and you can challenge them right back. • Shared results and challenges now include a link to get Quizaroo, so friends without the app can join in. • Your shared result card can show how rare your result is. • Creators can share their published quizzes, and are offered a share right after publishing. • Spectrum results are scaled to each quiz, so strong answers no longer pin you to the end of the bar, and "% aligned" matches what you see. • The streak reminder only comes on evenings you haven't played yet. • Better accessibility: larger text support, Reduce Motion, and VoiceOver now hears whether each trivia answer was right. • Safer community quizzes: a language filter before publishing, and clearer reporting. • Fixes: duplicate quizzes after syncing, challenge links opened during first launch, and ads that didn't show after some quizzes.
