Now in Haitian Creole The entire app — including every N-400 interview question — is now available in Haitian Creole, alongside English and Spanish. Also in this update: • Simpler setup. Picking your language and exam type takes fewer taps, and you can finish signing up without a ZIP code. • Fairer civics scoring. Fill-in-the-blank exercises now check your answer properly instead of accepting anything you type. • Hall of Fame. Last month's champion now appears at the top of the Compete leaderboard. • Reminders you can count on. Your daily study reminder arrives when it should, and streak warnings work again. • Faster profile photos, lower memory use, and several crash fixes. Thanks for studying with Lexi. Good luck on your interview!
