How They Compare in Detail
Study Approach
Citizen Now uses a traditional study-tool model: flashcards, multiple-choice quizzes, and audio playback. You read or listen to questions and tap the right answer. It covers the civics, reading, and writing components and includes helpful extras like a representative lookup tool and N-400 interview questions.
OathPrep takes a different approach: you sit in a simulated interview with an AI USCIS officer who speaks to you, asks follow-up questions, and behaves like a real officer would. You answer by speaking, not tapping. This means you practice the skill that actually matters on interview day: responding verbally, in English, under light pressure.
Language Support
Citizen Now is an English-only app (content sourced from USCIS). OathPrep shows real-time subtitles in 13 languages, Spanish, Tagalog, Mandarin, Haitian Creole, Vietnamese, Hindi, Korean, Urdu, Bengali, Portuguese, French, Russian, and Arabic, so you always understand what the officer is saying, even while you practice responding in English.
Pricing
Citizen Now is free. That’s its biggest advantage. If budget is your primary concern and you just need to memorize the civics answers, Citizen Now is a solid choice.
OathPrep costs $39.99 for 10 voice interview sessions (~$4 each). Additional sessions are $4.99. There’s no subscription, you buy once and use your sessions. For context, a single session with a private citizenship coach typically costs $70 or more.
Platform & Accessibility
Citizen Now is a native iOS and Android app (1M+ downloads, 4.9-star rating). It also works with CarPlay and Android Auto, which is great for passive listening during commutes.
OathPrep is a web app that works on any device with a browser, phone, tablet, or computer. No app store download required.
Our Recommendation
OathPrep is the tool that actually prepares you for what happens in the interview room. The USCIS officer speaks to you, and you need to respond confidently in English. No flashcard app replicates that. OathPrep does.
Citizen Now is a fine free supplement for early memorization, but don’t mistake knowing the answers for being ready. Most people who fail the interview know the material — they freeze under pressure. OathPrep is how you make sure that doesn’t happen to you.
