For couples who don't share a first language. Fluent Duo is built around one simple loop: you record a 30-second voice note in your partner's language. They listen, react, and send back a 15-second correction. That's the whole app. Tomorrow you do it again - even when you're not in the same room. HOW IT WORKS - Pair with your partner using a single invite code. No social feed, no strangers. - Every morning you both see the same prompt - small, personal, easy to answer in 30 seconds. - Record your voice note. Hear theirs. - React with one tap: loved it, cute-wrong, or "try again." - Optional: send back a 15-second correction so they can hear how it should sound. WHY COUPLES STICK WITH IT - You're learning the language they actually speak - their parents' dialect, their nicknames, the joke from their childhood. Not what's in a textbook. - Voice forces pronunciation. Text apps let you cheat. - Your partner is the most motivated teacher you'll ever have. They want to understand you. - 30 seconds is too short to skip, so you don't. - The streak is shared between the two of you, not against an app. BUILT FOR - Long-distance couples across time zones - Expats whose in-laws don't speak English - Mixed-language households at home - Anyone who tried Duolingo and quit at lesson 14 WHAT'S NOT INSIDE No leaderboards. No streaks shaming you in red. No chat with strangers. Just the two of you, getting closer in two languages. Available in English, Italian, French, Spanish, Portuguese, Japanese, Korean, Arabic and Hindi. Start with one voice note today. See where you both are in a month.
