Đôi — Couple Interpreter

Everything is free right now to celebrate the launch! Đôi means "a pair" in Vietnamese. It's an interpreter for two people who don't share a language — face to face. ■ In a lover's voice Not a translator: it says what you would say if you were a native speaker talking to your partner. Vietnamese uses anh/em, Korean uses intimate speech, and the pet names you set (oppa, em, babe…) go straight into the translation. Pick Southern, Northern or standard Vietnamese. ■ Hold the button and talk Put one phone between you; each of you holds your own language button and speaks. Subtitles first, voice if you want it. Loud place? Use Two-phone mode: your phones connect and you hear your partner in your earbuds. Hands-free when your hands are busy. ■ Language pairs Korean ↔ Vietnamese · Korean ↔ English · English ↔ Vietnamese ■ Also - Conversations stay on your phone. No account, no ads. - Type instead of talking when you need to. - On-device translation takes over when you're offline. Translations are generated in real time by AI (Google Gemini). If a line sounds off, tap the thumbs-down on the bubble — it gets better. ■ Đôi Plus (optional subscription) Everything is free during the launch period. After the paid launch, the free plan gets a daily translation limit; Đôi Plus removes it. One purchase covers your partner's phone too when it's linked with your couple code. - Monthly $2.99 / Yearly $19.99 (prices may vary by region), 7-day free trial - Subscriptions renew automatically for the same period unless cancelled at least 24 hours before the current period ends; payment is charged to your App Store account.
