About this app

🎉 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 iPhone, 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 👎 on the bubble — it gets better.

What’s new

• Renamed to 'Đôi (Doi) — Couple Interpreter' so you can find the app by typing 'doi' — no Vietnamese keyboard needed.
• More natural translations: Korean intensifier slang is no longer translated literally, and misheard words from speech recognition are corrected from context.
• Fewer translation failures: requests that were rejected in some regions are now routed around the problem.
• Everything is still free during the launch period.
