## What is Đôi (Doi)?

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. Manage or cancel anytime in your App Store account settings.

## Version history (last 5 releases)

### 0.5.5 — 2026-11-03

• Easier first run: the language pair is pre-selected from your phone language, and you can skip the tour and start right away.
• The day after your first conversation, a single reminder that yesterday's words are still here (you can turn it off in Settings).
• Stability and usage-stats fixes.
• Everything is still free during the launch period.

### 0.5.4 — 2026-10-17

• 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.

### 0.5.3 — 2026-10-08

• A feature tour for first-time users: face-to-face on one phone, side-by-side mode, talk/type/listen, two-phone mode and earbuds, in six pages.
• On-screen tips that explain each button right on the translation screen. Revisit both anytime under More › How to use.
