Translate with your voice, your camera, and your vocabulary notebook — all without sending a single byte to the internet.
Offline Translator is a privacy-first, on-device translator for 14 languages — Traditional Chinese, English, Japanese, Korean, German, French, Spanish, Thai, Vietnamese, Portuguese, Italian, Indonesian, Dutch and Turkish — built on Apple's native Translation framework. No account. No ads. No tracking. Nothing leaves your phone.
WHY OFFLINE TRANSLATOR
Most translators ship your most sensitive moments — travel notes, medical phrases, contract clauses — straight to a foreign server. Offline Translator doesn't. Every translation happens on-device, powered by Apple's Neural Engine. Turn your phone to airplane mode and it still works.
FIVE WAYS TO TRANSLATE
1. Text. Type or paste. Character counter, save to vocabulary, copy with one tap.
2. Voice. Hold to speak, release to translate. Haptic feedback guides you.
3. Camera. Point your camera at a menu, sign, or textbook page and see translations overlaid live. Tap the shutter to freeze a single frame, or pick an image from your photo library. Vision OCR and translation both run on-device.
4. Hands-free listening. No button to hold: when the other person finishes a sentence, the translation appears in large, readable text. Conversation mode has a hands-free option too. Needs offline speech recognition for the language.
5. Dictionary / Vocabulary. Save any word or phrase with one tap. Revisit your saved list, grouped by date.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
v1.5.0 - Camera translation, upgraded. Plus hands-free interpreting.
[Camera Translation]
- Point the camera at text and see translations overlaid in real time
- Tap the shutter to freeze the frame for a single, easy-to-read translation
- The old Photo Translation is now built in, and you can pick images from your library too
- Garbled text from recognition is now filtered out, so translations stay stable and stop jumping around
[Hands-free Interpreting]
- New Hands-free Listening: no need to hold a button. When the other person finishes a sentence, the translation appears automatically in large, readable text
- Conversation mode also gets a hands-free option that splits sentences automatically on silence
- Hands-free needs offline speech recognition for the language. If it is not available, the app suggests using press-and-hold instead
[Default Translation Mode]
- Choose which feature the app opens straight into
- Set it in Settings, or long-press any feature on the home screen
[Feedback]
- New Send Feedback in Settings. Attach screenshots or videos and send them from your own mail app
[Fixes]
- On the English interface, the home screen Conversation tile was showing Chinese
[Privacy unchanged]
All translation and speech recognition still run 100% on your device. Nothing is uploaded.
