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. DEEPLY INTEGRATED WITH iOS - Share Extension — translate any selected text from Safari, Notes, Messages - Siri Shortcuts — "Hey Siri, translate clipboard" via App Intents - TipKit onboarding — discover features naturally - Default screen — choose which feature opens when you launch the app - Dark Mode, Dynamic Type, VoiceOver — first-class accessibility PRIVACY YOU CAN READ - Zero network calls (except Apple's own language pack download) - Zero third-party SDKs / analytics / ads - No account, no login, no email required - All vocabulary and history stay in your device's SwiftData store REQUIREMENTS - iOS 18 or iPadOS 18 and later - First-time use downloads Apple's Chinese & English language packs
