Translate text, voice, and photos 100% offline and private. No internet, no limits, no sign-up. Your words never leave your phone. OffLingua is a powerful, privacy-first offline translation app that runs entirely on your iPhone, redesigned from the ground up to feel like a brand-new product while keeping its core promise intact: no internet, no uploads, no tracking. Powered by TranslateGemma 4B, Google DeepMind’s advanced open translation model running fully on-device, OffLingua delivers high-quality AI translation across 55 languages including English, Spanish, French, German, Chinese, Japanese, Arabic, and more, even in airplane mode or remote areas. The app supports multiple input methods in a refined, premium interface: instant text translation, photo translation with automatic OCR and improved overlay readability, and natural voice translation using on-device speech recognition. A clear three-mode navigation (Text, Speech, Photo) sits at the core of a new visual identity with modern typography, spacing, accent colors, intentional motion, and translation cards that offer clearer hierarchy, micro-feedback, inline “listen” actions, and smarter error states. New features elevate the experience further, including a Quick Translate Panel for one-tap translation, language swapping, live transcripts, speak and listen modes, and smooth translation streaming. Conversation history is stored locally in an encrypted database, allowing you to switch languages mid-conversation and resume any session from the sidebar. Transparent on-device performance indicators clearly show when the app is offline-ready or when the model is downloading, without exposing technical clutter. All translations happen 100% on your device. No cloud servers. No data collection. No tracking. Your text, voice, and photos never leave your iPhone, fully compliant with GDPR and global privacy standards. Download the AI model once on WiFi, then use OffLingua offline forever. Break language barriers without breaking your privacy.
