LingoUnion

LingoUnion helps you learn sentences you actually need—one at a time. Choose your language pair from 20 supported languages: Arabic, Dutch, English (United States), French, German, Hindi, Indonesian, Italian, Japanese, Korean, Polish, Portuguese (Portugal), Russian, Simplified Chinese, Spanish, Thai, Traditional Chinese (Taiwan), Turkish, Ukrainian, and Vietnamese. HOW IT WORKS • Enter a short sentence in your source language. • With your consent, LingoUnion uses AI to create a translation and training audio in your chosen target language. • If you decline or withdraw AI consent, supported iPhones can use Apple's on-device translation and an installed enhanced or premium system voice instead. • Listen, speak, and write until the sentence becomes familiar. • Return to focused reviews before adding another new sentence. VOICE CHOICE For AI audio, choose from Alloy, Ash, Ballad, Coral, Echo, Sage, Shimmer, Verse, Marin, or Cedar. Marin is selected by default. On-device fallback uses an installed Apple system voice for the target language. DESIGNED FOR FOCUS • One new sentence per day. • A review-first daily schedule. • Up to 300 Unicode characters per sentence. • Saved sentences and progress stay organized on your iPhone. • Interface languages cover all 20 supported learning languages. PRIVACY AI content is sent through the LingoUnion gateway to OpenAI only after you agree to AI data processing. LingoUnion does not persist sentence text or audio on its gateway. This release uses OpenAI's standard API data-retention controls, not Zero Data Retention. API data is not used to train OpenAI models unless the organization opts in; LingoUnion keeps sharing disabled. OpenAI abuse-monitoring logs may retain content for up to 30 days, with limited legal or safety exceptions. Speaking-practice audio is handled by Apple's speech recognition and is not sent to OpenAI or the LingoUnion gateway. A valid annual subscription is required to learn. Availability of on-device translation, speech recognition, handwriting input, enhanced voices, and other system resources depends on your iPhone, iOS version, and selected language.
