Language Cipher

Language learning that works on a plane, underground, anywhere. Cipher runs a full AI language tutor entirely on your iPhone. You speak, an AI avatar answers in character, grades what you said, and adapts. No internet. No account. Nothing you say ever leaves your device. SPEAK, DON'T TAP Cipher is built around conversation, not flashcards. Every mission drops you into a real situation - checking into a hotel, arguing about a taxi fare, explaining symptoms to a doctor -with a character who responds to what you actually say. Missions are generated fresh by the on-device model, so no two runs are the same. IT ADAPTS TO YOU The Adaptive Flow Governor targets roughly an 85% success rate. Answer well and the difficulty climbs. Struggle with a pattern three times and the Refinery isolates it and drills it until you own it. TRAVEL CHEAT SHEET Thirty-two hand-picked phrases for the situations you hit on day one: greetings, essential questions, eating out, directions, emergencies. Tap any phrase to hear it. Drill the whole sheet or one set. No AI needed, so it is instant and works offline from the moment you install. SIX LANGUAGES, THIRTY PAIRS Japanese, Mandarin, Spanish, French, Italian and English, each one available to learn AND to learn from. An Italian speaker can learn Japanese, and the whole app speaks Italian back. TRULY PRIVATE The AI model ships inside the app. There is no server, no account, no analytics, and no subscription. Your voice, your progress, and your mistakes stay on your iPhone. AI model is included. Download once over Wi-Fi and Cipher never needs a connection again.
