ON-DEVICE TUTOR NEEDS APPLE INTELLIGENCE. On an Apple Intelligence iPhone (15 Pro+, iOS 26) with Apple Intelligence on, conversation stays on your phone. On a phone that cannot run that model, enjoy 5 free AI conversation turns daily or activate the ultra-affordable Cloud Tutor (US$0.99 per month for 600 AI replies/month). Guided voice dialogues, microphone speaking practice, and written exercises work free on every iPhone. Practice a new language by talking — privately, on your own phone. Language Tutor is a practice tool you use by chatting. A patient tutor role-plays a conversation partner in your target language, replies at your level, and gently corrects mistakes. ON-DEVICE FIRST, PRIVATE BY DESIGN On an Apple Intelligence phone the tutor is Apple's on-device model — no account needed, even in airplane mode. Saved phrases and settings always stay on your phone. LEARN BY DOING, NOT MEMORIZING • Voice input — tap the mic and practice speaking aloud; on-device speech recognition transcribes words privately. • Pronunciation speed & auto-speak — listen at a comfortable, slower pace designed for beginner learners, or have replies read automatically. • Spoken & interactive guided dialogue — tap any line to hear clear native pronunciation or speak into the mic on-device to answer interactively on any iPhone. • Studio ambient music & home widget — practice in a calm studio atmosphere with optional ambient soundscape and a quick-launch Home Screen widget. • Conversation practice — chat through real scenarios: ordering food, the airport, small talk, directions, and more. • Gentle corrections — mistakes are corrected kindly, with a hint when you get stuck, so you actually improve. • Suggestions when stuck — tap starting lines, or ask “What should I say?” mid-chat for short reply ideas. • Instant meaning — tap a tutor message and what it means appears in your own language, right under the bubble. • Choose your level — beginner to advanced; the tutor adjusts how it speaks to you. • Pick your target language — separate from the app's menu language. • One tap to start — your language, level and scenario carry over from last time, so practice begins the moment you open the app. LEARN KOREAN — INCLUDING TOPIK Practice Hangul conversation by exam band (TOPIK 1–6). The tutor coaches particles and honorifics, and written drills follow the same bands. Travel Korean is here too — speaking practice, not flashcards. A REAL STUDY TOOLKIT • Phrasebook — save useful lines from any chat into a local phrasebook, grouped by scenario. • Scenario guides — offline guides for common situations, plus grammar and usage tips. • Review & practice record — review saved phrases and track days practiced locally on your phone. BUILT THE BARO WAY • Works offline — the on-device tutor practices anywhere, even with no signal. • No ads, no tracking, no analytics, ever. • Big text, high-contrast design, single-tap controls. • English, Korean, Japanese, German, French, Arabic, and Simplified Chinese interface. OPTIONAL CLOUD TUTOR — AUTO-RENEWING SUBSCRIPTION For phones without Apple Intelligence (or learners who want fast cloud AI replies), Cloud Tutor provides a generous allowance of 600 AI replies per month (~20 per day). Guided dialogues, on-device microphone practice, and written exercises stay free on every iPhone without a subscription. No ads. Cloud Tutor — US$0.99 per month (600 AI replies per month). Renews automatically until you cancel; manage or cancel in Apple Account settings. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://lionandthelab.github.io/omit-talk/privacy.html HONEST ABOUT WHAT IT IS Language Tutor is a practice and study tool for everyday conversation, not a certified course or a human teacher. Where the on-device tutor cannot run, the app says so — there is no silent stand-in. Part of the Baro family — The tools you reach for first.
