Fluency Simulator
Speak a new language, for work
Free
Practice real, spoken conversations for your job — against a private, on-device AI. No accounts, no cloud.
Fluency Simulator turns language practice into realistic, spoken role-play. Pick your profession, choose a language, and hold a real conversation with an on-device AI that plays the other party — a patient, a client, a customer — while an animated avatar speaks back to you.
Built for professionals whose careers depend on a second language: nurses, doctors, lawyers, real-estate agents, salespeople, managers, and more.
WHAT YOU GET
• 40+ professions across Healthcare, Legal, Business & Sales, Architecture & Engineering, Management, Science, Marketing, and Hospitality
• Practice any language pair, from CEFR A1 (beginner) to C2 (proficient)
• Speak aloud and hear a natural, high-quality on-device voice reply
• An animated avatar that reacts as it talks
• A feedback report after every session: accuracy, vocabulary, role-fit, and a concrete next goal
• Your history and progress, tracked over time
SUBSCRIPTION
Fluency Simulator is free to download. Access to unlimited role-play sessions and the other Fluency Basic features listed above requires a separate auto-renewable monthly subscription. Pricing is shown in the app before purchase. You can manage or cancel at any time in Apple Account settings.
100% PRIVATE — WORKS FULLY OFFLINE
• The conversation, speech recognition, and speech all run on your device
• No account, no sign-up, no cloud, no analytics
• Nothing you say or type ever leaves your device
Requires an Apple Intelligence–capable device. The microphone and speech recognition are used only to hear your spoken replies; audio is processed on device and never stored.
