A premium iOS app that teaches English and Spanish with an AI voice coach named Lumi. Speak, listen, read and write — with instant, native-level feedback.
English and Spanish. Each is an independent track from CEFR A2 to C1, with its own coach, decks and progress.
US$9.99 per month, per language, billed through your Apple ID. A 7-day free trial is included when you start a subscription.
Yes. English and Spanish are independent subscriptions — you can hold both at the same time and switch tracks any time inside the app.
English is our deepest track: it includes the Voice Coach with Lumi plus 6 distinct AI characters, the Pronunciation Lab, Roleplays, the Writing Coach and Word of the Day. Spanish ships with the full shared toolkit — Voice Coach with Lumi, Guava Stories, Grammar Clinic, Listening Lab, Conjugation Sprint, Flashcards and Memory Palace — and grows every month.
Open Settings on your iPhone → tap your name → Subscriptions → GuavaSpeak → Cancel Subscription. You keep access until the end of the current billing period.
Lumi listens to what you say, gives you native-level feedback on pronunciation, grammar and word choice, and answers back in a natural voice. In English you can also switch to one of 6 character voices — recruiter, barista, traveler, editor, fitness coach, student.
GuavaSpeak is designed for A2 to C1 learners. If you already know the very basics, you'll be at home from day one.
Core lesson and review content is designed to work offline. Voice coaching and AI features need an internet connection to reach the model.
The interface is translated into 10 languages so you can learn English or Spanish from your own native language.
We collect the minimum needed to run the app: your account email, your progress, and purchase state via Apple. Audio is processed transiently to give you pronunciation feedback and is never sold. We don't run ad SDKs or cross-app tracking.
You can delete your account directly from within the GuavaSpeak app. Deletion is permanent and removes your progress.
