Inside the App
Flashcards that actually teach you something
Every card shows the Vietnamese word, its meaning, a real example sentence with the word highlighted, and cultural usage notes — not just a word and a translation.
Not textbook Northern. Not robotic TTS. Real Southern Vietnamese — the way people actually speak in Ho Chi Minh City.
Free to start. iOS & Apple Watch.
Every card shows the Vietnamese word, its meaning, a real example sentence with the word highlighted, and cultural usage notes — not just a word and a translation.
Built specifically for Ho Chi Minh City — the vocabulary, pronunciation, and slang you hear on the streets.

Over 1,000 sentences, you internalize Vietnamese word order and grammar naturally.
Vietnamese has 6 tones that completely change a word's meaning. Master them all with audio-first quizzes — hear a tone, identify it. Plus 29 consonants and every vowel combination.
96 groups of nearly identical-sounding words — the pairs that confuse every learner. Two-phase quizzes train your ear to hear the difference.
Snap a photo of anything with Vietnamese text and the app creates a custom flashcard set — complete with translations, audio, and usage notes.
Every learner's life is different. Maybe you need restaurant vocabulary for your in-laws' kitchen. Maybe you want to finally understand the karaoke screen. Maybe your boss just sent you a contract in Vietnamese.
Snap a photo and the app does the rest — extracting every word, generating translations with native audio, and building a custom set that syncs to your Apple Watch. Study the exact words that matter to your life in Vietnam.
QuarterSpeak teaches the language locals actually speak — not the textbook version. Each app is built for one city, one dialect, one way of life.
