Learn words you'll actually remember. Vunzo schedules every flashcard for the moment you're about to forget it. That's spaced repetition: words you know come back rarely, words you don't come back soon — so your time goes where it's needed. WHAT YOU GET • Your own library of words and phrases, organised in categories • Review by typing or speaking the answer, graded automatically • Listening practice: the card is spoken, not shown • Conversation with an AI partner at your level, by typing or by voice • Practice exams for language certificates, with AI marking of writing and speaking • Full verb conjugation: every tense and mood, reflexive forms, and the prepositions each verb takes • AI help when adding a word: translations, synonyms, grammatical gender and a natural example sentence • Review reminders, scheduled on your device • 17 learning languages, 20 interface languages VERBS, DONE PROPERLY Most vocabulary apps stop at the infinitive. Vunzo conjugates across every tense and mood, attaches the reflexive clitic the way each language actually does it, and shows which preposition a verb takes — the detail that separates understanding a language from memorising it.
