About

Mäx

Features
Read full description

Mäx teaches the parts of a language that word lists never fix: which article a noun takes, which case or preposition it wants, where the verb goes, and when one past tense beats another. Everything happens in whole sentences. You pick the missing word, and the app tells you why it was that one — not just that you got it wrong. FOUR COURSES, A1 TO C1 German — der, die, das, Dativ and Akkusativ, Perfekt and Präteritum. Spanish — ser and estar, indefinido against imperfecto, the subjunctive. French — le and la, passé composé against imparfait, the subjonctif. English — American English, following the British Council–EAQUALS Core Inventory and the Oxford 3000. Read the explanations in English, Spanish, Portuguese, French or German, and choose how much translation you want: always, only after you answer, or never, for full immersion. No course is ever explained in its own language. Switch course in Settings; each one keeps its own progress. WHAT'S IN EACH COURSE • More than 1,100 nouns, each with its article, plural and topic • Around 600 verbs with their key tenses, and about 270 adjectives • 40 grammar rules from A1 to C1 (45 in French), each with a table, worked examples and its own drill • 150 read-along stories, 30 per level, highlighted as natural voices read them • 15 reading passages where any word can be tapped for its meaning • 50 listening and 50 speaking exercises; the speaking drill checks what you actually said WAYS TO PRACTISE Daily mix · Articles · Cases and prepositions · Verb forms · Grammar in a sentence · Flashcards · Hangman · Listening · Speaking · Spaced review The review queue brings a word back just before you would forget it, and drops it once it sticks. Build your own flashcard decks by topic, word type and level, or describe the deck you want to Mäx AI. Progress shows your streak, the week at a glance and six months of practice. MÄX AI Stuck on a rule? Ask Mäx AI, the built-in tutor, about the exact question you just missed. It answers only about the language you are learning. PRIVACY No account, no sign-up, no ads, no analytics, no tracking, no subscription. Every exercise works offline. Only two things use the internet. Mäx AI sends what you type, along with the two languages and your level, to our server and on to DeepSeek to write the answer. The app asks you before the first time, and saying no leaves everything else working. The natural voices also download in the background, and until they arrive the device voice reads instead. Your progress stays on your phone and is deleted with the app. The microphone is used only in the speaking drill, and only to check what you said. Declining leaves the rest of the app working normally.
