Learn German, one beat at a time. Klartakt is a calm, serious German course built around one idea: it is not enough to see a word. You have to meet it again, at the right moment, until it is yours. SPACED REPETITION THAT ACTUALLY WORKS Every card comes back just before you would have forgotten it. Words you find hard come back sooner; words you know get out of your way. Over 9,200 reviewed cards, A1 to C2. DER, DIE, DAS — SOLVED German genders are taught in colour, so they stick to the word instead of floating next to it. Plus noun plurals, verb forms and Perfekt. TALK, WITHOUT THE FEAR Gespräch is your AI conversation partner. Pick a situation — at the doctor, at the Amt, small talk with a neighbour — then type or hold to speak. It replies in German and shows you a corrected version of what you said, with the grammar lesson behind each fix. GRAMMAR IN SHORT BEATS 132 Grammatik-Takte: one idea at a time, with worked examples first and drills after. No wall of rules. IN YOUR LANGUAGE, FROM DAY ONE The whole app speaks 11 languages, including full right-to-left for Arabic and Persian. Beginners are never stranded in a German-only interface. LEARN TOGETHER Join a classroom, get homework from your teacher, and see how the class is doing. Add friends and compare progress. Most language apps leave you alone with a streak; this one does not. BUILT FOR THE EXAM Goethe and DTZ vocabulary tracks with a deadline-aware daily plan, so you know whether today's pace still gets you there. ALSO INSIDE • Listen mode — hands-free audio review for commutes and chores • Zahlen-Studio — numbers, prices, dates and clock times • Sprints — 60-second drills for genders, plurals and Perfekt • A dictionary with full verb conjugations • Import your own words from a photo, a link, or by typing FREE AND PRO Klartakt is free to use: 10 new words a day, and reviews are never capped. Klartakt Pro removes the daily limit and unlocks Gespräch, Listen mode, the Grammatik-Takte and the phrasebook. Weekly, monthly and annual plans are available, and the annual plan includes a free trial.
