Der, die or das? Stop guessing. DerDieDas turns the hardest part of German — noun gender — into a two-minute daily habit. Answer, see the word inside a real sentence, and watch your accuracy climb. WHY IT WORKS • Short rounds. Ten words, about two minutes. It fits in the gap before your coffee is ready, which is why people actually come back to it. • Every word in context. Each answer is followed by an example sentence with a translation, so the article attaches to a picture instead of a rule you have to recite. • It follows your mistakes. Words you get wrong come back sooner. Words you have mastered step out of the way. WHAT'S INSIDE • 3,000 of the most common German nouns, graded A1 to C2 • Nine ways to practise, from articles to plurals, spelling, word order, adjective endings and meaning: • Article Trainer — a round of words with instant feedback and a score at the end • Streak Survival — three lives, one wrong answer costs one. How far do you get? • Plural Trainer — one or many? Pick the plural from four endings it could have taken • Sentence Builder — put a scrambled sentence back in order, at your own level • Word Speller — build the word letter by letter and pick its article • Dialogue — build a question, then the reply that follows it • Vocabulary — German to meaning, and meaning back to German • Adjective Endings — roter, rote, rotes? Pick the ending the sentence needs • Mixed Round — a bit of everything, and you pick what goes in • Word library — search by spelling or meaning, filter every word, see your accuracy on each • Statistics — accuracy over time, a der/die/das breakdown, and where your streak usually breaks • Achievements and daily streaks, with a reminder at a time you pick • Apple Watch app — practise from your wrist, in sync with your iPhone • Interface in English, German and Russian; light and dark NO ADS, NO SUBSCRIPTION No advertising. No subscription. No paywall in the middle of a round. No sign-up needed: your progress lives on your device, and if you ever want it on a second device, sign in with Apple or Google and it follows you. Whether you are working towards A1, sitting a Goethe exam, or have lived in Germany for years and still hesitate before every noun — this is the drill that fixes it.
