About

Deutschly

Features
Read full description

Deutschly is a free, fully offline German learning app — no login, no account, no payment, no ads, no internet required. Everything lives on your device. SMART DICTIONARY 10.000+ words across A1, A2, B1, B2 and C1 levels, straight from real Goethe-Institut vocabulary lists. Search works both directions (German ↔ English) and understands inflected forms — type "gemacht," "fährt," or "Häuser" and land on the right word with an explanation of exactly which form you typed. SPACED-REPETITION FLASHCARDS Save any word from the dictionary and review it with a proven spaced-repetition algorithm. Cards you know well show up less; cards you're shaky on come back sooner. Mark words "Learned" once you've truly got them, and they'll stop appearing in review — unmark anytime from Settings. GRAMMAR THAT ACTUALLY EXPLAINS Clear explainers for cases (Akkusativ, Dativ), articles, pronouns, verb conjugation, word order, and more — with declension tables you can view fullscreen for a closer look. Every topic ends with practice questions (multiple choice, fill-in-the-blank, sentence ordering) that adapt to what you keep getting wrong. DAILY REMINDERS Optional vocab-reminder notifications — pick your days, time window, and interval, and Deutschly nudges you with a saved word and example sentence so a little German fits into your day without opening the app. STREAKS & PROGRESS Track your daily streak, review accuracy per grammar topic, and overall activity — enough to stay motivated, nothing that turns learning into a chore. LISTEN TO WORDS AND EXAMPLES You can listen to every word and example sentence, fully offline, and learn to pronounce them correctly. FUN GAMES & MULTIPLAYER DUELS Play games to learn German in a fun way: Wort-Blitz (beat the clock), Bilderrätsel (name the picture), Der-die-das (guess the article), and Wortpaare (matching pairs) — plus a WLAN duel where up to 30 players on the same network compete live on the same questions, no server or internet needed. Mistakes from games and duels feed straight into your flashcard review, so you actually fix them. LIGHT & DARK MODE A warm, readable "paper & marigold" design that looks good either way. PRIVACY BY DESIGN No account, no cloud sync, no analytics, no ads. Your saved words, review history, and settings stay on your device. Deutschly works the same on a plane, on the subway, or anywhere with zero signal. Whether you're starting from zero or brushing up before a trip, Deutschly gives you a real vocabulary, real grammar explanations, and a review system that adapts to you — all without ever needing to be online.
