Mit Spaß lernen! Kommasetzung für Grundschüler - einfach und spielerisch lernen! Wissenschaftliche Analysen zeigen, dass Kommafehler die häufigsten Interpunktionsfehler sind. Die Regeln zur Kommasetzung sind aber sehr abstrakt und teilweise nur schwer zu verstehen - hier setzt die App an! Antatt nur Regeln zu pauken, wird das Sprachgefühl verbessert. Die Regeln werden anhand von vielen Beispielen nach dem Prinzip des Lernkastens geübt. Ein komplexer Algorithmus bestimmt welche Übungen in welcher Reihenfolge und wie vorgelegt werden - so ist schnelles und nachhaltiges lernen möglich. Keine umständliche Bedienung. Klar und einfach, fokussiert auf den Lernerfolg! Um ein Komma zu setzen, einfach auf das Wort davor tippen! Das Bilderpuzzle dient als wertvolle Motivation und Erfolgskontrolle! Die App funktioniert nach dem Prinzip der Lernkartei. D.h. jede richtig gelöste Aufgabe wandert in die nächste Box - jede falsche Antwort führt zurück in Box 1. Wenn eine Aufgabe in Box 5 oder größer ist, wird davon ausgegangen, dass es verstanden ist. Entsprechend Erkenntnissen aus der Hirnforschung werden die Aufgaben nicht einfach sequentiell aus den Boxen genommen, sondern nach einem ausgeklügelten Algorithmus zeit- und lernstandsabhängig aus allen Boxen ausgewählt. Tippe auf die Fläche unter dem Balkendiagramm um die Auswahl der Aufgaben zu ändern. Berühre die Note um Details des bisherigen Übungsverlaufes zu sehen.

DE Flow makes German come alive — as sound. Built for learners from A1 to B1, the app transforms word order, verb conjugation, and grammatical gender into an audiovisual experience powered by a real-time synthesizer engine. SYNTAX SEQUENCER Build German sentences by dragging word blocks into a sequencer strip. Each word type has its own synth voice — nouns sound different from verbs, articles from adjectives. Correct sentences play as consonant melodies; mistakes trigger dissonance — tritone shifts, microtonal jitter, noise bursts. You hear the error before you read the explanation. INTELLIGENT FEEDBACK The Interference Radar detects errors rooted in your native language (English or Traditional Chinese) and shows targeted contrastive tips. Word order mistakes get dynamic, context-specific feedback: the app names the exact words you misplaced and explains the V2 rule with your own sentence. GENUS COLOR SYSTEM Every noun is color-coded by grammatical gender — Electric Blue (der), Neon Pink (die), Radioactive Green (das) — reinforced by distinct synth tones so you learn gender through both sight and sound. WORD TYPE SONIFICATION Nine word types — noun, verb, adjective, adverb, preposition, conjunction, pronoun, particle, number — each mapped to a unique waveform, frequency, and neon color. A live oscilloscope visualizes the audio in real time on vocabulary cards and during sentence playback. AMBIENT LEARNING Eight generative ambient tracks in the tradition of Berlin School electronic music accompany your study sessions. Six tracks follow the classic three-layer structure (pad, sequencer, bass). Two tracks — Nebelmeer and Zwielicht — add a fourth voice: a synthesized trumpet with a slow, swelling attack that evokes reversed tape recordings — no samples used. THREE SPEECH MODES Choose how vocabulary is spoken: Standard (clear TTS), Analog-Signal (genus tone + warm-filtered speech + echo cascade), or Synthwave-Echo (clear voice + filtered delay). NERD MODE A retro control console with ~38 tweakable parameters: filter cutoffs, ADSR envelopes, mix levels, trumpet voice parameters, and speech processing — all visualized through rotary knobs, faders, and VU meters. Hit RND to generate random settings and hear the result instantly. Reset to curated defaults at any time. WHAT'S INSIDE - 3 free lessons to get started — unlock all 45 with a single purchase - 45 lessons across A1, A2, and B1 — from greetings to B1 grammar (Konjunktiv I, Passiv, Diskursmarker) - Level filter: browse lessons by A1 / A2 / B1 - Syntax exercises, vocabulary cards, grammar explanations with contrastive notes (EN & zh-Hant) - Composita Builder with English and Chinese language parallels (handbag = hand + bag ↔ die Handtasche; 再見 = 再 + 見 ↔ Wiedersehen) - XP system, learning streaks, mastery tracking - All features included free: speech modes, ambient music, nerd mode - No internet required — fully offline - No ads, no tracking Designed for Taiwanese learners studying German for university or work in the DACH region — but welcoming to anyone who wants to experience language learning differently.
