DE Flow
Read full descriptionHide full description
DE Flow makes German come alive โ 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 โ nouns sound different from verbs, articles from adjectives. Correct sentences play as consonant melodies; mistakes trigger dissonance โ 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 โ Electric Blue (der), Neon Pink (die), Radioactive Green (das) โ reinforced by distinct synth tones so you learn gender through both sight and sound. WORD TYPE SONIFICATION Nine word types โ noun, verb, adjective, adverb, preposition, conjunction, pronoun, particle, number โ 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 โ Nebelmeer and Zwielicht โ add a fourth voice: a synthesized trumpet with a slow, swelling attack that evokes reversed tape recordings โ 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 โ 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 โ unlock all 45 with a single purchase - 45 lessons across A1, A2, and B1 โ 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 โ die Handtasche; ๅ่ฆ = ๅ + ่ฆ โ Wiedersehen) - XP system, learning streaks, mastery tracking - All features included free: speech modes, ambient music, nerd mode - No internet required โ fully offline - No ads, no tracking Designed for Taiwanese learners studying German for university or work in the DACH region โ but welcoming to anyone who wants to experience language learning differently.

Learn German grammar by playing! DEtris is a visual learning game for German grammar. The game teaches sentence structure using colors and pattern recognition. You get an English sentence. German words drop from the top. Slide each one into its color zone: yellow for the subject, green for the verb, blue for the object. Lock it in before it lands. Complete the sentence and it clears. Why DEtris? Word order and articles are what trip up most German learners. DEtris drills both without a single grammar table. Instead of memorizing rules, you place words under time pressure until the pattern starts to feel obvious. Inside DEtris: - A four-step tutorial before your first game - 210 sentences with changing word and article options, so no two runs play out the same - Speed rises every ten sentences, capped so it never becomes unplayable - Streak multiplier with its own color ladder - Three lives per run and a high score to beat - Eight background tracks you can switch any time - Sound, haptics and ghost piece, each toggled separately DEtris works fully offline. No sign-up, no ads, no tracking, no analytics. Nothing you do leaves your device. Built for A1 and A2 learners and for players who just want a puzzle with something inside it.
