BUILDeutsch
Read full descriptionHide full description
BUILDeutsch makes German click. Most apps make you memorize German. BUILDeutsch shows you how it actually works — every word colored by its role in the sentence. It's intuitive one-of-a-kind color-coding engine helps you finally understand sentence structure. Der is cyan, die is magenta, das is lime. Verbs glow yellow. Cases have their own colors. You don't memorize tables. You build sentences and quickly the patterns become instinct. THE BUILDER — Enter any sentence to see how it's built, then reshape it. Tap a word to change tense, case, or person, and watch the rest of the sentence rearrange itself the way German demands. DIALOGUE — Real conversations from everyday life: a family morning, the bakery, a doctor's visit. Two native voices, every word colored by its role, the English right underneath. Listen, read along, and say the lines back. DEUTSCHLENS — Point your camera at your kitchen, your street, your desk — and see the world in German. Every word arrives with its gender, its plural, and a natural sentence for practice. Saved photos keep their words offline, forever. SATZPUZZLE — Rebuild real German sentences piece by piece until the word order stops feeling foreign and starts feeling obvious. DER WEG — A complete A1 → C1 course, 84 lessons, one path. The color code is introduced one idea at a time: verbs first, then genders, then time, then the case system — exactly when the grammar itself does. Listening, speaking and reading woven in. WORKING IN HEALTHCARE? — There's a Medical German section too — 1,800+ clinical terms and common sentence patterns from Anamnese to Arztbrief. It's not a formal FSP prep course, but if the Fachsprachenprüfung is on your horizon, it's a great companion for building the vocabulary along the way. AND THE REST • 7,000+ words with genders, plurals and example sentences — searchable offline • Flashcards with spaced repetition, organized by real-life topics • Build your own decks from any word you meet — even from your photos • A cheat sheet for the moments you just need the answer • A night theme that's easy on the eyes FREE: the first two course units, daily photo credits, and the full color-coded experience. PRO: the complete A1–C1 course, unlimited DeutschLens photos, unlimited Builder sentences. $7.99/month or $49.99/year, each with a 7-day free trial. Subscriptions auto-renew unless canceled at least 24 hours before the period ends; manage in your App Store account settings.

Learn German from real videos you'd actually want to watch — matched to your level and listening speed. Reelang turns the clips native German speakers actually post into listening practice you can scroll. Hear German from Germany, Austria and Switzerland, from clear beginner-friendly speech to full native pace. How it works • Germany, Austria and Switzerland, each labelled, so you always know what kind of German you’re hearing. Swiss German and Austrian German are not an afterthought — each is its own feed with over a thousand clips, and Bavarian and Swabian are there too. • Real German videos, made for German speakers, not for textbooks. • A feed graded two ways: by your level, and by how fast people actually speak. • Smart Subtitles underline the words worth learning — the most common 500, 1,000 and 2,000 words in German — so you can see at a glance which word is worth a tap. • Tap any word in the captions to see what it means, right there in the sentence. • Learner insights with Reelang+: short notes on the German worth knowing in a clip. Focus mode, the guided way in New to German? Do not just watch a clip, work it. Focus plays it once with no text, asks how much you caught, then takes it sentence by sentence and word by word until it lands. Tap a word to keep it for review. Prefer to just watch? Flow does that instead. Start at the beginning and the feed meets you there. It opens with the easiest German it has and speeds up as you do. Some videos have the subtitles burned into the picture. A normal player cannot take those off the screen. Reelang can. Hide them and you are only listening, not reading. You're not memorising lists. You're hearing German the way it's really spoken — fast, casual, alive — and understanding a bit more each day. That's when it stops feeling like homework. Free to start. Scroll, tap, learn. — — — REELANG+ (OPTIONAL) Reelang is free to use. Reelang+ is an optional upgrade that adds: • Learner insights on the words and phrases worth knowing in a clip • Word translations into your own language, not only English • A feed built around your interests • Vocabulary that returns in new clips, so it sticks Reelang+ is available as an auto-renewing subscription.
