Lang Lern is a flexible language-learning app built around hands-free vocabulary practice, active recall, natural lessons, and real understanding. Most language apps require you to constantly look at your screen. With Lang Lern, you can choose a vocabulary deck, press play, and continue learning while working, walking, cleaning, exercising, or commuting. Hands-Free Vocabulary Lang Lern speaks each word twice, waits a few seconds for you to remember or guess the meaning, and then reveals the translation. Choose which language comes first: • English first • The language you are learning first Practice listening or active recall without repeatedly touching your phone. Focused Vocabulary Decks Explore bite-sized decks covering subjects such as: • Family • Animals • Food and fruit • Landscapes and nature • Common verbs • Everyday objects • And more Use premade decks or create your own collections based on the vocabulary you want to learn. More Ways to Practice Review the same words through different activities: • Multiple choice • Word matching • Crosswords • Word-find puzzles • Hands-free audio • Self-assessment tests Each activity strengthens a different part of your vocabulary, from recognition to recall. Track What You Know Take a vocabulary placement test to see which words you already understand. Reveal each translation and rate yourself: • Yes I knew it • Almost I nearly remembered it • No I did not know it Lang Lern tracks the words you know, the words you are currently learning, and the words that need more practice. Natural Language Lessons Move beyond isolated vocabulary with lessons built around useful sentence patterns. Learn how to form natural sentences step by step, recognize repeating structures, and develop an intuition for how the language works without starting with long grammar explanations. Sentence and Grammar Viewer Explore example sentences and select individual words, endings, or particles to understand: • Their meaning in context • Their role in the sentence • How words connect • Why the sentence is structured that way • Other examples using the same pattern Lang Lern helps reveal the smaller pieces that create meaning while keeping them connected to real sentences. Key Features • Hands-free automatic vocabulary playback • Timed recall before translations • English-first or target-language-first audio • A growing selection of languages • Bite-sized premade vocabulary decks • Custom vocabulary decks • Multiple-choice and matching games • Crosswords and word-find puzzles • Vocabulary placement testing • Yes, Almost, and No progress tracking • Natural sentence-building lessons • Word, particle, and grammar explanations Lang Lern is not limited to one learning method. Use it as an audio trainer while your hands are busy, a vocabulary game during a break, or a complete lesson system when you have time to focus. Turn listening time into learning time.
