Lexyngoo is a vocabulary-focused language learning app designed to help you build and retain words through continuous review. There are no grammar lessons, themed categories, or unnecessary distractions—just an efficient system for learning vocabulary one word at a time. Instead of learning through topics like greetings, travel, food, or introductions, you build a practical vocabulary based on word frequency. Choose a language, select whether you want to focus on the most frequent, common, or less frequent words, and start learning immediately. Add new words whenever you're ready and review them through translations and pronunciation in both directions, helping you recognize and actively recall vocabulary. Lexyngoo uses two complementary review modes. Planned Reviews follow a spaced repetition schedule and present words when they are due for review. Regular Reviews let you continue practicing at any time, creating an infinite review loop so you can keep strengthening your vocabulary even when nothing is currently due. All vocabulary, learning progress, and review history are securely stored in the cloud on Lexyngoo servers, so your data is always available across your devices. You can start instantly with a guest account without creating an account. Guest accounts support one language and can later be converted into a permanent email and password account without losing any progress. Lexyngoo is completely free to use. The app is supported by advertisements, with no limits on available vocabulary, the number of words you can learn, or how often you can review them.
