Lingvist: Learn Languages Fast is an Android-based educational application developed by Lingvist Technologies OÜ. It is designed to make the language learning process faster, easier, and more effective. The app offers courses in French, Spanish, German, Russian, Portuguese, Italian, Dutch, Japanese, Korean, Estonian, and English grammar.

Lingvist uses an intelligent spaced repetition algorithm that predicts the user's current level and identifies which words will be most useful to learn next. The app provides context sentences with translations to help users better understand how to use what they learned. Lingvist also offers customization options, allowing users to create their own decks from words, texts, or even an image.

The app is portable, and data is saved and synchronized across web and mobile platforms. It also offers voice input for hands-free use. Lingvist is available in 11 different languages: English, eesti, Français, русский, Deutsch, Español, Português, 日本語, 简体中文, and 繁體中文. The app offers a free trial period, and subscriptions provide access to all language courses.
