We are a team of two developers with a keen interest in learning Chinese. We created Lychee.study as a hobby project to help others learn Chinese in an efficient and enjoyable way. Your feedback and suggestions are welcome at hello@lychee.study. Lychee.study is a Chinese learning app with a focus on writing. You can study using predefined word lists (HSK 1-6) or create your own custom lists. Each word you study is saved in a recommendation system powered by a spaced repetition algorithm, ensuring optimal retention. Track your progress continuously and compare it against standardized language levels. The app works offline and offers a variety of features, including a dictionary, character composition information, and pronunciation support. We're actively developing more exciting features.
