Hán - Việt Từ Điển is a dictionary application developed by Trần Anh Vũ for Android devices. The application aims to assist in the translation of Buddhist texts using data from two commonly used dictionaries: Lạc Việt and Thiều Chửu. It is worth noting that this application is specifically designed for the purpose of translating Buddhist texts and may not be suitable for other advanced usage.

The application offers five search features, namely, Hán - Việt pronunciation search, Pinyin pronunciation search, Hán character search, search within meanings, and stroke count search. The application uses a specially designed algorithm to process data, resulting in fast and efficient word search. The data is stored within the application, and no internet connection is required for its use. The application does not collect any user data.
