Vô Vi is a comprehensive collection of audio, video, and text documents centered around the Vô Vi philosophy and meditation method. This app features teachings from Master Lương Sĩ Hằng and spiritual guide, Master Đỗ Thầu Hậu. The content includes meditation methods, lectures, transcripts, poems, Q&A sessions, and more, catering to Vietnamese practitioners.

Master Lương Sĩ Hằng's passing in 2009 left behind a treasure trove of invaluable documents, with ongoing additions to the app. While primarily in Vietnamese, some content is available in English and French, with plans for further translations. Designed for iPhone, the app offers a curated selection of documents for an enhanced viewing experience.
