Thước Lỗ Ban is a lifestyle app developed by GTSStar.co for Android devices. This free app is based on the Lỗ Ban ruler, a tool used in ancient China to measure the good or bad energy in feng shui for houses, furniture, and other objects. The app allows users to measure and adjust the size of furniture and objects to bring more luck and prosperity into their homes. Thước Lỗ Ban comes with three rulers, each measuring a different length, and is suitable for various purposes, such as architecture, construction, and furniture making. With this app, users no longer need to carry a physical ruler and can conveniently use their smartphones to measure and adjust the size of objects. Thước Lỗ Ban offers users precise measurements and helps them choose the most suitable measurements for their homes.
