Tieng Viet 1 Canh Dieu - Tap 2 is a free educational software application available for Android devices. Developed by Tracy Duong, this app is designed to support the learning of Vietnamese language for children who are about to enter primary school and for primary school students. The app is based on the textbook "Tiếng Việt lớp 1 - tập 2" by Nguyen Minh Thuyet and provides a simulation of the textbook's exercises.

The app has a range of features to support language learning, including displaying the content of each lesson in the textbook, pronunciation of individual words, phrases and sentences, and reading stories based on the pictures in the textbook. The app is ideal for parents who want to support their children's learning at home. However, it is important to note that this app is only suitable for those who have a basic understanding of the Vietnamese language and are able to read and write.
