Tieng Viet Lop 1 - Tap 2 is an Android application that simulates the Vietnamese language textbook for first graders, published by the Ministry of Education and Training. Developed by Tracy Duong, this free educational tool aims to support children who are about to enter first grade and first-grade students, as well as assist parents in teaching their children. The software provides illustrations for each character, making it easier for children to understand and memorize the lesson.

The app contains the entire content of the textbook, including 20 phonics lessons, 13 topics, 491 words, phrases, poems, and stories, each with corresponding illustrations and audio recordings. The software allows users to quickly and easily search for specific lessons and provides a handwriting font to help children practice writing. While it is not a complete replacement for the textbook, Tieng Viet Lop 1 - Tap 2 is a helpful supplement for young learners.
