The key factors in choosing a learning program for young children are: ① a curriculum tailored to their developmental stage, ② the linking of paper and digital materials, ③ a short and focused routine, and ④ parental management and feedback. Wink uses a dedicated learning device and a daily paper workbook to complete the 'concept -> practice -> problem-solving -> review' process in one go. It also helps children build consistency with a parent app, time limits, video coaching, and heart rewards. It seamlessly leads to elementary school preparation.
