Social media has negative effects on people’s emotions and social well-being by raising or reducing their self-awareness. We then designed a personal informatics tool, which is a usage report that guides users to learn about their posting activities and self-reflect. With the exact data extracted from users’ social media along with the data analysis we did, we could provide an easy, enjoyable, and heart-warming way for them to deeply self-reflect, including reminding them of their good memories and highlight moments, giving them numbers and visualizations, etc. Users can make adjustments accordingly to experience more positive social well-being.
