Persuasive features are often used in food journaling apps to help people reach various personal goals. Our understanding of persuasive design in food journaling apps has primarily been built from studying and designing apps in Western contexts. However, varied cultural perceptions around journaling goals, such as healthy eating and weight management, suggest that the design of persuasive features may differ across cultures. We therefore investigate how culture influences the use of persuasive techniques in Chinese food journaling apps and consequently people’s journaling experiences. Through reviewing features of Chinese apps and interviewing people who have used them, we find that some Chinese apps heavily emphasize body shape, and people’s motivations for journaling and desires for journaling apps similarly focus more on body shape than diet. We discuss tensions and opportunities for food journaling apps which align with or account for cultural norms while challenging unhealthy or problematic aspects of them.
