Different types of apps are used for different reasons. When consumers use catering apps, their main goal is to place an order in an efficient manner, which requires an easy to use and stable system (Business Insider, 2015). If consumers cannot accomplish the main goal, they tend to feel dissatisfied. Hence, system quality is a key determinant factor of user satisfaction. On the other hand, because product information, personalized service, and transaction safety are secondary to the main goal of using catering apps, the effects of information quality and service quality on user satisfaction are less salient. If the context is online shopping, both information quality and service quality, in addition to system quality, may be important determinants of user satisfaction because the main goal is to find a product from among many sellers that best fits the user’s personal needs and can be purchased safely.
