We developed and tested a catering apps success model that integrated the EC systems success model and relevant product marketing and customer loyalty variables. The empirical results partially support the transfer of Wang’s (2008) EC systems success model to the catering app context. More specifically, the EC systems success model can be divided into two sub-models: the quality–value–loyalty path and the quality–satisfaction–loyalty path. The results support the quality–value–loyalty path but only partially support the quality-satisfaction-loyalty path. This result may be due to information quality and service quality not influencing user satisfaction, which might be attributable to users’ different reasons for using different types of apps.
