With the rapid dissemination of mobile technologies, along with hectic life nowadays, consumers are more in favor of food delivery apps (FDA). However, many aspects related to the usage of FDAs have not been fully unearthed. Drawing upon the trust transfer theory, the study theorizes the consumer’s trust formation in FDA and investigates the antecedents of trust to platform and trust to a merchant that mediates the continuous usage intention and purchase intention. The proposed framework was tested through structural equation modeling (SEM) based on an online questionnaire. The findings illustrate the trust transfer mechanism in the context of the FDA and its effects, which have both theoretical and practical implications for different stakeholders.
