With the proliferation of the Internet and wireless technology in many areas of people's life; the use of mobile phones; especially smartphones for health practices and information (mHealth) has increasingly been prevalent. Based on Technology Acceptance Model (TAM) and the Innovation Diffusion Theory (IDT); this study examined the role of mHealth literacy and other factors toward the adoption of wellness apps among the users in Danang city. The results confirmed the impact of mHealth Literacy on (1) intention to use health apps (2) the perceived usefulness and (3) the perceived ease of use. While the perceived usefulness and the perceived ease of use are found to exert influence on the intention of use; the role of privacy and security concerns on intention to use was rejected.
