A mobile app for the prevention of cardiovascular disease and type 2 diabetes was developed and refined through user testing to improve usability and functionality.
We developed the app using behavior change theory and scientific evidence. The user testing allowed us to identify and remove technical errors and integrate additional functions into the app, which the participants had requested. Next, we will evaluate the feasibility of the revised version of the app developed through this design process and usability testing.
Buss et al. (Tue,) studied this question.
