5. The phases of mHealth software development

5.1. Designing the user interface

Use a systematic approach to design and test content and the user interface by employing User Experience (UX) testing in all stages of the product life-cycle (Davies & Mueller, 2020). If the product is designed in a way that is easy to use, enjoyable, and contains useful information, the app's uptake will be a success (Davies & Mueller, 2020). Consider rapid prototyping to design an appropriate user interface to test the product's coverage, software, and usability. (Punchoojit & Hongwarittorrn, 2017; Yanxia et al., 2020). Some examples of UI prototypes are included below:
