Mobile App Rating Scale (User Version) for the assessment of a community health worker medical application

The study demonstrated the effectiveness of the extreme prototyping framework in developing a medical mobile app and the utility of uMARS as a guide for authoring high-quality mobile health apps. The uMARS metrics were beneficial in setting developer expectations, identifying strengths and weaknesses, and guiding the iterative improvement of the app. Further assessment with more CHWs and patients is recommended.
