Factors used to Influence Mobile Health Application Rating

The data collection phase started with selecting appropriate apps to provide the proof-of-concept. The apps were searched using the keywords "heart disease", "heart related medical app", "healthy heart", "heart care" in the Google Play Store and Apple store to evaluate the proposed AI-based app rating scale. A total of 317 applications in different categories have been identified based on the search criteria. Each app was initially qualitatively assessed and screened with titles, descriptions, and associated screenshots provided in the Play Store. Out of the total 317 m-Heath apps, 278 are from the Google Play Store while, 39 are from the Apple Store. Then, we set some exclusion criteria for apps, such as duplicate apps, apps not related to heart disease, apps downloaded less than 5000 times, game and simulation apps, apps not updated in more than 12 months, and non-English apps. Consequently, after filtering based on all these criteria, we selected 43 apps (23 apps from Google Play Store and 20 apps from the Apple Store).
