These findings suggest that developers looking to create successful apps should focus on creating apps that fall within the Family, Games, Tools, Medical, Business, or Productivity categories, as these categories represent the majority of apps in the marketplace. However, it is important to note that there is still a significant percentage of apps that fall outside of these categories, with Other representing 11.18% of all apps. Therefore, it may also be worthwhile for developers to explore less popular categories to find a niche market. Understanding the distribution of apps across categories is an important first step in identifying where there may be opportunities for success in the app marketplace.
