Technology, like the rest of the world, is rapidly evolving. Mobility is the order of the day in today's environment. Mobility is, of course, a primary concern for companies, as is the development of apps for major platforms, as this adds to the organization's branding and profitability.
Native development for platforms such as iOS, Android, and Windows, on the other hand, remains a difficulty due to cost and time constraints. Since the core codebase isn't platform-independent, the cost of developing a mobile app is likely proportional to the number of platforms the company supports. Not to mention the additional costs associated with recruiting the essential skill sets for mobile app development.
