What does the development of mobile applications not typically include?

The development of mobile applications primarily focuses on creating software tailored for smartphones, which includes designing user interfaces and ensuring an optimal user experience. Thus, options like creating software for smartphones, designing graphics and user interfaces, and connecting with cloud services are all integral components of mobile app development.

Building infrastructure servers, however, is not a typical part of mobile application development. This function generally falls under the domain of backend development or system administration. While mobile apps may rely on server infrastructure to store data or provide services, the direct task of building and managing that infrastructure is separate from the core responsibilities of mobile app developers. They usually focus more on the application layer rather than the server layer, which makes this choice the one that does not fit within the usual scope of mobile app development.
