The development of mobile applications is the set of processes and procedures involved in writing software for small wireless computing devices, such as smartphones or tablets.
The development of mobile applications is similar to the development of web applications, and has its roots in more traditional software development. A key difference, however, is that mobile apps (apps) are often written specifically to take advantage of the unique features offered by a particular mobile device. For example, a gaming app could be written to take advantage of the iPhone’s accelerometer.
One way to ensure that applications show optimal performance on a given device is to develop the application (app) natively on that device. This means that, at a very low level, the code is written specifically for the processor of a particular device. When an app needs to run on multiple operating systems, however, there is little-if any-code that can be reused from initial development. The application must be essentially rewritten for each specific device.
In the future, most mobile app development efforts are expected to focus on creating browser-based apps that are agnostic of the device. Browser-based applications are simply websites created for mobile browsers. These sites are built to quickly load through a cellular network and have easy-to-use navigation with your fingers.
