Native Application is written in a particular programming language to work with a specific Operating system. A larger part of smartphones either run an Android operating system or iOS in event that it’s an apple device. Native Applications are explicitly built for the specific operating system to take advantage of the functionalities of the devices that run the particular operating system. And hence native applications can’t be utilized on different types of operating systems. In other words, iOS applications can’t be utilized on android telephones as well as the other way around. Since they are explicitly built for a specific operating system the programming languages that the applications are built in are also specific to the OS.
