Native apps are characterized by the fact that they are specially adapted to the target platform. Because a native app directly uses the programming interfaces (APIs) of the target platform, the bandwidth of the applications is very high. In addition, all platform-specific hardware and software functions can be accessed, such as files, GPS, acceleration sensors, microphone and camera. Due to the various software platforms, however, it is not possible to play an Android app on an iPhone or vice versa. Thus, a software company must individually develop the application for each terminal. Each mobile platform has its own software development kit (SDK) and its own integrated development environment (eg Android Studio or Xcode), which can be used by developers. The preferred programming languages for the largest systems are:

Java for Google’s Android
Objective-C and Swift for Apple’s iOS
C #, C, and C ++ for Microsoft Windows
HTML5 and JavaScript for Mozilla’s own operating system Firefox OS
With native apps, all types of devices can be served at once, all based on one platform. With the Universal Windows Platform, it is possible to write native Windows apps for desktop PCs, laptops, tablets, smartphones and the Xbox One.
