Apps for Android and iOS are developed in two different languages and uses native libraries provided by Google and Apple. This provides a number of advantages over access and utilisation of hardware and operating system software. Such apps are called native apps. Some apps works on both platforms, those are named hybrid or cross-platform apps. A cross-platform app is cheaper to develop, since it work for both Android and iOS, but often it is less efficient and has less functionality.
