Mobile App Development

A software application developed for use on Apple's iOS-powered iPhone devices. iPhone apps are available through the Apple App Store and are designed to run on Apple's iOS mobile operating system, which powers the iPhone as well as Apple's iPad and iPod Touch devices. Apple encourages developers to program their own iPhone apps for download through the App Store, and the company has released an SDK with sample code projects to help developers get started. iPhone apps in the App Store can be freely downloaded or purchased by users, with revenues for the latter shared between Apple (30%) and the software developer (70%). Support for in-app purchases in iPhone apps offers developers an additional revenue option.
Android software development is the process by which new applications are created for devices running the Android operating system. Google states that[3] "Android apps can be written using Kotlin, Java, and C++ languages" using the Android software development kit (SDK), while using other languages is also possible. All non-JVM languages, such as Go, JavaScript, C, C++ or assembly, need the help of JVM language code, that may be supplied by tools, likely with restricted API support. Some programming languages and tools allow cross-platform app support (i.e. for both Android and iOS). Third party tools, development environments, and language support have also continued to evolve and expand since the initial SDK was released in 2008.
