The main feature of the development of a mobile application, unlike the development of a website – is the limited size of the screen of a smartphone or tablet. In this regard, one of the main tasks that the developer faces is to reduce the number of clicks on the screen to perform the operation and compactness – User Experience. Also, the most important task is to ensure the speed and volume occupied by the application in the device's memory.
Native applications are called because they are written in the native programming language for a particular platform. For Android, this language is Java, whereas for iOS-objective-C or Swift. Native applications are located on the device itself, you can access them by clicking on the icon. They are installed through the app store (Play Market on Android, App Store on iOS, etc.).
They are designed specifically for a specific platform and can use all the features of the device-a camera, a GPS sensor, an accelerometer, a compass, a contact list and everything else. They can also recognize standard gestures that are pre-installed by the operating system or completely new gestures that are used in a particular application.
Due to the fact that native applications are optimized for a specific OS, they fit seamlessly into any smartphone, featuring high speed and performance. Native applications can access the device's notification system, and, depending on the purpose of the native application, it can completely or partially do without an Internet connection.
