Native apps are developed specifically for one platform, using the development tools and language that the respective platform supports (e.g., Swift and Xcode for iPhone, Kotlin and Android Studio for Android). These apps can maximize performance and take full advantage of all the device features, such as the camera, the GPS, the accelerometer, the compass, the list of contacts, and so on. They offer fast performance and a high degree of reliability. They also have access to a phone’s various devices, such as its camera and address book. However, they can be costly to develop if you want to serve more than one type of device.

2. Hybrid Apps

These apps entail the creation of a single app that can run on multiple operating systems, like Android, iOS, and Windows. Hybrid mobile apps are developed using multi-platform web technologies (for example, HTML5, CSS, and JavaScript). Hybrid apps are essentially web apps that have been put in a native app shell. Once they are downloaded from an app store and installed locally, the shell can connect to whatever capabilities the mobile platform provides through a browser that's embedded in the app. The main benefits of hybrid apps are the portability they offer across platforms and the low cost of development.
