A native mobile application is an application written in a specific language developed for use on a particular platform or device. Native applications have a lot of advantages since they are built to work with the operating system and have access to a wide range of built-in features. They also come at a high cost since each native application must be maintained separately. Many companies cannot afford to provide these types of applications across all devices.
React Native is a perfect choice for companies who want to give their customers a native experience but still save time and money by being able to share a code base and not have multiple teams of developers working on different platforms.
