Native apps are software applications that are specifically designed and developed for a particular mobile device operating system (OS), such as iOS or Android, using the platform's native programming languages and tools. Native apps are installed directly onto the device and can be accessed through the device's home screen or app launcher.

Native apps offer several advantages over web apps or hybrid apps, including improved performance, enhanced user experience, and access to the device's hardware and software features, such as the camera, microphone, and GPS.

However, developing native apps requires specific knowledge and expertise in the programming languages and development tools of each platform, which can increase the cost and time required for development. Additionally, each app must be developed separately for each platform, which can be time-consuming and expensive.

Overall, native apps are a popular choice for businesses and developers who prioritize performance, user experience, and access to device features, but they may not be the most efficient or cost-effective solution for every use case.
