Cross-platform application development is the process of creating an application that can run on multiple operating systems and use different programming languages. Cross-platform applications are usually not as powerful as native applications, but they are more flexible because they can be accessed from any device that has an Internet connection. Native apps are developed for a specific platform, such as iOS or Android. They use the features and functionality of that particular platform and cannot be used on another platform (unless they are ported). Cross-platform applications are developed using the same code base and are deployed on different platforms. They can run on multiple operating systems or devices.
