What is the difference between Cross-platform development and Native App development?
Native apps are developed specifically for a single platform like Android or iOS. The native apps can only be built using languages that are compatible with that particular platform. Native Android apps are built using Java and native iOS apps are built using Swift and Objective C. Native apps are not compatible with any other platforms. You will have to build separate apps for each one.
Cross-platform apps on the other hand are compatible with multiple platforms and require only a single development process and codebase. They are built using web development technologies like HTML and CSS which are platform independent.
