Cross-platform applications are characterized by being created with a single programming language that facilitates their visualization on any type of device regardless of its operating system. Since there is no need to make different applications for different platforms, developers can build and publish the applications on multiple app stores simultaneously. Cross-platform mobile development is the creation of software applications that are compatible with multiple mobile operating systems. Originally, the complexity of developing mobile apps was compounded by the difficulty of building out a backend that worked across multiple platforms.
