Cross-platform mobile application development continues to gain popularity. This is due to the sharp rise in the creation of native software products that do not always bring the expected results. For instance, a cross-platform application can run on multiple operating systems, including Windows, Linux, and Mac OS X. Below, we will discuss cross-platform development and the tools to create multi-platform applications. 
It is worth considering that creating a high-quality cross-platform application without high-level programming languages is impossible. Choosing the right development environment that supports conditional compilation is also crucial. The principle of multi-platform development is based on using a single code base, ensuring compatibility with different platforms. Stability is achieved by timely and correct translation of the application code under a certain operating procedure.
