With the help of mobile designers, you can develop applications with different functionality. You can choose a universal service or a designer sharpened to create applications of a certain type.
Such services have the designation low-code or no-code, which indicates the possibility of creating a product according to a template with minimal or no programming at all (from ready-made blocks). If your business does not involve its own development department, then you can try solutions without code. To get the most out of the functionality, it's still worth learning a little about languages and development platforms.
Today, when foreign platforms, if not closed to Russia, then lose the ability to pay for their services, it is worth paying attention to Russian services for creating mobile applications.
