The classic way to develop is to hire programmers. But there is also an option when you create an application yourself, using special services. Let's consider both.

Development with a programmer
It can be either an individual freelancer or an entire agency - the choice will depend on the complexity of the application and the size of the budget.
The method is suitable for teams that have a developer on staff with the relevant experience or money to hire one.
Before hiring a specialist from the outside, make sure of the experience - ask for examples of work. Ideally, these should be examples in your topic, such as shopping or booking tickets.
Zero-code app builders
For those who do not know how to program, there are services on the market for creating applications on their own - the so-called no-code or zero-code services. You will receive a selection of such services with a description and prices later in the article.
Zero-code services work on the principle of constructors: you assemble an application from an existing set of elements and functions, create your own design. Traditionally, there is a set of ready-made templates that you can adapt to your needs.
The functionality of these services directly depends on the tariff. On free or cheap, a minimum of functions is available. Most likely, to create a high-quality native application for iOS and Android, you will have to buy a more expensive tariff, but it can be cheaper than attracting a developer.
