Tools and tools for mobile application development are different and numerous. Only correctly chosen architecture will help to save efforts, time and own finances. Two approaches are considered to be the main ones here. These are cross-platform and native. Regardless of this, another one is developing, which is the progressive approach.

Native development is presented in the guise of separate software for any mobile platform. In other words, one app is created for Android, and another for iOS. The advantages of such a solution should definitely include:

Availability of a responsive, fast and maximally reliable interface.
Full support of all functionalities of your smartphone. This should include not only internal purchases, but also priority updates, as well as access to geoservices.
Expanded features that relate to the design.

The cross-platform approach implies the ability to develop a common code base, simultaneously for 2 platforms. The code is then translated through a layer on any OS. The advantages include:

A single code base. The correctness of functioning on any platform is guaranteed. This greatly simplifies the logic and makes it possible to avoid all sorts of errors.
Reducing the time to create and the cost of the application.

Recently, progressive applications have also become popular. They are presented in the form of a hybrid, which combines the qualities of a mobile application and a conventional site. The advantages include:

Lower cost of creation, unlike when classic approaches are used.
The absence of a large number of intermediaries presenting themselves in the guise of stores.
