The name "app store" is not absolutely correct. It is difficult to imagine outlet in which from 30 to 70 percent of names of goods would be distributed free of charge. And mobile "shops" are that unless "goods" in them are non-material. Certainly, it is necessary to pay for downloading of programs Internet access all the same therefore it is better to select an unlimited rate.
From the technical point of view the mobile app store represents the program which is a part of a firmware of the smartphone. Before its use the client should undergo simple registration procedure in the application or in the browser of phone or the computer. After that the login and the password for a login to the account is assigned.
Having started shop and having entered the account information, the user has an opportunity of viewing the list of available applications. He can select in him different categories, and sometimes and subcategories. It is also possible to look for applications by keywords and phrases.
Having selected the pleasant program, the user obtains data on its cost at once.
