qianxia software (www.qianxx.com) co., ltd. believes that the two basic profit models of APP development are built-in advertising and direct charging. Of course, there are also in-app purchases, but in-app purchases are not suitable for all applications, but more for content consumption and games.

One of the advantages of the built-in advertising model is that it can attract a large user group. After all, everyone is willing to try something free. There may be two kinds of such applications, one is that there is only a free (advertising) version. Its profit is at the expense of user experience, and advertising charges are more uncertain than direct charges, and high download volume does not mean profit. Many users will not click on advertisements.
