First of all, deny that the application on Apple's mobile phone can not only be installed and downloaded through the App Store. AppStore is Apple's official App Store, that is, App can acquire users and promote operations through App Store. However, Apple's shelves are not free. After the application is successfully put on the shelves, the application downloaded through the App Store has trading behavior, and Apple officially wants to draw it. I drive quite a lot of this road, but it is understandable to keep the appearance of buying road money. There is a charge for this kind of behavior. After all, there is no app to provide users with a download channel.
But this channel is not the only one. Another official download method of Apple's application is popular recently, which is Apple's TF signature. Because Apple's TF signature is a beta version, the review of the application is much looser than that of the normal App Store. Use testflight to help developers test the beta version of the application, and all invited testers can access the build version provided by developers. In other words, the App can download and install applications through Apple's TF signature, which is also Apple's official approval method, but it is the official "application store" of Apple's internal testing. After the application was signed by Apple's TF, there were theoretically 1W downloads in three months. Although it seems that there is a time limit, it can continue to increase if it is used normally, which is more stable than other Apple signature methods used in internal testing.
Apple apps need to be downloaded and installed, and it's not just the App Store that can be downloaded. Other ways of testing Apple's signature, such as Apple's TF signature, are also an option provided by app operators for users to download. In the current market environment of ios game apps, Apple's TF signature is more suitable for operators.
