One of the novelties that will be available starting with iOS 7 but it has not yet reached the attention of all users, it is related to in-app purchases, an extremely important component of App Storeof the It looks like Apple will give them developers the opportunity to offer free in-app purchases for the users of the applications, more precisely certain content will be accessible for free directly from the applications. Each in-app purchase can have a maximum of 2 GB of content, with Apple hosting and distributing it to users.
In-app purchases generate the most money for app developers for the iOS platform, and this new system allows developers to reduce the initial size of apps that are downloaded from the App Store. Unfortunately, each developer has to implement this system separately in their own application, so don't expect it to be used by everyone right from the start.
