App Store and Mac App Store are convenient ways to distribute programs and games. They allow developers to sell their applications without thinking about signing contracts, accounts, downloads, and so on.. In return, Apple picks up 30% of software sales.

But the company's services have one significant drawback: developers can not offer users of their applications new versions at a discount. The App Store does not provide discounts on updates.

Flexible pricing policy is of great importance for the distribution of software, it allows you to hold users, rewarding them for their loyalty. Updates often bring minor improvements and a few extra features, so it's unfair to expect current users to pay the full price.

In a recent interview, Phil Schiller, senior vice president of marketing for Apple, evaded the issue of discounts on updates for users. He said that to realize this possibility is much more difficult than it might seem at first glance. In addition, according to him, this option is not needed by most developers, since many prefer a subscription model.

Usually, Apple does not abandon the implementation of new opportunities under the pretext of the complexity of implementation. In addition, a similar feature is already in the iTunes Store.

If you have already purchased individual songs from an album or series from a TV show, then they are deducted from the cost of a full album or series upon purchase.

Users simply are not profitable to make an expensive subscription to the application, which is updated every few years. Developers who do not want to follow this model are in a worse situation, since new versions of applications should be sold for the full cost. Most likely, it's not that Apple can not enter discounts on downloading updates for users. She just does not want this.
