After the success of Apple's App Store, and the launch of similar services by its competitors, the term "app store" has been adopted to refer to any similar service for mobile devices. However, Apple applied for a trademark on the term App Store in 2008

In February 2011, Apple announced its new subscription based service which will allow publishers to set the length and price of a subscription. Previously, new magazine or news releases would be sold on a per release basis. The new service allows publishers to sell their content through their apps allowing users to receive the new content over specified period of time. More interesting is that Apple will allow publishers not only to sell from iTunes where revenue will be shared (70% for the publisher, 30% for Apple), but they are also allowing publishers to distribute their subscriptions directly from their websites where no revenue will be shared with Apple.

This major Roadmap event (coupled with a large distribution program for 3rd-party developers), later became known as the iPhone Developer Program, which currently offers two distribution tracks for 3rd-party developers: Standard, and Enterprise.

Applications distributed through the standard program can be sold exclusively through the iTunes Store

 on Mac and Windows, or on the App Store on the iPhone, iPod Touch, and iPad. Developers who publish their applications on the App Store will receive 70% of sales revenue, and will not have to pay any distribution costs for the application. However, an annual fee is required to use the iPhone SDK and upload applications to the store.

Applications developed through the enterprise program, officially the "iOS Enterprise Developer Program" (iDEP), are exclusively for institutional use and do not get published on the App Store. This allows corporations, non-profits and government agencies to develop proprietary "in-house" applications not for public release. The enterprise program was updated September 14, 2010, to allow any organization with a DUNS number

Unlike the apps that come standard on the iPhone, apps downloaded from the App Store can be removed by the user at a future date.

Revenue Share

Besides downloading volumes, the App Store's relatively high revenue of US$1782 million in 2010 may be attributed to it having only 28% of free apps, in comparison to Android Market

iPad Applications

The iPad launched in April 2010 with over 3000 applications designed for the iPad. By December 2010, just eight months after the release of the iPad, over 50,000 apps were available for the device.

As of July 2011, 16 months after the iPad launched, there are over 100,000 apps available at the App Store designed specifically for the device.

On the July 7, 2011, Apple announced that over 15 billion apps had been downloaded from the iOS app store. But, micro level information on the number of downloads of each ranked application has not been made available. To help app producers with their marketing effort and help researchers in better understanding the Apple's iOS app store, a recent research study has tried to estimate the model that converts the app rank to daily downloads. Researchers Garg and Telang from Carnegie Mellon University
Carnegie Mellon University
Carnegie Mellon University is a private research university in Pittsburgh, Pennsylvania, United States....

 found that the app downloads follow a Pareto distribution and can be estimated using the equations:


iPad_app_downloads = 9,525 * paid_app_rank^(-0.903)


iPhone_app_downloads = 52,511 * paid_app_rank^(-0.944)



NOTE: this claim has not been verified by Apple or any other market research organization.

Application ratings

Apple rates applications worldwide based on their content, and determines what age group each is appropriate for. According to the iPhone OS 3.0

 launch event, the iPhone will allow blocking of objectionable apps in the iPhone's settings. The following are the ratings that Apple has detailed:
Rating Description
4+ Contains no objectionable material.
9+ May contain mild or infrequent occurrences of cartoon, fantasy or realistic violence, and infrequent or mild mature, suggestive, or horror-themed content which may not be suitable for children under the age of 9.
12+ May also contain infrequent mild language, frequent or intense cartoon, fantasy or realistic violence, and mild or infrequent mature or suggestive themes, and simulated gambling which may not be suitable for children under the age of 12.
17+ May also contain frequent and intense mature, horror, and suggestive themes; plus strong sexual content, nudity, strong language, alcohol, tobacco, and drugs which may not be suitable for children under the age of 17. Also, if the app accesses the internet it is rated 17+. Consumers must be at least 17 years old to purchase apps with this rating. Whenever an app of this rating is requested for download, a message will appear, verifying if a user is 17 or older, and asking to confirm the purchase for this reason.

App approval process

Applications are subject to approval by Apple, as outlined in the SDK agreement, for basic reliability testing and other analysis. Applications may still be distributed "ad-hoc" if they are rejected, by the author manually submitting a request to Apple to license the application to individual iPhones, although Apple may withdraw the ability for authors to do this at a later date.

s (NDA) have always forbidden developers from publishing the content of their rejection notices, but Apple has now started labeling their rejection letters with Non-Disclosure (NDA) warning THE INFORMATION CONTAINED IN THIS MESSAGE IS UNDER NON-DISCLOSURE. Apple later changed the NDA citing that "it has created too much of a burden on developers" but they did not reverse the decision to forbid publication of rejection notices. Some applications are not available outside the US App Store at the request of the developer. Since so many developers have published rejection emails Apple now most often call submitters to verbally tell them their rejection notice.

In addition, Apple has removed software licensed under the GNU General Public License

Enterprise App Stores

Because Apple's App Store is for consumers, companies are unable to distribute in-house apps on the App Store. Under Apple's iOS Developer Enterprise Program companies can publish in-house apps using an Enterprise App Store with systems such as Apperian

 EASE or a Mobile Device Management platform such as Sybase Afaria.

Apps published with Apple's iOS Developer Enterprise Program are still subject to Apple's control via the controversial kill switch, where Apple can revoke a publisher's digital certificate and thereby "kill" the app on user devices. However, there is no evidence that this has been done in the enterprise environment.
