App store

An app store, also called an app marketplace or app catalog, is a type of digital distribution platform for computer software called applications, often in a mobile context. Apps provide a specific set of functions which, by definition, do not include the running of the computer itself. Complex software designed for use on a personal computer, for example, may have a related app designed for use on a mobile device. Today apps are normally designed to run on a specific operating system—such as the contemporary iOS, macOS, Windows, Linux or Android—but in the past mobile carriers had their own portals for apps and related media content.[1]

This article is about the concept. For the store for most Android devices, see Google Play. For the store for Apple mobile apps, see App Store (Apple). For the store for Apple Mac apps, see Mac App Store. For the store for Fire OS, see Amazon Appstore.

Basic concept[edit]

An app store is any digital storefront intended to allow search and review of software titles or other media offered for sale electronically. Critically, the application storefront itself provides a secure, uniform experience that automates the electronic purchase, decryption and installation of software applications or other digital media.


App stores typically organize the apps they offer based on: the function(s) provided by the app (including games, multimedia or productivity), the device for which the app was designed, and the operating system on which the app will run.


App stores typically take the form of an online store, where users can browse through these different app categories, view information about each app (such as reviews or ratings), and acquire the app (including app purchase, if necessary – many apps are offered at no cost). The selected app is offered as an automatic download, after which the app installs. Some app stores may also include a system to automatically remove an installed program from devices under certain conditions, with the goal of protecting the user against malicious software.[2]


App stores typically provide a way for users to give reviews and ratings. Those reviews are useful for other users, for developers and for app store owners. Users can select the best apps based on ratings, developers get feedback on what features are praised or disliked, and finally, app store owners can detect bad apps and malicious developers by automatically analyzing the reviews with data mining techniques.


Many app stores are curated by their owners, requiring that submissions of prospective apps go through an approval process. These apps are inspected for compliance with certain guidelines (such as those for quality control and censorship), including the requirement that a commission be collected on each sale of a paid app. Some app stores provide feedback to developers: number of installations, issues in the field (latency, crash, etc.).

History[edit]

Precursors[edit]

Commercial Bulletin board services appeared in the early 1980s, such as Micronet 800 (1983), that permitted registered subscribers to browse, purchase, and download software for a variety of propriety operating systems, then offered by manufacturers such as Acorn, Apple, Commodore, Dragon, IBM, RML, Sinclair and Tandy. Some programs being included in the monthly subscription charge, the user only paying the per minute connection / data charges for a download, while other programs resulted in the user being additionally billed per purchase.[3][4]


The Electronic AppWrapper[5] was the first commercial electronic software distribution catalog to collectively manage encryption and provide digital rights for apps and digital media[6] (issue #3 was the app store originally demonstrated to Steve Jobs at NeXTWorld EXPO).[7] While a Senior Editor at NeXTWORLD Magazine, Simson Garfinkel, rated The Electronic AppWrapper 4 3/4 Cubes (out of 5), in his formal review. Paget's Electronic AppWrapper was named a finalist in the highly competitive InVision Multimedia '93 awards in January, 1993 and won the Best of Breed award for Content and Information at NeXTWORLD Expo in May, 1993.[8]
