App Store (Apple) in the context of "IPad"

Application software is software that is intended for end-user use – not operating, administering or programming a computer. An application (app, application program, software application) is any program that can be categorized as application software. Application is a subjective classification that is often used to differentiate from system and utility software.

The abbreviation app became popular with the 2008 introduction of the iOS App Store, to refer to applications for mobile devices such as smartphones and tablets. Later, with the release of the Mac App Store in 2010 and the Windows Store in 2011, it began to be used to refer to end-user software in general, regardless of platform.

iTunes is a media player, media library, and mobile device management (MDM) utility developed by Apple. It is used to purchase, play, download and organize digital multimedia on personal computers running the Windows (and formerly macOS) operating systems, and can be used to rip songs from CDs as well as to play content from dynamic playlists. It includes options for sound optimization and wireless sharing.

iTunes was announced by Apple CEO Steve Jobs on January 9, 2001. Its original and main focus was music, with a library offering organization and storage of Mac users' music collections. With the 2003 addition of the iTunes Store for purchasing and downloading digital music, and a Windows version of the program, it became an ubiquitous tool for managing music and configuring other features on Apple's line of iPod media players, which extended to the iPhone and iPad upon their introduction. From 2005 on, Apple expanded its core music features with support for digital video, podcasts, e-books, and mobile apps purchased from the iOS App Store. The release of iOS 5 in 2011 made these devices less dependent on iTunes, though it could still be used to back up their contents.

DeepSeek is a generative artificial intelligence chatbot by the Chinese company DeepSeek. Released on 20 January 2025, DeepSeek-R1 surpassed ChatGPT as the most downloaded freeware app on the iOS App Store in the United States by 27 January. DeepSeek's success against larger and more established rivals has been described as "upending AI" and initiating "a global AI space race". DeepSeek's compliance with Chinese government censorship policies and its data collection practices have also raised concerns over privacy and information control in the model, prompting regulatory scrutiny in multiple countries. However, it has also been praised for its open weights and infrastructure code, energy efficiency and contributions to open-source artificial intelligence.

iTunes Store is a digital marketplace selling songs, albums, music videos, ringtones and alert tones. It was launched by Apple Inc. on April 28, 2003, for Mac OS X, and on October 16, 2003, for Microsoft Windows. It launched as a mobile application with iOS on June 29, 2007.

It previously sold mobile applications until the launch of the App Store on July 10, 2008, and e-books until the launch of the iBooks Store on March 31, 2010. It also used to facilitate the downloading of podcasts which later became integrated into Apple Podcasts, as well as the provision to buy and rent films and TV shows which has since become integrated into Apple TV.
