A '''web app''' is an [[application software|application]] that uses technologies such as [[JavaScript]], [[CSS|CSS3]], and [[HTML5]] and is executed in a [[web browser]].<ref name=gvoice>{{citation|url=http://www.informationweek.com/news/telecom/voice/showArticle.jhtml?articleID=222500168|title=Google Voice Storms Apple's iPhone |author=|date=26 January 2010|work=InformationWeek}}</ref> Developers release their applications as web apps because of the larger flexibility of the format.<ref>{{citation|url=http://www.zdnet.com/blog/apple/developers-defecting-from-app-store-to-html5/5547|title=Developers defecting from App Store to HTML5|author=|date=16 December 2009|work=ZDNet}}</ref> The application can be run directly from a website, or, if it uses the HTML 5 Offline Application Cache<ref>{{citation|url=http://developer.apple.com/safari/library/documentation/iPhone/Conceptual/SafariJSDatabaseGuide/OfflineApplicationCache/OfflineApplicationCache.html|title=HTML 5 Offline Application Cache|work=Safari Reference Library}}</ref> and [[Web Storage]], can be downloaded and installed locally, for offline use.

Web apps have been used to circumvent the restrictions Apple puts on [[iPhone]] applications sold through its [[App Store (iOS)|App Store]].
