Pages 10.0, Numbers 10.0, Keynote 10.0 (iOS)
iWork is an office suite of applications created by Apple Inc. for its macOS and iOS operating systems, and also available cross-platform through the iCloud website.
It includes Keynote, a presentation program; the word processing and desktop publishing application Pages; and the spreadsheet application Numbers.. Apple's design goals in creating iWork have been to allow Mac users to easily create attractive documents and spreadsheets, making use of macOS's extensive font library, integrated spelling checker, sophisticated graphics APIs and its AppleScript automation framework.
The equivalent Microsoft Office applications to Pages, Numbers, and Keynote are Word, Excel, and PowerPoint, respectively. Although Microsoft Office applications cannot open iWork documents, iWork applications can export documents from their native formats (.pages, .numbers, .key) to Microsoft Office formats (.docx, .xlsx, .pptx, etc.) as well as to PDF files.
The oldest application in iWork is Keynote, first released as a standalone application in 2003 for use by Steve Jobs in his presentations. Steve Jobs announced Keynote saying 'It's for when your presentation really matters'.
Pages was released with the first iWork bundle in 2005; Numbers was added in 2007 with the release of iWork '08. The next release, iWork '09, also included access to iWork.com, a beta service that allowed users to upload and share documents, now integrated into Apple's iCloud service. A version of iWork for iOS was released in 2010 with the first iPad, and the apps has been regularly updated since, including the addition of iPhone support. In 2013, Apple launched iWork web apps in iCloud; even years later, however, their functionality is somewhat limited compared to equivalents on the desktop.
iWork was initially sold as a suite for $79, then later at $19.99 per app on OS X and $9.99 per app on iOS. Apple announced in Late 2013 that all iOS and OS X devices purchased onwards, whether new or refurbished, are eligible for a free download of all three iWork apps. iWork for iCloud, which also incorporates a document hosting service, is free to all holders of an iCloud account. Then, in April, 2017, they released the suite, free for macOS and iOS.
In September 2016, Apple announced that the real-time collaboration feature will be available for all iWork apps.
