Apple's office applications for Macs and iOS devices. Introduced in 2005 and superseding AppleWorks, iWork was intially sold as a suite of three apps for the Mac: Pages word processing, Numbers spreadsheet and Keynote presentation graphics. iWork was later unbundled, and the three applications were sold only as independent programs.
Although the native formats have .pages, .numbers and .key file extensions, popular formats such as Microsoft Word, Excel and PowerPoint can be imported and exported. See iLife
