Apple says its iWork productivity apps — Keynote, Pages and Numbers — are now available for the iPhone and iPod touch, as well as iPad.

Created for the Mac and then completely redesigned for iOS and Apple’s Multi-Touch interface, Keynote, Pages and Numbers allow you to create and share presentations, formatted documents and spreadsheets on the go. iWork apps are available on the Apple App Store for US$9.99 each to new users and as a free update for existing iWork for iPad customers.

“Now you can use Keynote, Pages and Numbers on iPhone and iPod touch to create amazing presentations, documents and spreadsheets right in the palm of your hand,” says Phil Schiller, Apple’s senior vice president of Worldwide Product Marketing. “The incredible Retina display, revolutionary Multi-Touch interface and our powerful software make it easy to create, edit, organize and share all of your documents from iPhone 4 or iPod touch.”

Keynote, Pages and Numbers import and export documents from iWork for Mac and Microsoft Office; print wirelessly using AirPrint; and Apple-designed themes and templates. All iWork apps now include improved document management with thumbnail images that let you find your files quickly, organize them and group them into folders using intuitive gestures, says Schiller. From the Tools button in the toolbar, you can share any presentation, document or spreadsheet without leaving the app.
