iPhone and iPod touch owners can now download and install Keynote, Pages and Numbers apps on their devices.
There has been an iPad version of the three iWork apps since the launch of the original iPad but until now iPhone and iPod touch owners weren't able to use the productivity apps.
The three new iWork apps are available on the App Store for £5.99 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," said Philip 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, organise and share all of your documents from iPhone 4 or iPod touch."
With the three apps you can import and export documents from iWork for Mac and Microsoft Office and print wirelessly using AirPrint.
An additional Keynote Remote app can be purchased for 59p and allows your iPhone or iPod touch to control a Keynote presentation on any iOS device or Mac.
