Apple this morning rolled out universal versions of all three of its iWork apps, bringing the suite to iPhone and iPod Touch devices.
Keynote, Pages, and Numbers (updated reviews), which have been on the App Store for the past year, were previously only available for iPad users. Today's updates shrink the same user interfaces down into pocket-size versions that let users create, save, open, and edit documents.
Along with going universal Apple has tweaked the user interface a bit to let users see thumbnail previews of documents to find them by sight.
The software suite originally made its debut on the Mac OS, beginning with Keynote, Apple's presentation software. Apple later added Pages then Numbers, rolling together all three applications into iWork. Apple now sells the individual applications through the Mac App Store, and in the iOS App Store, letting users get a single program without having to buy the others.
The apps continue to retail for $9.99 each, and this morning's update is free of charge to existing owners of the applications. The software is only available to users of Apple's more recent iOS products, including the iPhone 3GS and iPhone 4, third- and fourth-generation iPod Touch devices, and iPad and iPad 2.
