iPad updates for existing applications have begun to appear in the App Store. Rather than releasing separate iPad versions of their apps, some developers have chosen to release “Universal” updates to the existing apps, providing both iPhone and iPad support in the same application package. Universal apps are denoted on the App Store by a small Plus sign beside the purchase button in the app listings, similar to the icon that was formerly used to denote iTunes Plus music tracks.
A note also appears on the App Store page for Universal apps indicating that “This app is designed for both iPhone and iPad” and Universal apps will appear in search results under both the general Apps and the new “iPad Apps” headings. The App Store page for Universal apps now includes a selection button above the screenshots where users to choose to view either iPhone or iPad screenshots for the app.
Despite the packaging of content for both platforms into a single app, most of the Universal app updates do not show a significant increase in size over their previous versions. As with all previous iPhone OS app updates each of these are available free to existing users, and new users gain the benefit of paying one price for a single app that will run on the iPhone, iPod touch and iPad.
As with iPad apps, Universal Apps are grouped into their own category in the Apps grid view in iTunes.
