Zoom an app to fill the screen on iPad

Most apps for iPhone and iPod touch can be used with iPad, but they might not take advantage of the large screen. In this case, tap the UI classic zoom expand button to zoom in on the app. Tap the UI classic zoom shrink button to return to the original size.

Check the App Store to see if there’s a version of the app that’s optimized for iPad, or a universal version that’s optimized for iPhone, iPod touch, and iPad.
