It seems obvious in retrospect to consider that apps designed for iPhone 4 will nearly fill an iPad display. Conversely, iPad apps will nearly fit into the new phone’s Retina display without modification.
The stunning 960×640 resolution of the iPhone 4 Retina display is double the linear resolution of the current iPhone, giving it the highest pixel density of any smartphone on the market when it goes on sale later this month. The iPad’s 1024×768 resolution is just slightly larger despite having a much larger display surface. While the 132ppi pixel density of iPad was already the highest of any device Apple sells, the new iPhone 4 boasts a 326ppi resolution density.
The iOS app developer of Make Coffee depicts on its site how apps with a native resolution version designed for iPhone 4 will look on iPad (below); it’s the same as a pixel doubled version of a standard iPhone app, but in high resolution of course.
At WWDC, chief executive Steve Jobs noted during his keynote presentation that iPhone 4 will automatically scale existing iOS apps to its higher resolution, making text and user interface controls appear sharper without developers needing to do anything. Jobs noted that with a little additional effort, custom artwork can be enhanced to make iPhone 4 apps that look exceptional.
