iOS Developer Mario Baluci of The App Machine has released some screenshots of his Make Coffee application for the iPhone 4, illustrating how the higher-resolution version will scale and render on an iPad device. Baluci notes in the company’s blog that the iPhone 4 native resolution application looked “terrific” on the iPad and actually runs at an almost full-screen resolution. The resolution of the iPhone 4 is 640 x 960 as compared to the 320 x 480 display used on prior iPhone models. By contrast, the iPad uses a 768 x 1024 resolution screen. Make Coffee is a virtual coffee machine novelty application for iOS devices. Version 2.0 will provide higher-resolution graphics for the iPhone 4, more advanced 3D animations and sound effects and Twitter integration.
