iPhoneScreenGrabber is a Mac OS X development tool to easily grab and save high-quality LZW-compressed TIFF, PNG, and JPEG screenshots from the iPhone SDK's iPhone Simulator. Although there are many techniques to grab screenshots from your iPhone/iPad, you can simplify your workflow by using iPhoneScreenGrabber to take perfectly cropped screenshots which are ready for upload to the iTunesConnect App Store backend. iPhoneScreenGrabber also includes a magical compositing feature to automatically format screenshots to match Apple's artwork guidelines, which includes the light mirrored reflection effect for landscape screenshot images.
