Do you need to show off your app on two devices? Or even maybe both your website and your app? If your answer is yes then this is the perfect stage for you. On one side you have an iPad in landscape modes and on it’s bottom right you get an iPhone in portrait view. The backdrop is a simple white, signature of apple products. The devices give a slight drop shadow and reflection on the white surface. This gives the perfect side by side comparison for an any app or website mockup.
