The appearance of the calculator application included in Apple's iOS 3 mimics the appearance of the 1987 Braun ET 66 calculator designed by Rams and Dietrich Lubs, and the appearance of the now playing screen in Apple's own Podcast app used to mimic the appearance of the Braun TG 60 reel-to-reel tape recorder, before a later redesign of the app removed it. The iOS 7 world clock app closely mirrors Braun's clock (and watch) design down to the font and layout used. In Gary Hustwit's 2009 documentary film Objectified, Rams states that Apple Inc. is one of the few companies designing products according to his principles.
