Here’s Apple’s iPhone Duo design guidance for app developers.
It’s an interesting video that gives you a better idea of how apps might look on the device. I really like all the different ways apps can appear based on the “pose” of the Duo, and I hope a lot of developers do the right things to make that all work. Apps that aren’t updated for iOS 27 SDK might look a little wonky, though. [Media: https://www.youtube.com/watch?v=do3UqxfYc3I]
