Updated to 6.0 It now supports the iPhone 5s screen. But does not seem to take full advantage of it for the camera. It seems like it should be able to show the full FOV for a 18mm Zeiss Superspeed on a Red One MX 4k 16:9 setup. But it still shows arrows on each side. It sometimes does not recognize button pushes. Making it extremely annoying to use the app. The screen goes black between menus. It seems like the thing has crashed. The whole app seems slower now.
