By creating iPhone 6 and iOS 8 together, we optimized the software to enhance the physical design. iOS swipe gestures were designed to be more fluid across the seamless form, making it easy to navigate iPhone with one hand. With new features like Reachability you can interact with the larger screen in different ways, too. Simply double touch the Home button and the entire screen shifts down closer to your thumb. And to easily navigate Safari or Mail, swipe left to right across the screen to go backward, or swipe right to left to go forward. With the new continuous surface of iPhone, all your gestures now feel smoother than ever.
