The iPhone 6S might look almost identical to the iPhone 6 (it’s a tad thicker and comes in some new colors), but thanks to 3D Touch, which is the same idea as Apple Watch’s Force Touch, the new Apple smartphone will offer a deeper level of interactivity. Instead of tapping an app to open it, now you can lightly press the screen to “peek” at it or press harder to make it “pop.” For example, when you press harder on the Phone icon, it takes you straight to voicemail. The goal here is less jumping through menu options to perform the tasks you’re looking to accomplish. After a little learning curve, we’d imagine it will be very useful. As for what else is new, well the cameras both got some impressive updates—the back can even capture 4K video—and the 6S will come packed with a new A9 processor for faster speeds. Pre-orders start September 12, and the new phones will run iOS 9.
