You may have seen augmented reality navigation before, but the arrival of AR-native frameworks is making it considerable slicker and more accessible. Case in point: Blippar. Its just-launched AR City app for iOS uses Apple's ARKit to clearly outline where you have to walk, and highlights nearby points of interest based on what you can actually see. And more importantly, it promises to be more accurate than GPS alone. The app uses visual inertial odometry (that is, interpreting movement seen through the camera) to minimize distance errors and prevent you from turning on to a side street by mistake.
