The Macbooks webcam is a lot lower in quality when compared to even older iPhones, so the image quality would be really low. Also, Macbooks do not have a Neural Engine at the moment, so running advanced machine learning algorithms in real-time is not really an option, when compared with the low quality webcam. The iPhones & iPads, though, have both a Neural Engine and a very high quality camera, and we're making full use of them with our solution.
