While the iPhone 5s’s 64-bit A7 processor has received the lion’s share of attention, 9to5Mac points out that we should take a look at the device’s M7 dedicated motion co-processor as well. As Apple describes it, the M7 is technology that “knows when you’re walking, running, or even driving” and can do things like automatically switch the type of directions it gives you when you stop driving and start walking.
9to5Mac’s sources say that Apple is planning to do a lot more with this, however, and is working to integrate it into iOS Maps so that it can mark your parked car’s location and help you find it in a crowded parking lot if you get lost. The M7 is also designed to take advantage of several new features Apple is planning for iOS Maps, including indoor mapping and public transit information, 9to5Mac’s sources say.
