Apple has announced the addition of an M7 co-processor at their live iPhone event today. The co-processor technology will assist in continuously measuring motion in a better and smarter way. This will open up the door to much better fitness and apps that deal with motion specifically.
The most interesting part of the M7 is what Apple will do with the technology. It's also something we would see pop up in a future iWatch, especially for use with fitness apps such as run and walk tracker apps. Nike is already working with the technology in their own fitness apps.
