M7

As well as being the very first smartphone on the market packing a 64-bit processor, Apple's iPhone 5s also features an M7 motion coprocessor, allowing processes to be more efficiently managed while also preserving those essential droplets of battery life. But while these new hardware upgrades are great and all, their powers can only be fully recognized once developers adapt their apps to take advantage of them, and Strava Run, the socially-swayed training app, is the first such utility to make use of the Cupertino's new coprocessor.
