Apple has unveiled a new processor for its iPhone 5S that will attempt to improve its handset's interaction with health and fitness apps.

Unveiled on Tuesday by Apple's Phill Schiller, the M7 is what the company calls a "motion coprocessor." The coprocessor continuously measures motion data through the accelerometer, compass, and gyroscope, taking it away from Apple's standard A7 processor.

According to Schiller, the coprocessor will determine if a person is stationary, walking, or driving, and can be incorporated into health and fitness apps to analyze movement. Schiller also unveiled a new app, called Nike+ Move, that utilizes the coprocessor.

Other than that, Apple has remained tight-lipped so far on exactly what the iPhone 5S' coprocessor might be used for. It's possible, Schiller says, more fitness and health apps will use it in the coming months.

Details about Apple's 'spaceship' campus from the drone pilot who flies over it

MyithZ has one of the most popular aerial photography channels on YouTube. With the exception of revealing his identity, he is an open book as he shares with CNET's Brian Tong the drone hardware he uses to capture flyover shots of the construction of Apple's new campus, which looks remarkably like an alien craft.
