The first app to take advantage of Apple's new M7 motion coprocessor has been released, and it's Strava Run. The app, like many other fitness running apps, allows you to track your distance, speed and numerous other variables of your run. What makes it unique for now, however, is the fact that it pulls data from the M7 in addition to GPS. From its version 3.5.3 release notes:
We've taken advantage of the M7 coprocessor in the iPhone 5S to make some big improvements for runners:
• Auto-pause: Get better accuracy in your pace and feedback. Your run will now automatically be paused when you stop moving.
• Run longer: Reduced battery consumption means you can spend more time on the roads and trails.
Updated for iOS 7.
The M7 chip is a companion chip to the A7 found in the iPhone 5s. It allows much of the motion data work from the accelerometer, gyroscope and compass to be offloaded from the A7 to the M7, resulting in better battery performance. It's also much better adapted to measuring types of movement, such as whether you are walking, running, on a bicycle or in a car.
Strava Run is a free download.
