The iPhone 5s is the first iOS device to include the new M7 motion co-processor. The chip gathers motion data from the accelerometer, gyroscope, and compass and translates that information into body motion. There are a small, but growing number of fitness apps that use the M7 to track your daily steps. Here are a handful of apps that'll give you peek into the type of information that is being monitored by the M7.
MotionX-24/7 is an activity tracker and sleep monitor for the iPhone. It allows you yo analyze your sleep cycle, monitor your workouts and track your weight. A smart alarm feature will track your sleep cycle and wake you up at the optimal time.
