Apple says the system might help you get better sleep by helping you manage when you should head to bed at night and wake up in the morning.
Crowds wait in anticipation for the release of the iPhone 6 at Apple Store on September 19, 2014 in Sydney, Australia. Australian buyers get first dibs because of the local time zone, which is several hours ahead of the US and other parts of the world.
Apple says they're exploring ways to use the iPhone to help users sleep.
The company is testing a new system that would automatically control alarms and notifications to manage when to head to bed at night and wake up in the morning.
The sleep tracker would use sensors to track the gap of time between when someone goes to bed and the actual moment when they fall asleep.
An alarm would be set unless an item in the user's calendar takes precedence.
