Apple is reportedly working on a sleep tracker for the Apple Watch

During the unveiling of the new Apple Watch, the iPhone-maker presented the wearable as primarily a fitness device. And although there are still several fitness functionalities the Apple Watch is missing, it's no surprise that the company is looking to fill in some of the blanks. According to a report from Bloomberg, Apple is working on a number of new apps for its wearable, including one tracking users' sleep and another interpreting their general fitness based on heartbeat data.
