Sleep Tracking features will apparently roll out to the Apple Watch by 2020 The Apple Watch is tipped to get built-in sleep tracking features with the Cupertino company said to be in the process of testing out the feature before it rolls it out to its smartwatch. That's according to a report by Bloomberg, which claims sleep-tracking has been tested at secret sites at its various headquarters. Should all the testing go to plan and it works without issues, it will apparently roll out to the Apple Watch by 2020
