When it comes to wearables, and fitness trackers in particular, they are yet to fully realise what they do best in our opinion. Fitbit for example, has a mix of fitness tracking features, as well as ones that work while users are sleeping. It's the latter which the company has been paying more attention to of late, unveiling a range of new features built around a system it calls Sleep Schedule. 

The system works via the Fitbit app in conjunction with a compatible wearable device from the American manufacturer. As such, users can craft specific goals around sleep data the Fitbit device has recorded from previous nights, giving users the ability to set wakeup times and goals around specific hours of sleep. 

The Sleep Schedule array of features are still in their infancy, with Fitbit reportedly working with doctors and users alike to maximise the potential that sleep tracking holds. To that end, sometime down the line, Fitbit aims to use their wearables to help users to not simply sleep longer, but have a better night's rest. 

As for whether consumers will hanker for such features, remains to be seen.
