Before the Apple Watch I used a Jawbone Up 24. It tracked my steps and my sleep. Well the Apple Watch did not have that option so I stopped tracking my sleep. Well with WatchOS 2 a new app came on the market called Sleep++ that allowed you to track your sleep. It is not as robust as the Jawbone Up sleep tracking but I am sure that is some limitations of the WatchOS 2 and what the developer has access to.
Last night I got a decent amount of sleep. Since monitoring it looks like I hover around 9%-12% restless during the night. We will see what else the app developer has for this one. At this point it is a good start.
