Hi, trying to get to use my AW at night since charging is not an issue really. I tried Sleep Motion 2 but the sync procedure is nothing short of unreliable in my experience. What are other people using? Is there actually an app that would wake you during 'light' sleep so you're not as exhausted? Does this actually help or just marketing? I'm actually quite surprised that Apple thinks it's important to stand once per hour but doesn't care about 1/3 of the day and is not offering an in-house solution.
