It's ok but the fact that it doesn't understand the difference between sleeping and reading or watching TV spoils it for me. The smart bed aspect was a huge selling point and after a week or so, I mostly gave up on it. If the app can't detect my intentions, I'd be happy to tell it that I'm going to bed or that I'm awake. I don't like that even if I edit the sleep time, it takes the unedited period of time for my stats. As a result, I don't feel like I'm getting a "smart"experience that I trust.
