Good but not so good – Sleep Better: Sleep Cycle App Review

I've had issues with this app, I figured that it would wake me in light sleep and I would feel refreshed like others do but I don't. It seems to be at random when I'm woken up. I love the ease of use and being able to track what levels of sleep I am in but I wanted that I'm all better feeling, and I just haven't gotten it. Is there any way to improve the sensing on the app so that it adjusts to when the BEST moment is?
