Works great. Ive learned so much about my sleep and this feedback has helped me improve my sleep and overall health. Before this App I actually fell sound asleep at a meeting at work ..... The App may have saved my job.
Last of all Im buying my wife an Apple Pro. Apple sells a hardware accessory to track sleep for about $150. And its specs say it does, get this, approximately the same thing this App does. I know this App works great! I dont know about Apples accessory hardware add on!
Try this, youll like it and learn a lot about your sleep!
