One might think that this software is just a placebo effect but no, he really studied our sleep and we transcribed a rather basic graphic detail, the software is based on the fact that doing this has awaken a fixed time when we are may be in a deep sleep that moment can be bad on your qualiter up and affect the rest of your day and indeed!
After having made any adjustments can a difficult I must say, the program not only awakens us when we are in light sleep, but also smooth thanks to the little bird chirping rather than a big BEEP BEEP wake of a classic that you wake up with a start, if you set your insis a 9am wake up with a 20 minute interval wakes up, it will study the best time or wake up between 8:40 ET 9:00, and even if you feel lost 20 15 or 10 minutes of sleep I can make sure this is beneficial in the end because you wake up and almost burst least able from live to work!
also this one also offers other option, like sounds (lullabies call) to help you fall asleep, the sound of water, rain, or resonance, in a cave and that sound can be play during wished to last 30 minutes and will drop for example in volume for 10 minutes, for example sarrêter up completely and, yes, ca seems silly, but it really helps is great
And some other options I'm not going to quote you, but for example, record the sounds you made the night (snore or talk) graphics on your light / deep sleep etc. .
On a galaxy note 3 it pumps me around 15% battery on a night 8am, reasonable!
Overall I give him 18/20 because it is a bit complex set early
