Unbelievable useful
Hi everyone, Sometimes i hv some troubling sleeping schedule. Causing sleepy and dizzyness in the day after. But since i start using this application, i can monitorand track my sleep schedule. So i can manage my sleep and also the curve from this application is very useful. I positively can know when im in deep sleep in what time exactly and when im in light sleep term. It also can detect sleep talking. And what time exactly we start to sleep and how long our sleep. Very useful, i use it almost everyday. :)
