Very Handy Tool!
If you want to know what is going on while you sleep, this is the app for it! It records in great detail your sleep rhythm from the time you program it, until the time you wake up. I have been using this app for quite sometime. It is easy to use and simple to manage. Is fun listening to your sleep and is also a way of self discovering your night activity.
