I have to sleep with a bipap breathing machine. I put on a set of headphones and turn on the sleep deeply digipill and it knocks me right out and I sleep very well. If you know someone that has a mask forcing air in their lungs at night making noise and making it hard for them to fall to sleep. This app is the hot ticket.
