Wow its Magic!
This is an interesting application. It consists of several recordings of a British man talking to you. By listening to him you gradually grow wearier and wearier, more tired and more tired... until you in a very relaxed state. This application is great if you want to fall asleep. Also amazingly enough its free! I recommend downloading it if you want to sleep or if you want to hypnotize your sister to sleep!
