I got this app couple of months before having knee replacement surgery this past summer. I already have a chronic illness and havent slept well for years and was quite apprehensive of the surgery. This app worked very well on my insomnia and anxiety before surgery and really helped with pain after the surgery and during physical therapy (which is no picnic). I would recommend this for anyone who needs help with insomnia, anxiety, pain or just to relax and wind down after a hard day. You really need headphones/earbuds for it to work in my experience. My earbuds got misplaced for 24 hours while in rehab facility after knee surgery and it didnt work at all without them. It is worth every penny paid many times over (note to Devs-but please dont raise the price, it is a Godsend to those of us on fixed incomes)
