I love the app and I have been using it for a few years now. I initially didnt think that it worked but, after research and then actually taking the time to read the directions on how the it all works within the application it turned out to be just what I need. I think the only thing I dont really like is that you cant go right into the level of the binaural mode that you need. They all start out on a relax mode and the binaural modes take sonic shape after the first phase is done.. There needs to be a way to go directly into the level of the program that you want to use.
