I have been using various titles form the available collection. They are all high quality recordings that actually do work very well. I have several apps that use the NeuroSky brainwave feedback device and these apps from ZenZone are the best by far. They have a practical application that can help with your day to day lives. Checkout all the available titles and I’m sure you’ll find one that could help you as much as I have found them to be helpful. Highly recommend.
