I found an app called Psychic Beats a few days ago and wanted to share it with all of you. What it does is it allows you to basically make your own binaural beats. It has 5 settings (Enhance, Intuition Lucid, MindEx, and Shaman), 7 backgrounds (Brown, Pink, White, Forest, Rain, and Waves), and a timer. This app costs 3 US dollars but its only available on the IOS App Store.
