Good concept. Flawed execution.

There are two glaring problems with this app. The first is that when it shifts between brainwave states, there is a loud switching sound. So even if it is working to put you to sleep, as it attempts to take you deeper it actually jolts you awake. The second issue is the inability to control the brainwave and sound effects volume individually. The first issue is the main problem. If that can be fixed so the transition between frequencies is seamless, I will update my rating.
