A Chance To Win A Brain Wave Promo Code For iPad, iPhone And iPod Touch

AppAdvice has once again teamed up with Banzai Labs in order to offer you a chance to win one of 24 promo codes for Brain Wave ($1.99) for iPad, iPhone, and iPod touch. Using the concept of brainwave entrainment in combination with ambient sounds, Banzai Labs' Brain Wave is able to gently and subtly influence a specific state of mind. The app provides 11 ambient sounds and 30 different programs that contain multiple sequences focused on different brainwave stimulation. Here are just some of the included programs:

• Critical Thinking
• Concentration
• Memory Boost
• Problem Solving
• Brainstorm
• Confidence Boost
• Euphoria
• Meditation
• Lucid Dreaming
• Headache Relief

  What is brainwave entrainment? It's the process of using audible or visual stimuli to change a person's brainwaves, which are related to certain actions and capabilities, through the means of synchronization.

• Delta waves are less than or equal to four hertz, and associated with deep sleep.
• Theta waves are between four and seven hertz, and associated with drowsiness.
• Alpha waves are between eight and 13 hertz, and associated with relaxation.
• Beta waves are between 13 and 30 hertz, and associated with high alertness and focus.
• Gamma waves are between 30 and 70 hertz, and associated with problem solving.

  Because most of the frequencies are subsonic, below the 20 Hz limit of the human ear, entrainment must be done via binaural beats, a trick of using stereo sound through standard earphones or headphones to create the perception of a very low frequency. For example, Brain Wave could input a 270 Hz beat into the left ear and a 281 Hz beat into the right to create the perception of an Alpha wave, i.e., a frequency difference of 11 Hz. Now that the methodology is out of the way, it's time to get a glimpse of what Altered States is made of. Whether using the app on iPad or iPhone, the user interface places dominance on program selection, but also has volume, playback, sound, and duration controls within easy access. Somewhat tucked away are adjustments to fade durations and an alarm. One of the significant differences for iPhone users is the lack of showing the program description onscreen continuously, instead requiring the user to tap on the info "i" button.
