AppAdvice has once again teamed up with Banzai Labs in order to offer you a chance to win one of twenty (20) promo codes for Brain Wave for iPad, iPhone, and iPod touch ($1.99).

The time has come to celebrate a new year and make that “New Year’s Resolution.” Will it be to get to work on time every day, lose some weight, spend more time with family and friends, or maybe just to get a better night’s rest to be able to do the rest successfully?

No matter what your goals are, you’ll need to be in the right state of mind. To assist you in doing just that, check out Banzai Lab’s Brain Wave app containing 25 advanced binaural programs.

Brain Wave synchronizes your brainwaves to a specific frequency by sending two different audible frequencies to each ear, which after being processed are perceived as a low frequency tone matching human brainwaves. Studies have shown various states of mind to be associated with these low frequencies, ranging from an alert and focused state of mind to deep sleep.

Brain Wave recreates these frequencies using the most advanced binaural sequences available, allowing your mind you to relax and synchronize with your desired state. It achieves this using a unique process called Progressive Brainwave Entrainment.

The 25 binaural programs include: Morning Coffee, Espresso Shot, Morning Meditation, Focused and Alert, Critical Thinking, Concentration, Memory Boost, Problem Solving, Confidence Boost, Pre-Exercise Energy, Creativity Boost, Positive Mood Boost, Euphoria, Stress Reduction, Anger Relief, Calm Reflection, Reduce Anxiety, Deep Relaxation, Meditation, Lucid Dreaming, Sleep, Vivid Dreams, Power Nap, and Deep Sleep

Amongst the 25 programs, you’re able to choose one of seven ambient audio tracks to play in the background. Options include adjustment of duration for each program and each stage within that program, as well as the ability to adjust the volumes for each according to your preference. The buttons to the left of each section show or hide the detailed settings pain.

Directly below the program choice settings (gear icon) button is the button used to show and hide the highlighted program description, which will allow you to determine if that program is the choice appropriate for your goal and mood.

Brain Wave is designed for iPhone and iPod touch running iOS 3.1.2 or later, however, it does offer background multitasking features when used on an iPhone 3GS, iPhone 4, 2nd generation iPod touch and later running iOS 4.0 or later.
