An activity monitor for your brain that teaches you about cognitive performance. 

Turn the invisible activity of your mind visible! Melon's brainwave monitoring headband listens to the electrical activity naturally given off by your brain. Using Bluetooth 4.0LE, Melon connects to your phone to help you track and train several mental states, including focus, meditation, and relaxation. The mobile app lets you understand how your behavior affects how you feel and teaches you how to improve. The headband is adjustable in the back to fit all head sizes for people ages 10 and up.
