Can combined biofeedback and mental rehearsal enhance sport performance? This app is an attempt to articulate both this question and the potential responses while including conscious breathing, heart rate, body temperate (both biofeedback mechanisms), mental rehearsal and lucid dreaming, an extension of mental rehearsal but in an alpha and theta brain wave state. The athlete can use this app to track each of these 5 which overtime should help enhance both the training and then the competition and performance.
Hypnotic Ball

It's a hypnotic ball, it can move left and right up and down smoothly, it can move in a straight line or in a curve. You can even have two balls, one for each of your eyes.
