The DAVID SMART provides a unique fusion of audio-visual entrainment, also known as brainwave entrainment. The sessions have been thoroughly tested and are designed based on the most current research findings to ensure you the most effective results. The sessions on the SMART are designed to improve academic performance, reduce stress, boost mood, and improve concentration and memory in college students. The SMART sessions also include our proprietary randomization process, which helps encourage dissociation and brain frequency tracking to the stimulus. The SMART features five distinct categories of sessions: Energize, Meditate, Brain Brightener, Sleep and Mood Booster, with two selections for each category. The SMART also features night-vue ability, which allows the user to see the session select buttons in the dark at bedtime or at night.
