Audio-Visual Entrainment combines binaural beats, isochronic tones, and rhythmic light to help balance brain activity. The light reaches you through your phone's camera flash or, in Headset Mode, its screen. Headphones are recommended for the strongest effect - they add a binaural beat layer on top of the tones - but because the isochronic tones work through any speaker, sessions still work without them. Sessions follow a carefully sequenced frequency journey with gradual transitions, not a single fixed tone. Developed in a practice office with a psychotherapist and a consulting psychiatrist, grounded in data from 1000+ sessions. WHO IT'S FOR: • People with depression seeking additional support tools • Those managing anxiety and panic attacks • Anyone struggling with insomnia or sleep issues • Professionals dealing with burnout • People wanting science-backed mental wellness support WHY 6TH MIND: Science-based approach to mental wellness. Whether you're dealing with depression, anxiety, burnout, or just need help relaxing and sleeping better, our methods are grounded in psychology and refined through 1000+ sessions in our practice office. Can be used alongside traditional therapy and medication. Download free today.
