COMMAND YOUR STATE. The Domayn app runs the Domayn Mask, the audio‑visual neuromodulation device that uses precision‑engineered light and sound to guide your nervous system toward the state you choose. Wake. Focus. Relax. Sleep. Requires the Domayn Mask. Pair over Bluetooth, choose a protocol, press start. In five to fifteen minutes, precision light and sound guide you toward the state you need. Non‑invasive, no drugs, no prescription. Many people feel the difference in their first session. Interior. Under control. FOUR PROTOCOLS • Wake, a clean, clear start to the morning • Focus, calm, sustained concentration for the work that matters • Relax, come down after a demanding day, or before a high‑pressure moment • Sleep, guide yourself toward deep rest New to it? Start with the Welcome session to learn the ropes. IN THE APP • Library, every guided protocol in one place, from a five‑minute midday reset to a fifteen‑minute wind‑down • Sessions, a simple log of your sessions, total time and streaks • Recommendations, a suggested protocol for the time of day • Wearables, connect Apple Health, Oura or WHOOP and view your data alongside your session log • Guest mode, hand your phone to a friend and let them try the Mask. Their sessions log separately, so your streak stays yours EARLY ACCESS The Mask is in limited early access, by invitation. You are getting an early version of the experience and helping shape what it becomes. New protocols and features arrive over time. GROUNDED IN SCIENCE Audio‑visual stimulation is a non‑invasive, non‑pharmacological form of neuromodulation, grounded in decades of neuroscience research. Rhythmic light and sound, delivered at a steady frequency, can guide brain activity toward similar frequency ranges. That process is called neural entrainment. Each protocol is a structured sequence of light and sound, engineered to guide you toward the state you chose. SAFETY The Mask uses light and sound. Do not use it if you have photosensitive epilepsy or a history of light‑triggered seizures. Stop use and consult a doctor if you feel any discomfort. If you have a medical condition, are pregnant, or take medication, consult your healthcare provider before use. The Domayn Mask is a consumer wellness device, not a medical device, and is not intended to diagnose, treat, cure or prevent any disease.
