The COAST app will allow you to report daily on your sleep and health habits daily, communicate with your sleep healthcare provider as needed, report your symptoms and progress, and receive personalized instructions from your provider. All recommendations you can receive via the COAST app from your provider are based on scientifically proven techniques that improve sleep quality through behavior change. Your COAST app will adapt according to your provider’s decisions regarding your sleep care, including the appropriate duration of the program for you. Most people complete their provider-supervised program in 6 weeks.

Elemind is pioneering neurotechnology for sleep that reads and instantly responds to your individual brainwaves and works naturally to direct your brain out of wakeful patterns into a deeper sleep, on-demand. Our patented algorithm tracks your EEG brain signals and delivers precise acoustic stimulation tailored to your brain’s natural rhythms - so you fall asleep significantly faster. Like noise cancellation for the brain, you can switch off the world and switch off the stress and go to sleep faster because with Elemind you actively drive your brain from an awake state to a sleep state. Elemind is clinically shown to improve sleep efficiency. It is designed to help you fall asleep as fast as the leading sleep drugs, without the negative side effects or next day grogginess. Which means that when you wake up, you’ll feel at your best and ready for whatever the day brings. The Elemind app is designed to pair with our EEG-based headband, which houses multiple sensors designed to accurately track your sleep. However, different from other sleep trackers, the Elemind headband analyzes your brain activity in real time to deliver precisely timed acoustic stimulation via a bone conduction speaker that has clinically been shown to get you to sleep faster. The app features: DETAILED SLEEP MONITORING Sleep isn’t a score to chase—it’s a rhythm to understand. Elemind skips oversimplified metrics and delivers data-driven insights that support healthier, more natural sleep—so you can wake up feeling truly restored. The Elemind app provides raw and derived metrics in clear visual formats like hypnograms and bar charts, paired with context that helps you interpret them. You’ll see how long you were in each sleep stage, how efficiently you slept, and how your sleep changes over time—all without being reduced to a grade.
