SONU provides personalized, drug free, acoustic resonance therapy to treat nasal congestion symptoms caused by allergic and non-allergic rhinitis. SONU is backed by FDA authorization, extensive clinical trials, and enhanced by AI. SONU works with iPhone X or later models and uses Bluetooth to connect with your iPhone. To get started simply download the app and follow the on-screen instructions to get to your 15 minute treatment session. You can choose to relax with the gentle micro vibrations or go about your daily activities. The SONU app takes a scan of your face using the front facing camera and personalizes the acoustic therapy based on your facial anatomy and other proprietary factors. The acoustic resonance is delivered via medical grade bone conduction transducers in the SONU band (a lightweight, wearable headband purchased separately). SONU is proven to be safe and effective and also has a history of your treatment sessions in the app so you can track your usage over time.

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.
