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. Medical Disclaimer: This app does not replace or provide medical advice and diagnosis. Always seek the advice of a physician or other qualified health provider with any questions you may have regarding a medical condition. Regulatory Jurisdiction: The SONU band is authorized for use by regulatory authorities only in the USA (FDA) and Singapore (HSA). Any feedback?
