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?

But whoever at Sonu vibe-coded this app clearly skipped massive details. Things that were easily accessible in the previous app are now entirely gone. Core functionality also got buried. I can’t see basic things like battery life; there’s 0 warning about audio being too high; and the alignment check from pre test (to make sure you have it placed well) has been replaced with a manual voice-breath test. Pretty sure that test does nothing anyway. Give me back all of the of the old features, I do not care about my streaks or tracking metrics. **Developer response:** Update - Please update the app to the latest for the audio level indicator. Other improvements are slated for the next update. Thank you for the feedback. The alignment check is available under Account -> My SONU Band -> Band Fit Guide. This guide will show up before treatment as long as you have not opted to skip it permanently. The SONUCheck voice analysis is optional and can be skipped each time (Skip to treatment on top right of the screen) or permanently from the Account preferences section. ### 2/5 — I liked the old version of the app better *2026-08-15, version 2.0* This new version of the app is so much more trouble than the old version. I keep needing to put in a username and password then go back into my iOS setting to reconnect the band. I am spending far too much time messing around with this thing just trying to get it to work. The old app just worked flawlessly every time. ### 2/5 — Loved before the update *2026-08-14* Loved before the app update, now it makes it difficult to use. Im unsure why the developers would change the app completely it worked perfectly fine before, now I cant use it on my iPad, I have to sign in every time, it’s more complicated to use, please change it it’s not user friendly at all I was a big fan before **Developer response:** Hello, Thank you for the feedback. We've identified the issue with staying permanently logged in and have fixed this in the latest app update so you don't need to keep signing in. We are also working to improve the iPad layout and experience. ### 5/5 — Love the new SONU 2.0 version *2026-08-14, version 2.0* I love how the new SONU app is designed. It’s too smooth and simple to use. ### 3/5 — Updated App - not so good *2026-08-10* I have used Sonu for over a year and love it - 5 stars for Sonu headband! But I'm not happy with the latest app! I have to log in every time I open the app, before it just opened to me. The app no longer gives me real data for pressure and Air quality conditions. I'm sorry, bar graphs are worthless without real number scales, not words. I used the data to track other health issues - like migraines and it was very helpful when I was discussing it with the doctor. **Developer response:** Hello, We love that you love the SONU Band! Please update the app to the latest version as the login issue has been fixed. The pollen and air quality metrics will be available in the next update. Thank you again for the feedback. ### 1/5 — Bugs in new version! *2026-08-09, version 2.0* The app will not let me proceed after entering my email. It tells me to verify my email before resetting my password, and basically puts me in an infinite loop. It used to be so good. ### 5/5 — Phenomenal *2026-07-09, version 1.4.3* First day felt it!! I could feel mucus breaking up, and I’m capable of breathing better. The stuffiness did return but nowhere near what it was. I’m pretty confident with continued use this will just be a game changer for me. ### 5/5 — Allergy stuffy nose *2026-06-03, version 1.4.3* One of the best devices. I suffer from spring allergies. This app with device is a saver. Tired of taking medication. Great work. I recommend to others. ### 5/5 — Unbelievable *2026-04-17, version 1.4.1* I can’t believe this works. Years of sinus pressure gone in a few sessions. I can finally breathe again. ### 1/5 — App not the product *2026-04-03, version 1.4.0* Remember ratings here are for apps not products. Product is awesome. I stopped using nasal sprays. App has a lot to be desired. Specifically when two people are sharing one. The Bluetooth driver needs to be able to connect to two devices at the same time. Sometimes I spend more than 10 min connecting and give up. ## Frequently asked questions about Sonu ### What does the Sonu app do?
