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.

Verdict
The clearest difference is review sentiment: Sonu at 73% against NextSense's 50%. Sonu also leads on ratings volume (232 vs 71). NextSense's advantage is rating (4.7 vs 4.4) and update cadence (every 6 days vs every 3 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
NextSense holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 232 and 71 respectively. Written reviews complicate that: 73% of Sonu's written reviews are positive against 50% of NextSense's, so the app with the better star average is not the one people write more warmly about.
Sonu ships an update every 3 weeks, NextSense every 6 days. The most recent releases landed on October 19, 2026 and October 16, 2026 respectively.
