Why Do We Snore? Snoring occurs because the muscles of the soft palate and tongue naturally lose tone over time. During deep sleep, these muscles completely relax. As you breathe in, the airflow causes the soft palate to vibrate, roughly similar to a flag fluttering in the wind—creating the familiar sound of snoring. How SNOR Works Just like any other muscle in your body, your tongue and soft palate benefit from regular, targeted exercise to maintain their tone and volume. Because tensing these hidden muscles voluntarily is difficult, the SNOR technology was created to guide you. Using smart sensor technology, the SNOR device measures your actual muscle tension while you exercise. The companion app connects to the device to provide real-time feedback: Visual Guidance: Watch how your muscles flex on your screen while performing exercises. Smart Adjustments: The app evaluates your muscle tone and selects the optimal training load for your current level. Progress Tracking: Get continuous corrections and track your results over time. Your Daily Routine Quick Workouts: Each training session takes just 10 to 15 minutes. Consistency: Train daily for two to three weeks to strengthen your muscles, noticeably reduce snoring sounds, and promote quieter, more restful sleep. Added Facial Fitness Benefits The tongue muscle training utilizes the principles of "Mewing." In the cosmetic and wellness space, this technique is widely recognized as an effective way to train facial muscles, target a double chin, and support a more defined, youthful-looking face. Disclaimer: SNOR is designed for general fitness, wellness, and sleep hygiene. It is not a medical device and is not intended to diagnose, treat, cure, or prevent any medical condition or sleep disorder, including sleep apnea. If you suspect you have a medical condition, please consult a healthcare professional.

Open Bridge is for adults ages 18+ to collect data for research studies. The Open Bridge app lets you contribute data for research. It is used by many research organizations who study cognition. If you choose to join a Open Bridge study, you will use the free app to complete activities on your phone on a pre-set schedule. The activities may resemble puzzles, or they may test your memory. The data collected from the activities help researchers learn more about cognition. Your data will only be used for research. We will not collect your name through the app. This helps protect your identity. Every research study is different, but most studies will take about 30-40 minutes each week and will last for different lengths of time. If you are already part of a Mobile Toolbox study, you can contact your Study Coordinator if you have questions about the study you have joined. Sage Bionetworks, a non-profit research organization in the USA, developed the Open Bridge app. Washington University and Sage Bionetworks developed the activities on the app. Open Bridge supports research studies.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Open Bridge holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 4 and 5 respectively.
