During the past six years, we’ve written about a wide variety of sleep technology devices designed to improve sleep duration and quality. Most devices simply report on the quality of your sleep, measured most often in the amount of time you spend in light sleep, REM sleep, and deep sleep.
Beddr‘s SleepTuner uses an optical sensor and an accelerometer to monitor a range of factors that influence your sleep quality. The SleepTuner is a 5.3-gram (0.19-ounce) device that you stick to the center of your forehead with one-time-use hypoallergenic medical-grade adhesive. You wear the SleepTuner while you sleep. The 3-axis accelerometer tracks your head and airway positions. The IR and red optical photoplethysmography (PPG) pulse oximeter sensor measures blood oxygen levels (SpO2), stopped breathing events, and heart rate. The device transmits the data collected overnight to an associated smartphone app via Bluetooth Low Energy (BLE). The SleepTuner runs for up to 20 hours on a rechargeable battery. According to Beddr, the SleepTuner’s pulse oximeter exceeds the accuracy level benchmarks for FDA clearance and hospital-grade oximeters.
Beddr’s wearable doesn’t actively promote better sleep. The presentation of trends over time and the combination of reported data suggests steps you can take for better sleep. For example, if the data reveals that you have more stopped breathing events and lower quality breathing when you sleep on your back, the app may suggest that you use pillows to support going to sleep and staying in a side-sleeping position. The app derives a sleep quality score based on the collected data.
Beddr’s SleepTuner sells for $149, including the SleepTuner, a protective case, a quick start guide, 12 hypoallergenic adhesives, and a USB-C charging cable and power adapter. The device comes with a 15-day trial period with a 100% money-back guarantee. The suggested method is to use the SleepTuner for enough nights to discover helpful insights and get suggestions to improve your sleep, followed by a SleepTuner session checkup every few weeks to be sure you’re getting the results you want. Beddr sells replacement adhesives for $10 for a pack of 12. In addition to the SleepTuner, Beddr also sells an optional four-session Sleep Coaching package for $199. Sleep coaches will help you analyze and understand your data collected by wearable to device an action plan based on your sleep goals and challenges. The full coach of the coaching package is refundable if the user cancels before the second session.
