Beddr has launched SleepTuner, an FDA-registered consumer sleep wearable. SleepTuner integrates a sleep sensor with an iOS mobile app to provide personalized insights into sleep quality and actionable recommendations on how to improve it, according to Beddr.

SleepTuner measures blood oxygen (SpO2), heart rate, sleep position, and stopped breathing events.

“Poor quality sleep can lead to a greater risk of a variety of chronic conditions, like type 2 diabetes, hypertension, and depression,” says Mike Kisch, CEO and co-founder of Beddr, in a release. “The key to better sleep is breathing, and SleepTuner provides access to insights on oxygen levels that cannot be found in traditional consumer sleep trackers. We aim to empower anyone to figure out the cause of their poor sleep within a few days in the privacy of their own home.”

SleepTuner Sensor

The size of a postage stamp and the weight of a nickel, the sensor is designed for comfort when worn while sleeping over the course of multiple nights. The SleepTuner is attached to the forehead by a hypoallergenic disposable adhesive. Key to the design of the sensor is making sure it does not disrupt a user’s sleep, Beddr states.

Using optical sensors and a 3-axis accelerometer, the SleepTuner measures SpO2, stopped breathing events, heart rate, sleeping position, movement, and awakenings. Data is stored in the Beddr Cloud until it is synced with the Beddr app via Bluetooth.

In a recent study conducted at the UCSF [University of California – San Francisco] Hypoxia Lab, the Beddr SleepTuner was found to be accurate for measuring oxygen saturation levels with an error margin of  +/- 2.2% when compared to an arterial blood draw, which is within the FDA allowable error margin of +/- 3.5%.

The SleepTuner sensor connects with the free iOS Beddr app, guiding users through the Beddr “sleep tuning” process, optimally over the course of a week. The Beddr app combines the data collected by the SleepTuner sensor with self-reported sleep hygiene information to help users determine an optimal sleep position, overall sleep quality, stopped breathing events, oxygen saturation levels, and night-to-night improvements.

“The vast majority of people with sleep problems have yet to be diagnosed. SleepTuner represents a promising opportunity to reach a larger portion of the population, engage them in sleep health, and identify issues that may need attention from a doctor,” says Meir Kryger MD, professor of medicine at Yale School of Medicine, former president of the American Academy of Sleep Medicine, and member of Beddr’s Scientific Advisory Board. “The ability to get personalized insights, over multiple nights in your own bed, is a significant improvement in the patient experience.”

SleepTuner is $149, which includes the sensor, 12 adhesives, a charging cable, and protective case.
