Welcome to SomnoRing®

At Somnology, we want to give individuals the ability to accurately and reliably track their sleep, at home or on the go. Our SomnoRing® bundles the latest technology in sleep monitoring in a sleek device that is comfortable and easy to wear. Using our Somnology App, users can quickly synchronize their device data and receive detailed sleep reports. This includes heart rate and pulse oximeter data to assist individuals with sleep apnea. The SomnoRing® is available to enterprise clients via our SLaaS® packages.
