ResMed Inc., a San Diego-based company that develops medical devices for sleep apnea and other sleep-related breathing disorders, announced that its newest sleep-monitoring device will be available through Apple retail stores in the United States and from the Apple Online Store.

The device, called S+, is a personalized sleep tool that uses bio-motion sensors, designed to measure an individual's sleep stages and environment, to deliver personalized feedback that aims to improve sleep, according to ResMed.

The S+ mobile application now integrates with Apple HealthKit in iOS8 to give consumers an easy-to-read, daily snapshot of their overall health and fitness. The user report can also be shared with health care providers.

“By integrating S+ with HealthKit, we’re able to provide an easy way for Apple users to track, share and improve their own sleep habits,” said Don Darkin, president of ResMed’s sleep-disordered breathing business unit. “S+ is a sleek, portable, bedside device that tracks a person’s sleep. When paired with Apple HealthKit, S+ provides a daily sleep score that can be viewed and shared in the same manner as calories, steps walked or miles ran.”

The S+ is now available for $149.99 at Apple, Bed Bath & Beyond and Best Buy retail stores in the United States, from the Apple Online Store and online at www.mySplus.com.

The S+ ResMed App is available for free from the App Store on iPhone or at www.AppStore.com.
