How does the Sleep.com app compare to other sleep-tracking apps?

The Sleep.com app is powered by SleepScore. SleepScore’s patented sonar technology uses echolocation to measure your movements and breathing throughout the night. The app’s proprietary ResMed algorithm analyzes that data, transforming it into an accurate, easy-to-understand view of your sleep quality. This algorithm leverages more than 12 years of research and 6 million recorded nights of sleep to provide consistently accurate sleep tracking — no wearable device required. Most apps only measure your movement and are unable to assess your breathing rate. The Sleep.com app uses both movement and breathing to offer the most complete assessment of your sleep available outside of a sleep lab.

How is my SleepScore calculated?

Your nightly SleepScore measures the quality of your sleep against the following criteria:

  • Total time asleep  
  • Time it takes to fall asleep 
  • Time spent in light sleep 
  • Time spent in deep sleep 

  • Time spent in REM sleep 
  • Number of times you woke up at night 

Our app’s algorithm compares your data to known averages for your gender and age, which have been developed based on in-depth research and more than 6 million nights of sleep studies. The average SleepScore is 78. However, within 14 nights of using our app, 60% of users fall asleep faster, 44% improve their deep sleep, and 21% sleep for longer — all factors that help boost your SleepScore over time.

Is sonar safe for sleep tracking?

Powered by SleepScore™, the Sleep.com app uses sonar technology to track your sleep safely and accurately. Using your phone’s speakers and microphone, the app sends and receives sound waves that help us assess your sleep quality based on breathing and movement. We encounter sound waves in our everyday life simply by communicating with others, and the frequencies used in the Sleep.com app are well within the range considered safe.

Because the app’s sound frequencies are transferred through the air rather than applied directly to the body, our technology emits minimal energy. These energy levels fall within the acceptable range cited in numerous health guidelines and publications.

Which smartphones does the Sleep.com app support?

Because speaker and microphone setups vary from one phone model to the next, our team verifies each device to ensure the most accurate sleep tracking. The Sleep.com app supports the following devices, each of which has been fully verified:

IOS:
  • iOS software 11.2 and above 
  • iPhone 6 and 6 Plus 
  • iPhone 6S and 6S Plus 
  • iPhone 7 and 7 Plus

For the optimal app experience, we recommend using a fully supported device. If you use the Sleep.com app with an unsupported model, you’ll still be able to track your sleep but could experience some disabled features. We’re working diligently to expand our list of supported devices, so please check back regularly if you don’t see your phone included above — and consider joining our Android Early Access Program to help us validate your Android model faster.

What is the Android Early Access Program?

We’re constantly enhancing the Sleep.com app to bring you the best tools for better sleep. When you enroll in the Android Early Access Program, you’ll help us test exclusive new features and add more Android phones to our list of supported devices.

Speakers and microphones vary from one phone to the next. To ensure the Sleep.com app produces the most accurate sleep cycle data, we validate every phone model before adding it to our list of supported devices. With the help of our Early Access Program participants, we can test the Sleep.com app’s sonar technology on more unsupported Android phones at a much faster rate.

If you qualify for the program, you’ll be invited to join once you’ve downloaded and set up the Sleep.com app on your phone. During the program, you’ll have free access to the 20+ features included with Sleep.com Premium — plus new features only available to Early Access Program enrollees. Your app data will be shared with our research team, which will perform thorough testing to determine your phone’s ability to support the app’s technology. Once your program ends after 3 to 6 months, you’ll receive an additional month of Sleep.com Premium as a “thank you” for your participation.

By joining the program, you’re acknowledging that your sleep data might not meet the same level of accuracy as data produced by validated phones. Learn more about the Android Early Access Program.
