What does it mean to be powered by SleepScore?
While using the Sleep.com app, you’ve probably noticed that some features and elements include a “Powered by SleepScore” badge. We utilize SleepScore’s renowned sleep-tracking technology, expert-backed advice, and other innovative features to give you the tools you need to sleep better — all in a single easy-to-use app.
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.
How does the Sleep.com app track my sleep?
The Sleep.com app utilizes patented sonar technology to track your sleep without any wearable device. Using your phone’s speakers and microphone, the app sends and receives silent signals that assess your overall sleep based on your breath and movement. And don’t worry, we never record anything.
How does the Sleep.com app use my phone’s speakers and microphone to track my sleep?
The Sleep.com app uses sonar technology to accurately track your sleep. Just like the echolocation that bats use to sense their surroundings at night, the app sends silent signals into your sleep environment. When these sound waves reflect into your microphone, our advanced algorithm interprets their shape and movement — determining your breathing rate, assessing your body movement, and turning those insights into an accurate record of your nightly sleep patterns.
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 does the Sleep.com app compare to other sleep tracking products?
The Sleep.com app uses patented sonar technology that measures your breathing rate and body movement to accurately track your journey through the sleep cycle. Our app uses your smartphone’s speakers and microphone, so you don’t have to wear any tracking device. And because you place your phone on your bedside table before starting your sleep session, the app is completely contact-free, too.
Verified against Actigraphy and Polysomnography (PSG), the only two clinically accepted standards of measuring sleep, the app’s algorithm leverages more than 12 years of research and 6 million nights of sleep data. When we say the Sleep.com app is the most accurate way to track your sleep outside of a sleep lab, we’ve got the proof to back it up.
How does the Sleep.com app help me improve my sleep?
The Sleep.com app tracks your breathing and body movement as you travel through each sleep stage. This data, combined with the profile and lifestyle information that you provide in the app, unlocks deep insights into your unique sleep patterns and overall sleep health. The result? Actionable, customized advice that helps you sleep better.
The Sleep.com app is home to a series of interactive tools that help you understand how you sleep, all available in the free version. Sleep tracking and your SleepScore are just the beginning. Explore personalized recommendations from world-leading sleep specialists and use the Smart Alarm to wake up at the right time in your sleep cycle. Set goals that help you measure your journey toward better sleep and get product recommendations to optimize your sleep environment. And every step of the way, view your seven-day Sleep History to easily identify trends in your SleepScore, breathing rate, and more.
With a Sleep.com Premium account, you get even more tools to help you sleep better. For less than the cost of one latte per month, participate in subscriber-only Sleep Challenges, explore in-depth data visualizations, and tap into the power of lifetime sleep history analytics. You’ll also have access to CheckUp, a sleep screener that identifies any concerning patterns in your data, and Sleep Report, which provides a 30-day sleep analysis to share with your doctor. If your CheckUp identifies potential sleep disorder risks, that information will also be included in your Sleep Report.
Can the Sleep.com app track two people at the same time?
A single Sleep.com app can only record one person’s sleep at a time. However, multiple people in the same house can use their apps simultaneously if they’re not sleeping in the same bed.
If you’re using the Sleep.com app and your bed partner isn’t, no problem! Just place your phone closest to you so that you get an accurate read. If both you and your bed partner want to track your sleep in the same room at the same time, your apps will interfere with one another and produce inaccurate results. One solution? One person can use the Sleep.com app and the other can track with SleepScore Max.
Learn more about
Will my app track my sleep properly if there’s someone else in my room?
Yes. Our SleepScore technology is designed to track the person closest to the smartphone in use. Having two sleepers in the bed won’t affect your results, but remember, only one person can track their sleep at a time.
Can there be two sleep sessions in progress in the same room at the same time?
If there are two sessions in the same room, they will interfere with each other and produce inaccurate sleep data. One workaround? One sleeper can use the Sleep.com app and the other can use SleepScore Max.
Learn more about
Does the Sleep.com app work while I’m using a CPAP?
Yes! Your CPAP machine won’t cause any inaccuracies in your SleepScore.
When should I start and stop my sleep session?
Start your sleep session as soon as you’re ready to go to bed; that way, the app can accurately reflect how long it took for you to fall asleep. In the morning, stop your sleep session as soon as you wake up.
Should I be concerned if I hear a noise from my smartphone when I start a sleep session?
Before the start of each sleep session, the app performs a quick 30-second environment and phone check. If you hear quiet popping or clicking sounds coming from your phone’s speakers, that’s just the app doing its job. Your phone might also click softly throughout the night; this is normal and varies from phone to phone.
Features & Functionality
Will the Sleep.com app work when my smartphone screen is locked?
The Sleep.com app will track your sleep regardless of whether your screen is locked or unlocked. If your screen is unlocked, the app will dim your phone’s display so the brightness doesn’t disrupt your sleep. If you lock your screen and use the Smart Alarm feature, you’ll need to unlock your phone to disable the alarm.
Why do I need to charge my smartphone during a sleep session?
Through extensive testing, we’ve found that the Sleep.com app delivers the most stable results when a device is charging. By keeping your phone plugged in, you also avoid the risk of your battery dying mid-session, which would leave you with an incomplete tracking session.
Can I use my smartphone while I'm tracking a sleep session?
Yes. However, tracking will automatically pause any time your phone moves. This prevents your phone from picking up poor signals that could lead to inaccurate results.
Why does the app pause when I pick up my phone?
During your sleep session, loud sounds from your bedroom or phone can affect the accuracy of the app’s sonar sensor. For this reason, the app automatically pauses your sleep tracking any time you move your phone from your bedside table. Tracking automatically resumes once your phone is back on a level surface with no other apps playing sounds.
Can I listen to music on my smartphone while I’m tracking my sleep?
Unfortunately, no. Music and other sounds from your phone will interfere with the Sleep.com app’s sonar signal. The app will stop tracking if you’re playing music, taking a call, or using other apps during your sleep session. Once all sounds are off and your phone is back on your nightstand, your tracking will automatically resume.
What happens to my sleep record when the time changes?
The Sleep.com app automatically accounts for daylight saving time, ensuring your sleep record remains accurate despite the time change. And here’s the best part: You’re not required to do anything differently! On the night when the clocks “roll back,” the app will record two 1 a.m. time slots. That’s because when the clock strikes 2 a.m., the app records your data and then rolls back to 1 a.m. — showing two results for the “same” time. However, there’s no lost time, your sleep duration will be accurate, and the Sleep.com app accounts for the time change with no action from you.
When it’s time to “spring forward,” the app accounts for that as well, adjusting your sleep duration by one hour when the clock jumps from 2 a.m. to 3 a.m.
What is the Breathing Rate feature?
Your nightly breathing rate is one measure of your overall health. The Sleep.com app tracks your breathing rate while you sleep and provides this data as a nightly average that makes it easy to identify any unusual increases.
To view your breathing rate, navigate to the History tab in the Sleep.com app. Then, tap the Breathing Rate icon to see your daily data in a convenient weekly view.
What is considered a healthy average breathing rate?
The average breathing rate for adults typically ranges from 12 to 20 breaths per minute. In the Sleep.com app, you can review your daily averages by tapping the Breathing Rate icon in the History tab. If you’re concerned about your nightly average, please seek additional guidance from your healthcare provider.
Questions About Sonar
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
Which sound frequencies are used for tracking?
During your sleep session, the Sleep.com app only processes the sonar signals in its range, ignoring other sound frequencies. At the end of every sleep session, all audio data is destroyed. The Sleep.com app never saves or stores the sounds collected during your sleep tracking, and the same is true for SleepScore Max.
Learn more about
how the Sleep.com app works
Can I hear the sonar signals while my sleep is being tracked?
The Sleep.com app uses sonar at sound frequencies above the level of adult human hearing. Because children and young adults can hear different sound frequencies than adults, in some cases they have reported hearing the app’s sensor sounds. However, this has not been shown to create any ongoing disturbance in children or young adults.
Can pets hear the sonar signals used in the Sleep.com app?
When tracking your sleep, the Sleep.com app uses advanced sonar at sound frequencies above the level of adult human hearing. Because pets have more sensitive hearing than humans, they could possibly hear the app’s sonar frequencies. However, our extensive testing has shown that this does not pose any risk to pets.
What is SleepScore Max?
SleepScore Max is a sleep-tracking sensor that measures the quality and quantity of your sleep from a bedside table — no wearable required. As you sleep, the SleepScore Max sensor measures your movement and breathing, plus the light and temperature levels in your bedroom. Each morning, you’ll receive a personalized SleepScore™ based on these analytics, available in a companion app packed with personalized, science-based advice to help you improve your sleep.
SleepScore Max provides the most accurate non-contact sleep tracking outside of a sleep lab, and its accuracy has been validated in more than a dozen published studies . Although everyone sleeps differently, SleepScore Max technology has been shown to enhance sleep quality within just one week of use.

What is the difference between the Sleep.com app and SleepScore Max?
SleepScore Max is hardware that sits on your bedside table, whereas the Sleep.com app lives within your smartphone. Although they both deliver the same level of accuracy and employ the same algorithm, they use different technologies to calculate your SleepScore.
The Sleep.com app uses patented sonar technology, which relies on your phone’s microphone and speakers to send and receive silent signals into your sleep environment. SleepScore Max uses super low-powered radio waves to measure your movements and breathing. Unlike the app, SleepScore Max has environmental sensors that measure the light and temperature levels in your bedroom. These key details can help you create the optimal environment for high-quality sleep.
Both the app and SleepScore Max calculate your SleepScore using our proprietary algorithm, which leverages more than 6 million nights of sleep and 12 years of software development to deliver the most accurate way to measure your sleep outside of a sleep lab — no wearable required.
Which is more accurate, the Sleep.com app or SleepScore Max?
The Sleep.com app and SleepScore Max use the same algorithm to assess your sleep. This algorithm is based on more than 6 million nights of sleep and 12 years of technology research. While you initially might notice a two- or three-point difference between your scores in the app and SleepScore Max, this should even out over time. Whether you use the Sleep.com app or SleepScore Max, rest assured that you’re getting the most accurate non-contact sleep tracking available outside of a sleep lab.
Can I use the Sleep.com app and SleepScore Max to track my sleep at the same time?
No. Because SleepScore Max and the Sleep.com app both use your phone’s microphone, it’s not possible to track your sleep with both simultaneously.
If you share a room with someone who wants to track their sleep, we recommend that one of you use SleepScore Max and the other use the Sleep.com app.
What should I do if my SleepScore™ doesn’t seem accurate?
It can take a few nights of consecutive sleep tracking to establish a consistent baseline and begin identifying SleepScore trends. If your SleepScore still doesn’t seem accurate after a few days of using the app, check the following common sources of interference:
- Phone positioning: Watch this video to ensure you have the correct phone setup.
- Electronic devices: Is there any sound interference in your sleep environment? Sound machines, fans, TVs, stereos, and other noisy electronics could cause issues if they’re less than 3 to 6 feet from your phone or are set to a high volume. For the best results, turn off all electronic devices that emit noise throughout the night.
- Microphone and speakers: Make sure your microphone and speakers are functioning and aren’t blocked by your phone case. Otherwise, you could see abnormalities in your sleep tracking data.
- Multiple apps: If another Sleep.com app is used in your room, it can cause inaccuracies in your SleepScore. Only use one app per room.
- Phone usage: During your sleep session, keep your phone charging and limit its use. If your phone is unplugged and/or frequently used during your session, our tracking technology automatically pauses. This creates an incomplete reading of your sleep duration.
The Sleep.com app performs an interference check at the start of each sleep session. If it identifies any of the above issues, you’ll receive an automated alert.
What can interfere with my sleep recording throughout the night?
The most common types of interference are related to your phone and other electronic devices in your sleep environment. The Sleep.com app performs an interference check at the start of each sleep session and will tell you the next morning whether it identifies any of these issues.
- Incorrect phone setup and positioning; watch our video for a quick refresher
- A phone case that blocks your microphone and/or speakers
- Speakers and microphones that don’t work properly
- Unplugging your phone during your sleep session
- Significant phone usage during your sleep session
- Sound interference from sound machines, fans, TVs, stereos, and other noisy electronic devices positioned less than 3 to 6 feet from your phone
- Another Sleep.com app being used in the room
Electronic devices should not cause interference if they are set to a low volume and positioned at least 3 to 6 feet from your phone. However, we suggest turning off any devices that may make sounds throughout the night to ensure the best results.
Do television sounds interfere with my SleepScore?
If your TV is positioned less than 3 to 6 feet from your phone and is set to a high volume level, it could interfere with your sleep tracking. The type of noise emitted also impacts whether a TV causes interference. Although our app automatically identifies potential issues before each sleep session, we recommend turning off all electronic devices that make noise.
Do electronic devices interfere with the accuracy of my sleep tracking?
Some electronic devices could cause interference based on the type and volume of sound emitted and their location in your room. Although the Sleep.com app automatically identifies interference issues at the start of each sleep session, we recommend turning off all electronic devices that make noise to ensure the best results.
Do bed covers, pillows, or other bedding interfere with the app’s sonar sensor sleep tracking?
No! We’ve tested products of all weights, sizes, and densities to ensure that your bedding will not interfere with our app’s ability to accurately track your sleep.
Will air conditioning or an electric fan interfere with my sleep tracking?
The Sleep.com app performs an interference check at the start of each sleep session to ensure you’re set up for success. However, air conditioners and electric fans could cause interference depending on their proximity to your phone, their volume level, and the type of sound they emit. For the best results, turn off all electronic devices that make noise before you start tracking or position them at least 3 to 6 feet from your phone.
What should I do if my sleep record shows periods of no signal?
If your sleep record shows periods of no signal, start by exploring these common issues:
- Is your phone positioned incorrectly? Watch this video for a quick how-to.
- Is there any sound interference in your sleep environment? If you have sound machines, fans, TV, stereos, and/or noisy electronics in your room, try positioning them at least 3 to 6 feet from your phone and lowering their volume.
- Is your phone case blocking your microphone or speakers? If so, try removing your case before starting your next sleep session.
- Are your speakers and microphone malfunctioning? Ensure they’re working properly before starting your sleep session.
- Is there another Sleep.com app being used in the room? For the most accurate tracking, limit usage to one app per room.
- Was your phone unplugged during your tracking session? This automatically pauses our sleep tracking technology.
- Did you use your phone a lot during the session? Limit usage to avoid pauses in your sleep tracking.
If your answer to any of these questions is “yes,” troubleshoot the issue before your next sleep session to eliminate periods of no signal. The Sleep.com app also performs a daily interference check and notifies you if it identifies any issues.
What should I do if my SleepScore is zero?
If you’ve received a zero SleepScore, that means the app’s sonar technology was paused for the entire night. This typically occurs if your smartphone is playing audio from another source, which automatically pauses your tracking session. Before your next session, disconnect your phone from all Bluetooth devices and double-check that no other apps are playing audio.
How does the Sleep.com app protect my privacy?
At Sleep.com, we take your privacy very seriously. We use a variety of technologies and procedures to protect your personal data from unauthorized access, use, and disclosure. Read our
