FAQ

About the SleepScore App

What is SleepScore™?

SleepScore™ is the world’s most accurate sleep improvement app. The SleepScore app uses Sonar Sensor Technology to track your breathing and body movement as you travel through each sleep stage. This data, combined with your profile and lifestyle information, gives us deep insights into your unique sleep patterns. It’s how we’re able to provide you with actionable, customized advice that’s delivered through the Sleep Guide.

In the app, you will also find a series of easy-to-use, interactive tools that allow you to work with your own sleep data, allowing you to properly understand the way you sleep. You’ll have access to your sleep history, so you can compare the quality of your rest to your daily lifestyle measures, like caffeine and alcohol intake. In addition, you’ll be eligible to receive sleep solutions in the form of product recommendations, all of which have been tested by our expert team at SleepScore Labs and selected to fit your individual sleep needs.

How do I set up my smartphone to accurately track my sleep?

There are easy to follow instructions inside the SleepScore app that describe how to accurately set up your phone for the most accurate reading of your nightly sleep.

Here are the steps you should implement to set up your phone accurately:

  1. Plug in your phone before you start tracking.
  2. Place your phone no more than arm’s length away from you.
  3. Make sure the phone is above the top of your mattress, about 6 inches is ideal.
  4. Point your speakers, which are located at the base on your phone, towards your chest.
  5. Position the phone slightly off the edge of the bedside table.
  6. Keep your phone facing up, you can lock the phone if you prefer

Some other things to keep an eye one are ensuring any phone case is not blocking your phone speakers in any way.

How is my SleepScore calculated?

Your SleepScore™, powered by ResMed, is is an assessment of the quality and quantity of your sleep, plotted on a scale of 0 to 100, with the average SleepScore being 78. After tracking your sleep using SleepScore, your nightly SleepScore evaluates your rest against the following six parameters:

  • Total sleep duration
  • Time to fall asleep
  • Time in light sleep
  • Time in deep sleep
  • Time in REM (Rapid-Eye-Movement) sleep
  • Number of awakenings throughout the night

These variables are then measured against known sleep averages for your age and gender, which have been established by well-published research, expert advisors and the analysis of

over 6 million nights of sleep. Continued use of SleepScore in conjunction with adherence to the advice regarding sleep environment, health, and lifestyle should help you improve

your score.

How does SleepScore track my sleep?

Without requiring you to wear a device or place anything on your bed, SleepScore measures the quality and quantity of your sleep.

SleepScore is powered by ResMed™ Technology – used for tracking more than 6 million nights of sleep so far. This patented sonar technology uses your phone speakers and microphone as a way to send and receive silent signals, sensing your breathing and body movement so that your overall sleep can be reliably assessed. And we don’t record anything. Ever.

To maintain accuracy, SleepScore should not be used at the same time by two people in the same room.

How does SleepScore use my phone speakers and microphone to track my sleep?

Our technology harnesses the power of sonar to accurately track users as they move through different sleep stages. Sonar uses echo-location like what bats use to hunt at night. The bats make a noise and send sound waves into the environment around it. Those sound waves reflect off nearby objects, and some of them reflect back to the bats. Our app utilizes these same principles. The patented Sonar Technology uses your phone speakers as a way to send silent signals and those reflected waves are received back into the microphone.

Our advanced algorithm then interprets the shape and movement of the reflected waves to sense your breathing rate and body movement. The combination of these two signals is used to accurately decipher your movement through the various sleep stages at night.

How does it compare to other sleep tracking apps?

SleepScore’s patented technology uses sonar as a way to measure your breathing rate and body movement to accurately stage your sleep.

Most apps use accelerometer technology or the microphone alone to measure your sleep. The problem with these methods is they can only detect movement, and often do so inaccurately. If these two signals are not getting reliable readings, they cannot accurately measure sleep. The SleepScore app, powered by ResMed technology, assesses both movement and breathing rate to get the most complete picture of your sleep. ResMed spent over 12 years and analyzed more

than 6 million nights of sleep to develop the algorithms that take these two signals to accurately measure your sleep.

How does SleepScore compare to other sleep tracking products?

When it comes to sleep tracking, you won’t find anything that compares to the accuracy of SleepScore. SleepScore is different from a variety of standpoints. Firstly, SleepScore is powered by patented ResMed technology that uses sonar as a way to measure your breathing rate and body movement to accurately determine your path through the sleep stages. Secondly, it uses the speaker and microphone from your smartphone to measure your sleep, so there’s no need for stand-alone hardware like a mattress strip or wearable fitness tracker. Thirdly, it sits on your bedside table, so it’s completely non-contact! Finally, its accuracy is far superior to other non-contact sleep tracking apps. SleepScore is based on the same best in-class algorithms that SleepScore Max uses, which have been validated against Polysomnography (PSG) and Actigraphy, the two clinically accepted standards of measuring sleep, with these results published in over 10 scientific peer-reviewed papers. The algorithms have been developed over 12 years with over 6 million nights of data.

So, rest assured, just like SleepScore Max, your SleepScore app is the most accurate non-contact way to measure your sleep outside of a sleep lab.

How does SleepScore help my sleep?

SleepScore uses sonar sensor technology, called echolocation, to track your breathing and body movement as you travel through each sleep stage. This data, combined with your profile and lifestyle information that you input, gives us deep insight into your unique sleep patterns and overall sleep health. It’s how we’re able to provide you with actionable, customized advice, delivered through the Sleep Guide.

In the app, you will also find a series of easy-to-use, interactive tools that allow you to work with your own sleep data to properly understand the way you sleep. You’ll have access to your sleep history, allowing you to compare the quality of your rest to your daily lifestyle measures, like caffeine and alcohol intake. In addition, you’ll be eligible to receive product recommendations, all of which have been tested by our expert team at SleepScore Labs and selected to fit your individual sleep needs.

SleepScore vs SleepScore Max

What is the difference between the SleepScore app and SleepScore Max?

While both methods are based on the same SleepScore by ResMed algorithm, SleepScore Max utilizes dedicated hardware that sits on your nightstand to track your sleep, while the SleepScore app uses just your smartphone microphone and speaker capabilities to track and measure your sleep.

Another key difference between the two tracking abilities is the different technology each uses. SleepScore Max uses safe, ultra-low power radio waves (1/10 of Bluetooth®) to send and receive signals that measure your breathing and movements. The SleepScore app utilizes patented sonar technology which uses your phone speakers as a way to send silent signals into your bedroom environment, and those reflected waves are received back into the microphone.

Because the SleepScore app uses your microphone and speakers to send and receive sonar signals, it cannot give any details about your bedroom environment. This is where SleepScore Max’s dedicated hardware comes into play. SleepScore Max’s environmental sensors measure your light and temperature levels every night, allowing you to set your bedroom to the best settings for optimal sleep.

Both of these sleep tracking mechanisms are based on the same SleepScore by ResMed algorithm, based on over 12 years of world class software development, with the algorithm being constantly updated and advanced based on over 6 million nights of sleep data and sleep norms. There may be a two to three-point score variation when the two are compared side by side, but this should normalize and produce consistent trends over time. Rest assured, either method you choose to use is the most accurate non-contact way to measure your sleep outside of a sleep lab.

How accurate is the SleepScore app compared to SleepScore Max?

Both the SleepScore app and SleepScore Max are based on the same SleepScore by ResMed algorithm. This algorithm is based on over 12 years of world class software development and is always being updated and advanced based on over 6 million nights of sleep data and sleep norms. There may be a two to three-point score variation when the two are compared side by side due to variations in technology, but this should normalize and produce consistent trends over time. Rest assured, either method you choose to use is the most accurate non-contact way to measure your sleep outside of a sleep lab.

Can I use the SleepScore app and SleepScore Max to track my sleep at the same time?

Because SleepScore Max and the SleepScore app both require use of the microphone at the same time, it is currently not possible to use the two apps on the same smartphone to simultaneously track your sleep.

If you and your bed partner would both like to track your sleep using SleepScore, we recommend that one of you uses the SleepScore app and the other uses SleepScore Max.

Using the SleepScore app

How do I set up my smartphone to accurately track my sleep?

There are easy to follow instructions inside the SleepScore app that describe how to accurately set up your phone for the most accurate reading of your nightly sleep.

Here are the steps you should implement to set up your phone accurately:

  1.  Plug in your phone before you start tracking.
  2.  Place your phone no more than arm’s length away from you.
  3.  Make sure the phone is above the top of your mattress, about 6 inches is ideal.
  4.  Point your speakers, which are located at the base on your phone, towards your chest.
  5.  Position the phone slightly off the edge of the bedside table.
  6. Keep your phone facing up. You can lock the phone if you prefer.

Some other things to keep an eye one are ensuring any phone case is not blocking your phone speakers in any way.

Why it is important to position my smartphone correctly?

Since you only need to use your smartphone to track your sleep, it’s important to set up your smartphone correctly to get the best measurement. If you don’t, this could negatively impact the accuracy of the sleep data gathered by SleepScore.

How do I know where the speaker and microphone are located on my smartphone?

Because of the unique capability of the patented SleepScore by ResMed technology, each supported smartphone is tested and calibrated to ensure the accuracy of SleepScore. For all supported phones, the main speakers and microphone are located at the bottom of the phone, where the charging plug is located. As a reminder, it’s important to always place your speakers pointing towards your chest while tracking your sleep. This will result in the most accurate reading of your sleep.

Why does my smartphone need to be facing up?

SleepScore requires the screen be facing up towards the ceiling because of microphone and speaker position on supported smartphones. This positioning ensures the most accurate results.

Will my phone cover affect the Sleepscore app?

If the phone cover is covering either the speaker or the microphone, such as with a water proof cover, then the app might transmit or receive a poor quality signal leading to inaccurate results. If this occurs, then consider using the app without the cover. If the phone cover is not covering either the lower speaker or microphone, then there should be no issue.

Why do I need to charge my smartphone during a sleep session?

Our extensive testing has shown that by plugging in your phone, SleepScore delivers the most stable results. It’s also important to plug your phone in to make sure your battery doesn’t die mid-session and you’re sleep session won’t begin until you do. If your phone battery dies during a sleep tracking session, you won’t get your full night’s sleep recording.

Does SleepScore work with my smartphone screen locked?

SleepScore will continue recording your sleep if your phone is locked. However, we recommend keeping your phone with the screen face-up and unlocked while you are tracking your sleep for the highest accuracy. The app screen will dim while tracking to ensure the brightness doesn’t disturb your sleep.

Can SleepScore track two people at the same time?

SleepScore can only record one person’s sleep at a time. Be sure to place the phone closest to the person who is tracking their sleep. Two people in a bed does not affect the accuracy of the results.

Currently, two SleepScore apps cannot track sleep in the same room at the same time, as they will interfere with each other and produce inaccurate results. However, multiple people can use SleepScore in the same home, provided that they are tracking in different rooms.

If you and your bed partner would both like to track your sleep using SleepScore, we recommend that one of you uses the SleepScore app and the other uses SleepScore Max.

Please be aware that because both apps need to access your microphone in order to work, it’s not possible to use the same smartphone to record a sleep session using both the SleepScore app and SleepScore Max at the same time.

What if two people are in the room at the same time?

SleepScore is intelligent enough to always track the closest person to the smartphone that’s tracking. Simply make sure that the smartphone deploying SleepScore is on the bedside table next to the person you want to track. Two sleepers in the same bed have been shown to not affect accuracy but note that only one partner may track using SleepScore at a time.

Can two SleepScore sessions be in-progress in the same room at the same time?

Currently, two SleepScore sessions cannot be in-progress in the same room at the same time, as they will interfere with each other and produce inaccurate results.

Can I use my smartphone while I am tracking a sleep session?

Yes, but tracking will be automatically paused any time you move the smartphone. This ensures that if the smartphone is in motion, it will not pick up poor signals and lead to inaccurate results.

What if I hear a noise from my smartphone when I start a sleep session?

Occasionally, when starting a sleep session, it is possible to hear a small popping or clicking sound emitted through the phone’s speakers. SleepScore always performs a 30-second bedroom environment and phone check before the start of a new sleep session. In some cases, some frequent clicking may also be heard during the night but again, this is normal and varies from phone to phone

When should I start and stop a sleep session?

You should always start your sleep session as soon as you are ready to start falling asleep, so you get the best approximation of how long it takes you to fall asleep. You should stop your sleep session after your final wake period.

Can I leave my smartphone case on while tracking?

For optimal results, we recommend removing any phone cases that cover the speakers or microphone.

SleepScore will always perform a 30-second bedroom environment and phone check before the start of a new sleep session. If anything interferes with the smartphone speakers or microphone, the app will inform you of the issue and provide some troubleshooting options. One of these options may include taking off your phone case.

Why does the app pause when I pick up my phone?

During a sleep tracking session, other loud sounds in your bedroom or your phone’s positioning can interfere with the sonar sensor. To uphold SleepScore’s accuracy, if you pick up your phone during a sleep session, the tracking is paused until the phone is back on a level surface and no other apps are playing sounds. Sleep tracking will automatically resume at this point.

Does the app start or stop tracking my sleep automatically?

In order to give the most accurate readings, we do not automatically start or stop sleep tracking. We recommend you start tracking when you are trying to go to sleep and stop after your final wake to ensure most accurate results.

Technical

What sounds does the app record?

During a sleep tracking session, SleepScore and SleepScore Max only process the sonar signals in its range and ignores other sound frequencies and no sound is ever stored or saved.

Do television sounds interfere with SleepScore?

Depending on the location of your television, the volume level, and the type of sound being emitted, it is possible that television sounds may interfere with the accuracy of SleepScore.

We always perform an interference check at the start of a sleep session to check your bedroom environment. However, for best results, we recommend you turn off any electronic devices that emit sounds.

Do other electronic devices interfere with the sleep tracking?

Depending on the location of your electronic devices, the volume level, and the type of sound being emitted, it is possible that electronic devices may interfere with the accuracy of SleepScore.

We always perform an interference check at the start of a sleep session to check your bedroom environment. However, for best results, we recommend you turn off any electronic devices that emit sounds.

Do bed covers, pillows or other bedding interfere with the sonar sensor sleep tracking?

Based on our extensive testing, bedding of all weights and densities have not been shown to interfere with sleep tracking or the accuracy of the results.

Will air conditioning or an electric fan interfere with the sleep tracking?

Depending on the location of your air conditioning or an electric fan, the volume level, and the type of sound being emitted, it is possible that air conditioning or an electric fan may interfere with the accuracy of SleepScore.

We always perform an interference check at the start of a sleep session to check your bedroom environment. However, for best results, we recommend you turn off any electronic devices that emit sounds.

Can I listen to music from my smartphone while tracking my sleep?

No. It’s possible other sounds from the smartphone in use will interfere with the sonar signal. SleepScore will automatically pause your sleep session if you are playing any sounds, taking a call, or using other apps on the smartphone during a sleep session. The sleep session will automatically resume once you place your phone back into position on your bedside table.

Do I need to connect to Wi-Fi to use SleepScore?

No Wi-Fi connection is needed, but SleepScore will require a cellular connection. The SleepScore app uses very little data to analyze and back up your sleep data in the cloud, and to provide advice. This data is transferred via the cellular connection when available.

Does SleepScore use cellular data on my smartphone?

The app does use cellular data to back up your data securely in the cloud, but the amount of data required is extremely small.

How much storage data does the SleepScore app use?

The amount of data storage required is very small and should not impact your cellular plan in anyway

What happens if I my SleepScore doesn’t seem accurate?

It’s possible that interference or incorrect positioning of your phone could affect the accuracy of the sleep tracking. Some possible causes include:

  1.  Phone setup and positioning. Check out our set-up video for more details.
  2. Interference with other sounds – sound machines, fans, stereo, TV, or other loud electronics.
  3.  Phone cases that block speakers or microphone.
  4.  Issues with your smartphone’s speakers or microphone that cause them to operate abnormally.
  5.  Another SleepScore app recording a sleep session in the same room.
  6.  Electronic interference from other electronic devices.
  7.  If your smartphone becomes unplugged after starting a sleep session, the sleep tracking will automatically pause, causing you to get an incomplete reading of that night’s sleep.
  8.  If you use your phone frequently during a sleep session, this automatically forces sleep tracking to automatically pause, resulting in a potentially inaccurate reading of your time asleep.

If sounds or other electronic devices are far enough away and on low volume, they should not affect your sleep tracking.

We always perform an interference check at the start of each sleep session to check your bedroom environment. However, for best results, we recommend you turn off any electronic devices that emit sounds. When you complete a sleep session in the morning, SleepScore will tell you if it picked up something from the nightly interference check.

What can interfere with my sleep recording throughout the night?

It’s possible that interference or incorrect positioning of your phone could affect the accuracy of the sleep tracking. Some possible causes include:

  1. Phone setup and positioning. Check out our set-up video for more details.
  2.  Interference with other sounds – sound machines, fans, stereo, TV, or other loud electronics.
  3.  Phone cases that block speakers or microphone.
  4.  Issues with your smartphone’s speakers or microphone that cause them to operate abnormally.
  5.  Another SleepScore app recording a sleep session in the same room.
  6.  Electronic interference from other electronic devices.
  7.  If your smartphone becomes unplugged after starting a sleep session, the sleep tracking will automatically pause, causing you to get an incomplete reading of that night’s sleep.
  8.  If you use your phone frequently during a sleep session, this automatically forces sleep tracking to automatically pause, resulting in a potentially inaccurate reading of your time asleep.

If sounds or other electronic devices are far enough away and on low volume, they should not affect your sleep tracking.

We always perform an interference check at the start of each sleep session to check your bedroom environment. However, for best results, we recommend you turn off any electronic devices that emit sounds. When you complete a sleep session in the morning, SleepScore will tell you if it picked up something from the nightly interference check.

What sound frequencies are used for tracking?

The advanced sonar frequencies SleepScore utilizes for sleep tracking use sound waves that are known to be above the level of adult human hearing.

Can I hear the sounds of the sonar signal?

When tracking your sleep, SleepScore uses advanced sonar at sound frequencies that are known to be above the level of adult human hearing. We have had some infrequent instances of children and young adults being able to hear the sensor sounds. This is because younger people are able to hear different sound frequencies compared to adults. It has not been shown to be an ongoing disturbance to children or young adults.

Can pets hear the sonar signal?

When tracking your sleep, SleepScore uses advanced sonar at sound frequencies that are known to be above the level of adult human hearing. Due to their more sensitive hearing, it is possible that pets can hear the sonar frequencies. Our extensive testing has shown that this is not an ongoing concern for pets.

How often does the sampling of the sensor work?

The SleepScore app uses the phone’s speaker to generate an inaudible waveform. For a typical 8-hour sleep session, SleepScore will capture 1.4 billion samples of data.

Sophisticated machine learning algorithms are used to analyze these 1.4 billion samples of data in real-time to determine your SleepScore and sleep graph.

How small a movement can the sensor pick up?

The sensor has been designed to pick up shallow breathing (down to 1mm displacement).

Does the SleepScore app work while I am also using CPAP?

We have performed tests comparing CPAP and the SleepScore app. Testing has shown not to have any effect on either the performance of CPAP or sleep tracking.
