TECHNOLOGY
01Measuring sleep
Measure
Analyze sleep state with
unprecedented accuracy
Incorporating a uniquely developed algorithm based on sleep research and applying technology used in sleep studies. It reveals your sleep stages (depth of sleep), sleeping posture, snoring/environmental sounds, and bed temperature (temperature inside the futon), which could not be seen with previous sleep measurement devices.

Visualize the "depth of sleep"
Our unique sleep stage determination algorithm and sensors categorize sleep into four depths: [Awake], [REM sleep], [Light sleep], and [Deep sleep], and visualize the duration of each. Knowing when you are awake and how much deep sleep you are getting helps you create your optimal sleep rhythm.
Using Sleep Coin (device)
improves accuracy.
Evaluates "Sleep Score"
based on sleep efficiency, etc.
By analyzing sleep duration, sleep efficiency, and other sleep conditions, your sleep is given a score. Daily measurements allow you to track changes in your sleep status weekly and monthly. Aim for a high score!
Visualize and record "snoring/environmental sounds"
that you are unaware of.
You probably have no idea about your snoring while you sleep, but with this device's app, you can easily measure and visualize snoring, analyzing when and how loud your snoring is.
Furthermore, AI analyzes sounds, distinguishing and recording snoring from environmental sounds.
You can also listen to your snoring, arranged from loudest to quietest.
You might not know it,
but what's your optimal sleeping position?
Do you sleep on your back, stomach, or side?
By overlaying this with your sleep stages, you can see which position you're in when you experience deep sleep.
For those suffering from snoring, knowing which position minimizes snoring can be a valuable clue to achieving better sleep.

Measure your body's condition
by the number of tosses and turns
Tossing and turning is an important factor related to "sleep state" and "body condition." Using a mattress or pillow that doesn't fit you can lead to an extremely low number of tosses and turns.

Measure "bed temperature,"
which affects your sleep
Who hasn't woken up in the middle of the night feeling too hot or too cold? Controlling "bed temperature" is crucial for sleep. Understanding the temperature while you sleep and adjusting temperature control according to the seasons will help you create an optimal sleep environment.

How to attach
Attach to the waist
Zero discomfort as it doesn't touch the skin directly
The clip type is easy for children to attach and difficult to remove. The silicone clip is soft to the touch and causes no stress during sleep.
Can measure sleep for both adults
and children
Sleep problems affect not only adults but also children in various ways. The nocturnalization of children's lifestyles and reduction in sleep duration have many impacts on their daily lives. Accurately understanding children's sleep can be utilized to support their daily lives.

FAQFrequently Asked Questions
About the App
Is the app itself free?
The app is free to use.
While paid features may be added in future updates,
please rest assured that currently, none of the features provided to you are paid, nor will any current free features become paid in the future. There are no monthly fees even with continuous use.
Are there any communication charges?
During measurement, the connection is via Bluetooth, so no communication charges will be incurred. However, communication will occur when using the app for purposes other than measurement, such as downloading music, exchanging coupons, or reading articles.
How much smartphone battery does the app consume during use?
When measuring sleep with the Brain Sleep Coin app, it consumes 40-50% of the smartphone battery overnight, depending on the degradation of the battery.
We recommend using it while charging.
Can I use it with iPhone ○○?
There are no restrictions on models as long as your smartphone supports the following versions:
・iOS 15 and later
・Android 12 and later
Can it be measured multiple times a day?
Measurement is limited to once a day. The first measurement data will be overwritten if a second measurement is taken.
How is snoring measured if someone else is snoring?
While individual sleep states can be measured,
it is not possible to distinguish between your own snoring and that of others, so there is a possibility that snoring from others may also be detected.
If you wish to collect sound data primarily from yourself, placing your smartphone device as close to yourself as possible during measurement will allow for more accurate recording than when it is further away.
Does it have a snooze function?
The snooze function for wake-up alarms can be set within the app if you set an alarm there. If you prefer to wake up using your smartphone's alarm function, you can turn off the in-app alarm and use your phone's alarm. (In that case, you will need to open the app and stop the measurement when you wake up.)
Does it link with healthcare apps?
Currently, there is no data display linked to healthcare apps.
There is a possibility that future updates may utilize data linked with healthcare apps within Brain Sleep Coin to further enhance the app.
How to use the coin
Can I measure with just the Brain Sleep Coin?
This product requires the use of an app for measurement, so measurement is possible using both the app and the device. The device alone cannot perform measurements.
Can two people measure with one Brain Sleep Coin?
It is possible for two people to use one Sleep Coin, but each person will need to download the app separately.
You can unlink the coin in the app, and then link it with another app to allow two people to use one coin. However, it can only be used by one person at a time, not simultaneously by two people.
If I buy two Sleep Coins for two people, can I see both people's data in one app?
One Sleep Coin corresponds to one app.
Therefore, you cannot view the data of two Sleep Coins (two people) in one app. Also, only one sleep data can be recorded per day.
Can it be used with a dress?
This product is designed to be attached to the waist of pants, so it cannot be used with a dress.
How do I replace the battery in the main unit?
No tools such as screwdrivers are required; it can be replaced manually.
Please refer to the instruction manual after purchase for details.
Battery: CR2032 coin cell battery (3V)
How long does the battery last?
It varies depending on the usage environment and frequency, but typically lasts about 4 to 6 months.
*The initial battery included is for testing purposes, so there may be individual differences in remaining charge.
Can the smartphone be used even if it is in another room?
While snoring cannot be measured, measurement is possible within the Bluetooth range. *You will still need to press the start button for measurement.
