WHAT IS JUKUSUI?

JUKUSUI, originating from Japanese, signifies "deep sleep" or "profound sleep."

Our app hailing from Japan aims to assist people worldwide in achieving quality sleep.

Common Settings for Android

Here are the settings that will be applied to the whole JUKUSUI app. It is recommended to modify these settings before using JUKUSUI app.

You can select the way to the snooze while the alarm is ringing. If you choose [No], you need to tap the screen to snooze. If you select [Snooze], you can snooze with the volume buttons or the camera button on the device.

Output Alarm Sounds Though Speaker

You can set the alarm sounds output destination when the earphone is connected. When you turn it off, both a lull sound and an alarm sound are output from the earphone. When you turn it on, the lull sound will be output from the earphones, but the alarm sound will be output from the speaker.

Snoring Logs

The Number of Logs【Premium】

You can select the number of recording data to keep on the device. Settings with a key mark are available in Premium version.

[No]: logs your snore without recording your snoring sounds.

[Sample]: The digit means the number of logs you can keep. The logs will be kept from the louder volume.

[All]: records all sounds from the start of recording to the stop of recording.

Note 1: The larger the number of recorded data, the more space the device consumes. See the following items for an estimate of the recording data capacity.

Note 2: If the free space of the device is less than 200MB, it will be automatically set to [No].

Sound Quality

You can set the sound quality (low, medium or high) of the recorded data. When you set to [High], the sound quality will be higher, but the volume of recorded data will be about twice as large as for [Low].

Record Retention Period【Premium】

Except for the data in Favorite, any data before the amount of days you specified will be automatically deleted. For the sake of convenience, the item is described in “days”, but to be accurate, it means the number of recordings. Settings with a key mark are available in Premium version.

Favorites【Premium】

You can display and play back the data in Favorites. This favorites feature is not available on the free version of the app. However, the premium version can have up to 100 favorites. In addition, the data in Favorites can be synchronized with the cloud service and you can transfer them from your old device to the new one when you change your device. Furthermore, you can confirm the recorded data on MY DATA at jukusui.com.

Adjust Microphone Sensitivity

The microphone sensitivity on Android devices are different depending on every device maker. For most devices, [± 0] is optimal, but in some cases recording may be at a higher (or lower) volume than expected. If you listen to the recorded sound and found that the environmental noise were judged as snoring sound, try lowering this value in the negative direction. Conversely, if you are snoring, but it is not being recorded as snoring, try increasing this value in the positive direction.

Delete Recorded Data

You can delete the recorded data stored in your device.

[Delete Old Data (5 days)]: deletes 5 days (5 times) of your data from the oldest data except for the data in Favorites.

[Delete All except Favorites]: deletes all data except for the data in Favorites.

[Delete All Recorded Data]: deletes all data including the data in Favorites.

Estimated Recording Data Capacity

One recorded data is equivalent to one minute.

When the sound quality is [Low], it is about 180kB per recorded data.

When the sound quality is [Low] and the number of logs is [Sample 10], the total amount of data recorded overnight is approximately 1.8 MB.

When the sound quality is [Low] and the number of logs is [All], the total amount of recorded data for 7 hours is approximately 67MB.

    You tried a few apps, but they were missing something. Then you found this one and, wow! It had that special interesting feature. That feature kept me engaged, made me want to learn more about my sleep from different angles. And guess what? My sleep is getting better! That's amazing. So, thanks to this app.

    Porn ads kept popping up randomly and I accidentally clicked on them. So frustrating that I ended up uninstalling the app. Such a shame.
