About this app

- WHAT IS JUKUSUI?
JUKUSUI is a Japanese word that means “deep sleep” or “profound sleep.”
We will support to get good sleep for people all over the world through our app from Japan.

【about JUKUSUI APP】
JUKUSUI is a multi-functional alarm clock designed to support and improve your sleep.

◆Lull Sounds
The healing lull sound will be played to induce peaceful sleep.

◆Smart Alarm
It detects your light sleep and wakes you up. We recommend this for those who always wake up feeling tired, who turn off the alarm only to fall back to sleep or who have trouble waking up in the morning due to hypotension.

◆Sleep Report
Tap the "Bedtime" button to sleep, swipe to turn off the alarm and get your daily sleep log to find out your sleep (quality, sleep efficiency, and hours of sleep) and snoring (hours of snoring and volume).

◆Cloud Service
This is a service to keep all of your Sleep Log on the dedicated server safely. All you need to do is signing up for this service on the app. After logging in, your daily sleep logs are automatically updated to the server. You don't need to work for backing up the data. When you change your device, you can transfer the data from your old device to the new one. This is a free service.

Best alarm app. It wakes you up when your sleep cycle is favorable. You can make weekly schedules. Just set it once and forget it. Annoying ads though.

Decided to use this app again after some time. Good old days where watching ads grant permission to download lull sounds and simpler yet more intuitive interface... Right now somewhat ok. But the app pushes premium plan rather often
