JUKUSUI is a multi-functional alarm clock designed to support and improve your sleep. The healing lull sound will be played to induce peaceful sleep. 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. 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). 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.
