Overview

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. By purchasing the subscription, all Premium features are available for free and all in-app ads are hidden. The subscription fee will be charged to your Google ID. Offer the free trial per Google ID. The subscription fee will be charged within hours before the end of the free trial. To cancel it during the free trial period, please proceed with the procedure more than hours before the trial ends. The subscription fee will be charged within hours before the expiration date. You can cancel the updates more than hours before the expiration date. The subscription fee is non-refundable even if there is a time period of use when canceling your subscription. For cancellation of the updates, you can do it on MENU on Google Play.
