About this 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.

Very comprehensive sleep recording app! Plenty of statistics and features set. I really like it! Some minor asks would be: * Add a note field to each sleep entry to store some sleep-relevant info like: "had some drinks", "ill with the flu", "took anti-snore medicine x" * Add an option to stop the site-related notifications which are in Japanese. * Add a page for feedback and suggestions😀

熟睡アラームサポート担当です。いつも熟睡アラームをご利用いただきまして誠にありがとうございます。睡眠には「脳や身体の休養」「疲労回復」「免疫機能の増加」「記憶の固定」「感情整理」など多くの重要な役割があります。睡眠中は体内の修復・回復を促す成長ホルモンが多く分泌され、体内での代謝活動が促進されます。 脳も休まり、自律神経の働きが整うため、ストレスからの回復・耐性も向上します。熟睡アラームは睡眠の浅いタイミングで起こしてくれるスマートアラーム機能や入眠をサポートする熟睡サウンド機能等の睡眠サポート機能をご利用いただきつつ、継続してご利用いただくことでユーザ一人一人にあった睡眠リズムを発見することができます。引き続き熟睡アラームをご愛顧くださいますようお願い申し上げます。

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.
