What's new:

* Bug fixes

Description:
This is your sleep partner that, unlike some conventional alarm apps, encourages you to live a healthy lifestyle, helping you fall asleep and wake up at your target time.
It is for you who stay up late playing with your smartphone and cannot wake up in the morning even if your alarm rings. With this app, however, you can keep early hours from now on.
