Ever wake up in the morning and still feel completely exhausted? You're probably waking up during a deep sleep phase of your sleep cycle. Studies show that waking up during a light sleep phase is better.
That's why Gentle Alarm exists. It plays a quiet alarm 30 minutes before the time you set. That can wake you from a light sleep phase. Otherwise a standard alarm will wake you at your set time. It's a simple tool to help you wake up correctly. That can make all the difference in your day.
