Great alarm, and good for sleep study!
Ive been struggling with chronic fatigue for years, and I started using this app to identify nights where I wasnt sleeping well to determine if that was a factor. I love being able to see my sleep quality each night to know if thats why Im tired the next day. Its also really helped me wake up for my 5 am work shifts without feeling as groggy!
